PSoC® Functional Overview
The PSoC family consists of on-chip controller devices, which
are designed to replace multiple traditional microcontroller unit
(MCU)-based components with one, low cost single-chip
programmable component. A PSoC device includes
configurable analog and digital blocks, and programmable
interconnect. This architecture allows the user to create
customized peripheral configurations, to match the requirements
of each individual application. Additionally, a fast CPU, Flash
program memory, SRAM data memory, and configurable I/O are
included in a range of convenient pinouts.
The architecture for this device family, as shown in the Logic
Block Diagram on page 2, consists of three main areas:
The Core
Analog System
System Resources (including a full-speed USB port).
A common, versatile bus allows connection between I/O and the
analog system.
Depending on the PSoC package, up to 36 GPIO are included in
the CY8C24x93 PSoC device. The GPIO provides access to the
MCU and analog mux.
PSoC Core
The PSoC Core is a powerful engine that supports a rich
instruction set. It encompasses SRAM for data storage, an
interrupt controller, sleep and watchdog timers, and IMO and
ILO. The CPU core, called the M8C, is a powerful processor with
speeds up to 24 MHz. The M8C is a 4-MIPS, 8-bit
Harvard-architecture microprocessor.
Analog system
The analog system is composed of an ADC, two comparators
and an IDAC. It has an internal 0.8 V, 1 V or 1.2 V analog
reference. All the pins can be configured to connect to the analog
system.
ADC
The ADC in the CY8C24x93 device is an incremental
analog-to-digital converter with a range of 8 to 10 bits supporting
signed and unsigned data formats. The input to the ADC can be
from any pin.
IDAC
The IDAC can provide current source up to 512 µA to any GPIO
pin. In the CY8C24x93 family of devices 4 ranges of current
source can be implemented that can vary in 255 steps, and are
connected to analog mux bus.
Comparator
The CY8C24x93 family has two high-speed, low-power
comparators. The comparators have three voltage references,
0.8 V, 1.0 V and 1.2 V. Comparator inputs can be connected from
any pin through the analog mux bus. The comparator output can
be read in firmware for processing or routed out via specific pins
(P1_0 or P1_4).
The output of the two comparators can be combined with 2-input
logic functions. The combinatorial output can be optionally
combined with a latched value and routed to a pin output or to
the interrupt controller. The input multiplexers and the
comparator are controller through the CMP User Module.

2x 128
4x 256
8x 512
CY8C24X93
Document Number: 001-86894 Rev. *B Page 6 of 65
Analog Multiplexer System
The Analog Mux Bus can connect to every GPIO pin and can be
internally connected to the ADC, Comprators or the IDAC.
Other multiplexer applications include:
Chip-wide mux that allows analog input from any I/O pin.
Crosspoint connection between any I/O pin combinations.
Additional System Resources
System resources provide additional capability, such as
configurable USB and I2C slave, SPI master/slave
communication interface, three 16-bit programmable timers,
software 8-bit PWM, low voltage detect, power on reset, and
various system resets supported by the M8C.
The merits of each system resource are listed here:
The I2C slave/SPI master-slave module provides
50/100/400 kHz communication over two wires. SPI
communication over three or four wires runs at speeds of
46.9 kHz to 3 MHz (lower for a slower system clock).
Low-voltage detection (LVD) interrupts can signal the
application of falling voltage levels, while the advanced
power-on-reset (POR) circuit eliminates the need for a system
supervisor.
A register-controlled bypass mode allows the user to disable
the LDO regulator.
An 8-bit Software PWM is provided for applications like buzzer
control or lighting control. A 16-bit Timer acts as the input clock
to the PWM. The ISR increments a software counter (8-bit),
checks for PWM compare condition and toggles a GPIO
accordingly. PWM Output is available on all GPIOs.

Development Tools
PSoC Designer™ is the revolutionary integrated design
environment (IDE) that you can use to customize PSoC to meet
your specific application requirements. PSoC Designer software
accelerates system design and time to market. Develop your
applications using a library of precharacterized analog and digital
peripherals (called user modules) in a drag-and-drop design
environment. Then, customize your design by leveraging the
dynamically generated application programming interface (API)
libraries of code. Finally, debug and test your designs with the
integrated debug environment, including in-circuit emulation and
standard software debug features. PSoC Designer includes:
Application editor graphical user interface (GUI) for device and
user module configuration and dynamic reconfiguration
Extensive user module catalog
Integrated source-code editor (C and assembly)
Free C compiler with no size restrictions or time limits
Built-in debugger
In-circuit emulation
Built-in support for communication interfaces:
Hardware and software I2C slaves and masters
Full-speed USB 2.0
Up to four full-duplex universal asynchronous
receiver/transmitters (UARTs), SPI master and slave, and
wireless
PSoC Designer supports the entire library of PSoC 1 devices and
runs on Windows XP, Windows Vista, and Windows 7.
PSoC Designer Software Subsystems
Design Entry
In the chip-level view, choose a base device to work with. Then
select different onboard analog and digital components that use
the PSoC blocks, which are called user modules. Examples of
user modules are analog-to-digital converters (ADCs),
digital-to-analog converters (DACs), amplifiers, and filters.
Configure the user modules for your chosen application and
connect them to each other and to the proper pins. Then
generate your project. This prepopulates your project with APIs
and libraries that you can use to program your application.
The tool also supports easy development of multiple
configurations and dynamic reconfiguration. Dynamic
reconfiguration makes it possible to change configurations at run
time. In essence, this lets you to use more than 100 percent of
PSoC’s resources for an application.
Code Generati on Tools
The code generation tools work seamlessly within the
PSoC Designer interface and have been tested with a full range
of debugging tools. You can develop your design in C, assembly,
or a combination of the two.
Assemblers. The assemblers allow you to merge assembly
code seamlessly with C code. Link libraries automatically use
absolute addressing or are compiled in relative mode, and linked
with other software modules to get absolute addressing.
C Language Compilers. C language compilers are available
that support the PSoC family of devices. The products allow you
to create complete C programs for the PSoC family devices. The
optimizing C compilers provide all of the features of C, tailored
to the PSoC architecture. They come complete with embedded
libraries providing port and bus operations, standard keypad and
display support, and extended math functionality.
Debugger
PSoC Designer has a debug environment that provides
hardware in-circuit emulation, allowing you to test the program in
a physical system while providing an internal view of the PSoC
device. Debugger commands allow you to read and program and
read and write data memory, and read and write I/O registers.
You can read and write CPU registers, set and clear breakpoints,
and provide program run, halt, and step control. The debugger
also lets you to create a trace buffer of registers and memory
locations of interest.
Online Help System
The online help system displays online, context-sensitive help.
Designed for procedural and quick reference, each functional
subsystem has its own context-sensitive help. This system also
provides tutorials and links to FAQs and an Online Support
Forum to aid the designer.
In-Circuit Emulator
A low-cost, high-functionality in-circuit emulator (ICE) is
available for development support. This hardware can program
single devices.
The emulator consists of a base unit that connects to the PC
using a USB port. The base unit is universal and operates with
all PSoC devices. Emulation pods for each device family are
available separately. The emulation pod takes the place of the
PSoC device in the target board and performs full-speed
(24 MHz) operation.

Designing with PSoC Designer
The development process for the PSoC device differs from that
of a traditional fixed-function microprocessor. The configurable
analog and digital hardware blocks give the PSoC architecture a
unique flexibility that pays dividends in managing specification
change during development and lowering inventory costs. These
configurable resources, called PSoC blocks, have the ability to
implement a wide variety of user-selectable functions. The PSoC
development process is:
1. Select user modules.
2. Configure user modules.
3. Organize and connect.
4. Generate, verify, and debug.
Select User Modules
PSoC Designer provides a library of prebuilt, pretested hardware
peripheral components called “user modules”. User modules
make selecting and implementing peripheral devices, both
analog and digital, simple.
Configure User Modules
Each user module that you select establishes the basic register
settings that implement the selected function. They also provide
parameters and properties that allow you to tailor their precise
configuration to your particular application. For example, a PWM
User Module configures one or more digital PSoC blocks, one
for each eight bits of resolution. Using these parameters, you can
establish the pulse width and duty cycle. Configure the
parameters and properties to correspond to your chosen
application. Enter values directly or by selecting values from
drop-down menus. All of the user modules are documented in
datasheets that may be viewed directly in PSoC Designer or on
the Cypress website. These user module datasheets explain the
internal operation of the user module and provide performance
specifications. Each datasheet describes the use of each user
module parameter, and other information that you may need to
successfully implement your design.
Organize and Connect
Build signal chains at the chip level by interconnecting user
modules to each other and the I/O pins. Perform the selection,
configuration, and routing so that you have complete control over
all on-chip resources.
Generate, Verify, and Debug
When you are ready to test the hardware configuration or move
on to developing code for the project, perform the “Generate
Configuration Files” step. This causes PSoC Designer to
generate source code that automatically configures the device to
your specification and provides the software for the system. The
generated code provides APIs with high-level functions to control
and respond to hardware events at run time, and interrupt
service routines that you can adapt as needed.
A complete code development environment lets you to develop
and customize your applications in C, assembly language, or
both.
The last step in the development process takes place inside
PSoC Designer’s Debugger (accessed by clicking the Connect
icon). PSoC Designer downloads the HEX image to the ICE
where it runs at full-speed. PSoC Designer debugging
capabilities rival those of systems costing many times more. In
addition to traditional single-step, run-to-breakpoint, and
watch-variable features, the debug interface provides a large
trace buffer. It lets you to define complex breakpoint events that
include monitoring address and data bus values, memory
locations, and external signals.

4. On power-up, the SDA(P1[0]) drives a strong high for 256 sleep clock cycles and drives resistive low for the next 256 sleep clock cycles. The SCL(P1[1]) line drives
resistive low for 512 sleep clock cycles and both the pins transition to high impedance state. On reset, after XRES de-asserts, the SDA and the SCL lines drive
resistive low for 8 sleep clock cycles and transition to high impedance state. Hence, during power-up or reset event, P1[1] and P1[0] may disturb the I2C bus. Use
alternate pins if you encounter issues.

Notes
6. 28 GPIOs.
7. The center pad (CP) on the QFN package must be connected to ground (VSS) for best mechanical, thermal, and electrical performance. If not connected to ground,
it must be electrically floated and not connected to any other signal.
8. On power-up, the SDA(P1[0]) drives a strong high for 256 sleep clock cycles and drives resistive low for the next 256 sleep clock cycles. The SCL(P1[1]) line drives
resistive low for 512 sleep clock cycles and both the pins transition to high impedance state. On reset, after XRES de-asserts, the SDA and the SCL lines drive
resistive low for 8 sleep clock cycles and transition to high impedance state. Hence, during power-up or reset event, P1[1] and P1[0] may disturb the I2C bus. Use
alternate pins if you encounter issues.

29. When VDD remains in the range from 1.71 V to 1.9 V for more than 50 µs, the slew rate when moving from the 1.71 V to 1.9 V range to greater than 2 V must be
slower than 1 V/500 µs to avoid triggering POR. The only other restriction on slew rates for any other voltage range or transition is the SRPOWER_UP parameter.
30. If powering down in standby sleep mode, to properly detect and recover from a VDD brown out condition any of the following actions must be taken:
a. Bring the device out of sleep before powering down.
b. Assure that VDD falls below 100 mV before powering back up.
c. Set the No Buzz bit in the OSC_CR0 register to keep the voltage monitoring circuit powered during sleep.
d. Increase the buzz rate to assure that the falling edge of VDD is captured. The rate is configured through the PSSDC bits in the SLP_CFG register. For the referenced
registers, refer to the Technical Reference Manual. In deep sleep/standby sleep mode, additional low power voltage monitoring circuitry allows VDD brown out
conditions to be detected and resets the device when VDD goes lower than 1.1 V at edge rates slower than 1 V/ms.

Notes
40. To wake up from sleep using I2C hardware address match event, I2C interface needs 20 ns hold time on SDA line with respect to falling edge of SCL. See the
CY8C24x93 Silicon Errata document for more details.
41. A Fast-Mode I2C-bus device can be used in a standard mode I2C-bus system, but the requirement tSU;DAT 250 ns must then be met. This automatically be the
case if the device does not stretch the LOW period of the SCL signal. If such device does stretch the LOW period of the SCL signal, it must output the next data bit
to the SDA line trmax + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-Mode I2C-bus specification) before the SCL line is released.

Notes
43. When VDD remains in the range from 1.71 V to 1.9 V for more than 50 µs, the slew rate when moving from the 1.71 V to 1.9 V range to greater than 2 V must be
slower than 1 V/500 µs to avoid triggering POR. The only other restriction on slew rates for any other voltage range or transition is the SRPOWER_UP parameter.
44. If powering down in standby sleep mode, to properly detect and recover from a VDD brown out condition any of the following actions must be taken:
a.Bring the device out of sleep before powering down.
b.Assure that VDD falls below 100 mV before powering back up.
c.Set the No Buzz bit in the OSC_CR0 register to keep the voltage monitoring circuit powered during sleep.
d.Increase the buzz rate to assure that the falling edge of VDD is captured. The rate is configured through the PSSDC bits in the SLP_CFG register.
For the referenced registers, refer to the CY8C24x93 Technical Reference Manual . In deep sleep mode, additional low power voltage monitoring circuitry allows
VDD brown out conditions to be detected for edge rates slower than 1V/ms.
45. For USB mode, the VDD supply for bus-powered application should be limited to 4.35 V–5.35 V. For self-powered application, VDD should be 3.15 V–3.45 V.

Glossary
Crosspoint connection Connection between any GPIO combination via analog multiplexer bus.
Differential non-linearity Ideally, any two adjacent digital codes correspond to output analog voltages that are exactly
one LSB apart. Differential non-linearity is a measure of the worst case deviation from the
ideal 1 LSB step.
Hold time Hold time is the time following a clock event during which the data input to a latch or flip-flop
must remain stable in order to guarantee that the latched data is correct.
I2C It is a serial multi-master bus used to connect low speed peripherals to MCU.
Integral nonlinearity It is a term describing the maximum deviation between the ideal output of a DAC/ADC and
the actual output level.
Latch-up current Current at which the latch-up test is conducted according to JESD78 standard (at 125
degree Celsius)
Power supply rejection ratio (PSRR) The PSRR is defined as the ratio of the change in supply voltage to the corresponding
change in output voltage of the device.
Setup time Period required to prepare a device, machine, process, or system for it to be ready to
function.
SPI Serial peripheral interface is a synchronous serial data link standard.

The following Errata items apply to the CY8C24093/293/393/693 datasheet 001-86894.
1. DoubleTimer0 ISR
Problem Definition
When programmable timer 0 is used in “one-shot” mode by setting bit 1 of register 0,B0h (PT0_CFG), and the timer interrupt is
used to wake the device from sleep, the interrupt service routine (ISR) may be executed twice.
Parameters Affected
No datasheet parameters are affected.
Trigger Condition(S)
Triggered by enabling one-shot mode in the timer, and using the timer to wake from sleep mode.
Scope of Impact
The ISR may be executed twice.
Workaround
In the ISR, firmware should clear the one-shot bit with a statement such as “and reg[B0h], FDh
Fix Status
Will not be fixed
Changes
None

2. Missed GPIO Interrupt
Problem Definition
When in sleep mode, if a GPIO interrupt happens simultaneously with a Timer0 or Sleep Timer interrupt, the GPIO interrupt may
be missed, and the corresponding GPIO ISR not run.
Parameters Affected
No datasheet parameters are affected.
Trigger Condition(S)
Triggered by enabling sleep mode, then having GPIO interrupt occur simultaneously with a Timer 0 or Sleep Timer interrupt.
Scope of Impact
The GPIO interrupt service routine will not be run.
Workaround
The system should be architected such that a missed GPIO interrupt may be detected. For example, if a GPIO is used to wake
the system to perform some function, the system should detect if the function is not performed, and re-issue the GPIO interrupt.
Alternatively, if a GPIO interrupt is required to wake the system, then firmware should disable the Sleep Timer and Timer0.
Alternatively, the ISR’s for Sleep Timer and Timer0 should manually check the state of the GPIO to determine if the host system
has attempted to generate a GPIO interrupt.
Fix Status
Will not be fixed
Changes
None
3. Missed Interrupt During Transition to Sleep
Problem Definition
If an interrupt is posted a short time (within 2.5 CPU cycles) before firmware commands the device to sleep, the interrupt will be
missed.
Parameters Affected
No datasheet parameters are affected.
Trigger Condition(S)
Triggered by enabling sleep mode just prior to an interrupt.
Scope of Impact
The relevant interrupt service routine will not be run.
Workaround
None.
Fix Status
Will not be fixed
Changes
None

5. Wake-up fr om Sleep with Hardware I2C Address match on Pins P1[0], P1[1]
Problem Definition
I2C interface needs 20 ns hold time on SDA line with respect to falling edge of SCL, to wake-up from sleep using I2C hardware
address match event.
Parameters Affected
tHD;DAT increased to 20 ns from 0 ns
Trigger Condition(S)
This is an issue only when all these three conditions are met:
1) P1.0 and P1.1 are used as I2C pins,
2) Wakeup from sleep with hardware address match feature is enabled, and
3) I2C master does not provide 20 ns hold time on SDA with respect to falling edge of SCL.
Scope of Impact
These trigger conditions cause the device to never wake-up from sleep based on I2C address match event
Workaround
For a design that meets all of the trigger conditions, the following suggested circuit has to be implemented as a work-around. The
R and C values proposed are 100 ohm and 200 pF respectively.
Fix Status
Will not be fixed

6. I2C Port Pin Pull-up Supply Voltage
Problem Definition
Pull-up resistor on I2C interface cannot be connected to a supply voltage that is greater than 0.7 V of CY8C24093/293/393/693
VDD.
Parameters Affected
None.
Trigger Condition(S)
This problem occurs only when the I2C master is powered at a higher voltage than CY8C24093/293/393/693.
Scope of Impact
This trigger condition will corrupt the I2C communication between the I2C host and the CY8C24093/293/393/693 controller.
Workaround
I2C master cannot be powered at a supply voltage that is greater than 0.7 V compared to CY8C24093/293/393/693 supply voltage.
Fix Status
Will not be fixed
Changes
None
7. Port1 Pin Voltage
Problem Definition
Pull-up resistor on port1 pins cannot be connected to a voltage that is greater than 0.7 V higher than CY8C24093/293/393/693 VDD.
Parameters Affected
None.
Trigger Condition(S)
This problem occurs only when port1 pins are at voltage 0.7 V higher than VDD of CY8C24093/293/393/693.
Scope of Impact
This trigger condition will not allow CY8C24093/293/393/693 to drive the output signal on port1 pins, input path is unaffected by
this condition.
Workaround
Port1 should not be connected to a higher voltage than VDD of CY8C24093/293/393/693.

CY8C24193/493 Errata Summary
The following Errata items apply to the CY8C24193/493 datasheet 001-86894.
1. Wakeup from sleep may intermittently fail
Problem Definition
When the device is put to sleep in Standby or I2C_USB Mode and the bandgap circuit is refreshed less frequently than every 8 ms
(default), the device may not come out of sleep when a sleep-ending input is received.
Parameters Affected
None
Trigger Condition(S)
By default, when the device is in the Standby or I2C_USB sleep modes, the bandgap circuit is powered-up approximately every 8
ms to facilitate detection of POR or LVD events. This interval can be lengthened or the periodic power-up disabled to reduce sleep
current by setting the ALT_BUZZ bits in the SLP_CFG2 register or the Disable Buzz bit in the OSC_CR0 register respectively. If
the bandgap circuit refresh interval is set longer than the default 8 ms, the device may fail to wakeup from sleep and enter a locked
up state that can only be recovered by Watchdog Reset, XRES, or POR.
Scope of Impact
The trigger conditions outlined above may cause the device to never wakeup.
Workaround
Prior to entering Standby or I2C_USB sleep modes, do not lengthen or disable the bandgap refresh interval by manipulating the
ALT_BUZZ bits in the SLP_CFG2 register or the Disable Buzz bit in the OSC_CR0 register respectively.
Fix Status
This issue will not be corrected in the next silicon revision.

2. I2C Errors
Problem Definition
The I2C block exhibits occasional data and bus corruption errors when the I2C master initiates transactions while the device is
transitioning in to or out of sleep mode.
Parameters Affected
Affects reliability of I2C communication to device, and between I2C master and third party I2C slaves.
Trigger Condition(S)
Triggered by transitions into and out of the device’s sleep mode.
Scope of Impact
Data errors result in incorrect data reported to the I2C master, or incorrect data received from the master by the device. Bus
corruption errors can corrupt data in transactions between the I2C master and third party I2C slaves.
Workaround
Firmware workarounds are available in firmware. Generally the workaround consists of disconnecting the I2C block from the bus
prior to going to sleep modes. I2C transactions during sleep are supported by a protocol in which the master wakes the device prior
to the I2C transaction.
Fix Status
To be fixed in future silicon.
Changes
None
3. DoubleTimer0 ISR
Problem Definition
When programmable timer 0 is used in “one-shot” mode by setting bit 1 of register 0,B0h (PT0_CFG), and the timer interrupt is
used to wake the device from sleep, the interrupt service routine (ISR) may be executed twice.
Parameters Affected
No datasheet parameters are affected.
Trigger Condition(S)

4. Missed GPIO Interrupt
Problem Definition
When in sleep mode, if a GPIO interrupt happens simultaneously with a Timer0 or Sleep Timer interrupt, the GPIO interrupt may
be missed, and the corresponding GPIO ISR not run.
Parameters Affected

the system to perform some function, the system should detect if the function is not performed, and re-issue the GPIO interrupt.
Alternatively, if a GPIO interrupt is required to wake the system, then firmware should disable the Sleep Timer and Timer0.
Alternatively, the ISR’s for Sleep Timer and Timer0 should manually check the state of the GPIO to determine if the host system
has attempted to generate a GPIO interrupt.
