These devices are designed to replace multiple traditional MCU-based system components with a low cost single-chip programmable component. A PSoC device includes configurable blocks of analog and digital logic, and programmable interconnect. This architecture allows you 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. Digital System The digital system consists of four digital PSoC blocks. Each block is an 8-bit resource that can be used alone or combined with other blocks to form 8, 16, 24, and 32-bit peripherals, which are called user modules. Digital peripheral configurations include: PWMs (8- and 16-bit) PWMs with dead band (8- and 16-bit) The PSoC architecture, as shown in Figure 1, consists of four main areas: the Core, the System Resources, the Digital System, and the Analog System. Configurable global bus resources allow the combining of all device resources into a complete custom system. Each PSoC device includes four digital blocks. Depending on the PSoC package, up to two analog comparators and up to 16 GPIO are also included. The GPIO provide access to the global digital and analog interconnects. Counters (8- to 32-bit) Timers (8- to 32-bit) UART 8-bit with selectable parity (up to two) SPI master and slave I2C slave, master, multi-master (one available as a system resource) PSoC Core Cyclical redundancy checker/generator (8-bit) IrDA (up to two) Pseudo random sequence generators (8- to 32-bit) 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 internal main oscillator (IMO), and internal low-speed oscillator (ILO). The CPU core, called the M8C, is a powerful processor with speeds up to 24 MHz. The M8C is a four MIPS 8-bit Harvard-architecture microprocessor. System Resources provide additional capability, such as digital clocks or I2C functionality for implementing an I2C master, slave, MultiMaster, an internal voltage reference that provides an absolute value of 1.3 V to a number of PSoC subsystems, an SMP that generates normal operating voltages off a single battery cell, and various system resets supported by the M8C. The digital system consists of an array of digital PSoC blocks, which can be configured into any number of digital peripherals. The digital blocks can be connected to the GPIO through a series of global bus that can route any signal to any pin. This frees designs from the constraints of a fixed peripheral controller. The digital blocks can be connected to any GPIO through a series of global bus that can route any signal to any pin. The busses also allow for signal multiplexing and performing logic operations. This configurability frees your designs from the constraints of a fixed peripheral controller. Digital blocks are provided in rows of four, where the number of blocks varies by PSoC device family. This provides an optimum choice of system resources for your application. Family resources are shown in Table 1 on page 5. Figure 1.

Analog peripherals are very flexible and may be customized to support specific application requirements. Some of the more common PSoC analog functions (most available as user modules) are: System resources, some of which listed in the previous sections, provide additional capability useful to complete systems. Additional resources include a switch mode pump, low voltage detection, and power on reset. The merits of each system resource are. Analog-to-digital converters (single or dual, with 8-bit or 10-bit resolution) Pin-to-pin comparators (one) Single-ended comparators (up to 2) with absolute (1.3 V) reference or 8-bit DAC reference 1.3 V reference (as a system resource) In most PSoC devices, analog blocks are provided in columns of three, which includes one CT (continuous time) and two SC (switched capacitor) blocks. The CY8C21x23 devices provide limited functionality Type "E" analog blocks. Each column contains one CT block and one SC block. The number of blocks on the device family is listed in Table 1 on page 5. Figure 2. CY8C21x23 Analog System Block Diagram Digital clock dividers provide three customizable clock frequencies for use in applications. The clocks can be routed to both the digital and analog systems. Additional clocks can be generated using digital PSoC blocks as clock dividers. The I2C module provides 100 and 400 kHz communication over two wires. Slave, master, and multi-master modes are all supported. LVD interrupts can signal the application of falling voltage levels, while the advanced POR (power on reset) circuit eliminates the need for a system supervisor. An internal 1.3 V voltage reference provides an absolute reference for the analog system, including ADCs and DACs. An integrated switch mode pump (SMP) generates normal operating voltages from a single 1.2 V battery cell, providing a low cost boost converter.

Document Number: 38-12022 Rev. AC Page 5 of 47 CY8C21123/CY8C21223/CY8C21323 Development Tool Selection Software PSoC Designer At the core of the PSoC development software suite is PSoC Designer. Utilized by thousands of PSoC developers, this robust software has been facilitating PSoC designs for years. PSoC Designer is available free of charge at http://www.cypress.com. PSoC Designer comes with a free C compiler. PSoC Designer Software Subsystems You choose a base device to work with and then select different onboard analog and digital components called user modules that use the PSoC blocks. Examples of user modules are ADCs, DACs, Amplifiers, and Filters. You configure the user modules for your chosen application and connect them to each other and to the proper pins. Then you 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 allows for changing configurations at run time. Code Generation Tools PSoC Designer supports multiple third-party C compilers and assemblers. The code generation tools work seamlessly within the PSoC Designer interface and have been tested with a full range of debugging tools. The choice is yours. Assemblers. The assemblers allow assembly code to be merged 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 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. Document Number: 38-12022 Rev. AC 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 the designer to read and program and read and write data memory, read and write I/O registers, read and write CPU registers, set and clear breakpoints, and provide program run, halt, and step control. The debugger also allows the designer to create a trace buffer of registers and memory locations of interest. In-Circuit Emulator A low cost, high functionality In-Circuit Emulator (ICE) is available for development support. This hardware has the capability to program single devices. The emulator consists of a base unit that connects to the PC by way of 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 (24MHz) operation. Standard Cypress PSoC IDE tools are available for debugging the CY8C20x36A/66A family of parts. However, the additional trace length and a minimal ground plane in the Flex-Pod can create noise problems that make it difficult to debug the design. A custom bonded On-Chip Debug (OCD) device is available in a 48-pin QFN package. The OCD device is recommended for debugging designs that have high current and/or high analog accuracy requirements. The QFN package is compact and is connected to the ICE through a high density connector. PSoC Programmer Flexible enough to be used on the bench in development, yet suitable for factory programming, PSoC Programmer works either as a standalone programming application or it can operate directly from PSoC Designer. PSoC Programmer software is compatible with both PSoC ICE-Cube in-circuit emulator and PSoC MiniProg. PSoC programmer is available free of charge at http://www.cypress.com/psocprogrammer. Page 6 of 47 CY8C21123/CY8C21223/CY8C21323 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 by lowering inventory costs. These configurable resources, called PSoC Blocks, have the ability to implement a wide variety of user-selectable functions. Organize and Connect The PSoC development process can be summarized in the following four steps: 1. Select User Modules 2. Configure User Modules 3. Organize and Connect 4. Generate, Verify, and Debug When you are ready to test the hardware configuration or move on to developing code for the project, you 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 application programming interfaces (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. Select Components PSoC Designer provides a library of pre-built, pre-tested hardware peripheral components called "user modules." User modules make selecting and implementing peripheral devices, both analog and digital, simple. Configure Components Each of the User Modules 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 8 bits of resolution. The user module parameters permit you to 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 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 you may need to successfully implement your design. Document Number: 38-12022 Rev. AC You build signal chains at the chip level by interconnecting user modules to each other and the I/O pins. You perform the selection, configuration, and routing so that you have complete control over all on-chip resources. Generate, Verify, and Debug A complete code development environment allows 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 (access 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 and allows you to define complex breakpoint events that include monitoring address and data bus values, memory locations and external signals.

AC Page 40 of 47 CY8C21123/CY8C21223/CY8C21323 Glossary (continued) microcontroller An integrated circuit chip that is designed primarily for control systems and products. In addition to a CPU, a microcontroller typically includes memory, timing circuits, and IO circuitry. The reason for this is to permit the realization of a controller with a minimal quantity of chips, thus achieving maximal possible miniaturization. This in turn, reduces the volume and the cost of the controller. The microcontroller is normally not used for general-purpose computation as is a microprocessor. mixed-signal The reference to a circuit containing both analog and digital techniques and components. modulator A device that imposes a signal on a carrier. noise 1. A disturbance that affects a signal and that may distort the information carried by the signal. 2.

Or when devices are cascaded in width, the slave device is the one that allows another device to control the timing of data exchanges between the cascaded devices and an external interface. The controlling device is called the master device. SRAM An acronym for static random access memory. A memory device where you can store and retrieve data at a high rate of speed. The term static is used because, after a value is loaded into an SRAM cell, it remains unchanged until it is explicitly altered or until power is removed from the device. SROM An acronym for supervisory read only memory. The SROM holds code that is used to boot the device, calibrate circuitry, and perform Flash operations. The functions of the SROM may be accessed in normal user code, operating from Flash. stop bit A signal following a character or block that prepares the receiving device to receive the next character or block. synchronous 1. A signal whose data is not acknowledged or acted upon until the next active edge of a clock signal. 2. A system whose operation is synchronized by a clock signal. tri-state A function whose output can adopt three states: 0, 1, and Z (high-impedance). The function does not drive any value in the Z state and, in many respects, may be considered to be disconnected from the rest of the circuit, allowing another output to drive the same net. UART A UART or universal asynchronous receiver-transmitter translates between parallel bits of data and serial bits. user modules Pre-build, pre-tested hardware/firmware peripheral functions that take care of managing and configuring the lower level Analog and Digital PSoC Blocks. User Modules also provide high level API (Application Programming Interface) for the peripheral function. user space The bank 0 space of the register map.
