General Description
The MAXQ615 evaluation kit (EV kit) provides a proven
platform for conveniently evaluating the capabilities of
the MAXQ615 low-power, 16-bit, RISC microcontroller
targeted for battery-powered applications. The EV kit
includes a MAXQ615 EV kit board, example software,
USB-to-JTAG interface board, 10-pin JTAG interface
cable, and a standard A-to-mini-B USB cable for con-
necting to a personal computer. The EV kit board, which
provides pin headers providing access to the proces-
sor’s I/O port pins, a 5V power-supply input, pushbutton
switches for user input, and an on-board SPI ADC and
I2C temperature sensor for demonstration purposes.
The EV kit provides a complete, functional system ideal
for developing and debugging applications as well as
evaluating the overall capabilities of the MAXQ615 RISC
processor.

Detailed Description
This EV kit should be used with the following documents:
• MAXQ615ICdatasheet
• MAXQ615user’sguide
• MAXQ615EVkitdatasheet
These documents are included on the MAXQ615 EV kit
CD, along with additional documentation and application
notes. For the latest versions of the documents listed
above, go to www.maximintegrated.com/MAXQ615.
This document includes full schematics for the EV kit.
Descriptions of the major sections and functions of the
board follows.
Power Supply
The MAXQ615 EV kit can be powered in several ways.
The board can be powered from the USB-to-JTAG adapt-
er. The adapter provides a +5V DC supply. From this, an
on-board linear regulator (U1) regulates the +3.3V VDD
power rail that is used by the MAXQ615.
If the MAXQ615 kit is “free-running,” that is, if you are run-
ning an application that has been previously loaded into
the MAXQ615, and you do not need to use the loader or
debugger, the board may be powered by a 5V DC wall
supply connected to plug J1. The supply must be center
post positive, DC 5V regulated, with a 250mA minimum
capacity.
By removing jumper JU1 and connecting a power sup-
ply in its place, it is also possible to power the MAXQ615
from a DC bench supply or other regulated power
source. In this case, any power-supply voltage compat-
ible with the device(s) that will be powered may be used;
refer to the MAXQ615 IC data sheet for more details on
the allowable range for the power supply.
Reset Pushbutton
Pushbutton SW3 can be used to manually reset the MAXQ615.

Serial ADC
The EV kit board includes a MAX1118 2-channel serial
ADC (U2). By connecting the appropriate jumpers, the
ADC can be connected to the MAXQ615, and is used
to demonstrate the microcontroller’s SPI communication
interface. Each of the two ADC channels can be con-
nected to the cathode of an on-board LED, and can be
used to measure the voltage drop across the LED. The
CD included with this EV kit includes sample code to
demonstrate how to interact with the ADC.
I2C Temperature Sensor
The EV kit board includes a DS1775 I2C temperature
sensor (U3). By connecting the appropriate jumpers, the
temperature sensor can be connected to the MAXQ615,
and is used to demonstrate the microcontroller’s I2C
communication interface. The CD included with this EV
kit includes sample code to demonstrate how to interact
with the temperature sensor.
GPIO Pushbuttons and Indicator LEDs
The two pushbuttons on the EV kit board can be con-
nected to the MAXQ615 GPIO pins P1.0 and P1.1 by
closing the associated jumper. See Table 1 for a descrip-
tion of the jumpers. If the pushbutton is pressed, it will
pull the attached port pin low. The label indicating which
port pin is tied to the switch is found on the board next to
the switch. Switch SW2 pulls pin P1.0 (P10 label) low and
switch SW1 pulls pin P1.1 low.
The indicator LEDs (D5 and D6) next to each switch can
also be connected to the port pin by closing the associ-
ated jumper (as detailed in the jumper table). The LED
will be illuminated if either the GPIO pin connected to it is
driven low, or the pushbutton switch is pressed.
Jumper Function List
Table 1 details the functions of the configurable jumpers
on the EV kit board. Settings in the table marked with “*”
indicate jumper placements that should be used for most
normal operation (default settings).
Table 1. Jumper Functions
JUMPER SETTING EFFECT OF SETTING
JU1
Open
No on-board supply is connected to the VDD rail. To operate the EV kit, an external bench supply
must be connected to JU1.2 or one of the VDD test points. Refer to the MAXQ615 IC data sheet for
acceptable operating range information for the VDD supply.
*Closed
The +3.3V output from the on-board linear regulator (U1) is connected to the VDD rail. This supply
will be used to power the MAXQ615 (as long as JU2 is closed), as well as the demo components
U2 and U3 and the LEDs D5 and D6.
JU2 Open No power is provided to the MAXQ615. This position should only be used when connecting a
current meter between JU2.1 and JU2.2 to measure power consumption by the MAXQ615.
*Closed The VDD pin on the MAXQ615 is connected to the on-board VDD power supply rail.
JU3
Open
The 5V pin on the JTAG cable is not connected to the on-board linear regulator supply input. If this
position is used, then either a 5V external supply must be connected to J1 or a bench supply must
be connected to JU1.2 or a VDD test point (with JU1 open)
Closed The MAXQ615 EV kit may be powered directly through the USB-to-JTAG adapter’s 5V supply (from
the USB bus supply)
JU4
Open No effect
Closed The channel 1 input (CH1) on the ADC U2 is connected between LED D5 and R6 (see the EV kit
schematic). This can be used to measure the diode drop across D5, for demonstration purposes.
JU5
Open No effect
Closed The channel 0 input (CH0) on the ADC U2 is connected between LED D6 and R8 (refer to the kit
schematic). This can be used to measure the diode drop across D6, for demonstration purposes.
JU6
Open No effect
Closed
The “start conversion on falling edge” pin on the MAX1118 (U2) is connected to pin P0.3 on the
MAXQ615. Refer to the MAX1118 IC data sheet for more information on initiating A/D conversions
and reading conversion results.

MAXQ615.
JU8
Open No effect
Closed The SCLK pin on the MAX1118 is connected to the SPI 0 interface pin SCLK (P0.2) on the
MAXQ615.
JU9
Open No effect
Closed Connects the SDA pin on the I2C temperature sensor (DS1775, U3) to the I2C SDA pin (P1.3) on
the MAXQ615. Also connects the I2C bus pullup resistor (R3) to the SDA pin on the MAXQ615.
JU10
Open No effect
Closed Connects the SCL pin on the I2C temperature sensor (DS1775, U3) to the I2C SCL pin (P1.2) on
the MAXQ615. Also connects the I2C bus pullup resistor (R4) to the SCL pin on the MAXQ615.
JU11
Open No effect
Closed Allows the green LED D5 to be controlled using the port pin P1.1 (driving the port pin low lights the
LED). Also, pressing SW1 will both drive P1.1 low and cause the LED to light.
JU12
Open No effect
Closed Allows the green LED D6 to be controlled using the port pin P1.0 (driving the port pin low lights the
LED). Also, pressing SW2 will both drive P1.0 low and cause the LED to light.
