DS26303 Design Kit
BASIC OPERATION
This design kit relies upon several supporting files, which are available for downloading on our website at
The support files are used with an evaluation program called ChipView, which is available for download at
HARDWARE CONFIGURATION
Quick Start (Hardware Settings—Single Power Supply)

?
For single power-supply operation, short jumpers J18, J19, and J20 between the 3.3V pin and the VLIU pin.
This connects VDD of the DS26303 to the 3.3V supply on the design kit.
Ensure that the FLASH switch (SW3) is in the RUN position.
Ensure that the FPGA switch (SW5) is in the ON position.
Ensure that the SPI/PROM switch (SW7) is in the OFF position.
If using the serial port, connect a RS-232 serial cable from DS26303DK (J4) to the PC.
If using the USB port, connect a USB cable from DS26303DK (J3) to the PC.
Connect AC/DC adapter with an AC power source and the DS26303DK (J2). PWR LED should be on.
JTAG Configuration
The JTAG chain is controlled by the connector JTAG CON (J6) and two on-board switches: FLASH (SW3) and
ONCE/JTAG (SW4). Depending on the function, such as programming the internal microcontroller flash or
performing boundary scan operations, the JTAG CON connector can be used and the switches can be configured
to accomplish the desired task. For information on programming the internal flash of the on-board microcontroller,
refer to the MMC2107 microcontroller user manual and board schematic.
For most purposes, having the complete JTAG chain is sufficient. Figure 1 shows the complete chain as well as
what order the devices appear during boundary scan. Table 1 shows the pinout of the JTAG connector. Connect
any JTAG cable to the connector to perform all operations. Note the JTAG chain changes depending on the switch
SW4. The ONCE location of SW4 is used for programming the on-board microcontroller only.
