REV. 1.0.0 XRA1403/1405 EVALUATION BOARD USERS MANUAL INTRODUCTION This users manual is for the XRA1403/1405 16-bit evaluation board. Table 1 shows the different devices and packages that the evaluation board supports. This users manual will describe the hardware setup required to operate the different packages. 1.0 QUICK START To verify communication with the GPIO expander, the following steps are recommended: 1.1 Connect external +5V power supply to J8 pin 1 1.2 Connect J12 pin 13 and 14 to ground of external power supply 1.3 Connect to MCU SPI interface for: SPI clock (SCK SCL signal at J5 pin11) SO (SO SPI signal at J5 pin17) SI (SI SPI signal at J5 pin21) CS (CS SPI signal at J5 pin19) 1.4 From the MCU, write the following registers: GCR1 = 0x00 GCR2 = 0x00 If the LEDs turn on, the communication with the GPIO expander is successful. To disable connection to LEDs, remove jumpers on J28, J29, J30 and J31. Connect to external inputs or outputs at J3 and J4. 2.0 HARDWARE SETUP 2.1 Packages description The evaluation board supports all 4 packages of the XRA1403 and XRA1405. The ordering part number, package and location on the board is shown below in Table 1. Table 2 lists the evaluation board ordering part numbers.
