The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost and improved performance in powering state-of-the-art systems.
This page will guide you through the process of setting up and using the SC18IS604-EVB evaluation board.
1.1 Kit contents/packing list
The SC18IS604-EVB contents include:

- External host system with SPI controller
Get to know the hardware
2.1 Board features
- 7-pin 100 mil spacing SPI interface header (JP1)
- On-board I2C EEPROM and LED blinker which can be directly accessed by the external SPI controller via the SC18IS604
- 4-pin 100 mil spacing I2C interface header (JP4) to allow other I2C devices to be connected to the evaluation board to be accessed via the SC18IS604
2.2 Board description
The SC18IS604-EVB board is designed to be connected to an external SPI controller via a 7-pin male (JP1) header. The SC18IS604-EVB evaluation board has an on-board I2C target serial EEPROM and an I2C target LED blinker, which can be directly accessed by the external SPI controller via SC18IS604. The external SPI controller can write, read and program the serial EEPROM/LED blinker without requiring an I2C target to be connected to the board
The 3V3 power for the evaluation board should be supplied via this I2C interface header as well.
The SC18IS604-EVB evaluation board also has an I2C interface header (JP4) to allow other I2C target devices to be connected to the SC18IS604-EVB evaluation board. These I2C target devices can be accessed directly by the SPI controller via the SC18IS604 SPI to I2C bridge.
2.3 Board components
Overview of the SC18IS604-EVB evaluation board
Configure the hardware
- Connect 3.3 V to JP1 pin 5
- Connect external SPI controller to JP1 pin 6 (-CS), pin 5 (MISO), pin 4 (MOSI), pin 3 (SCLK)
- Connect ground to JP1 pin 2
- If interrupt is supported, connect interrupt signal to JP1 pin 1
- SC18IS604 is reset up on POR but can be reset externally via the on-board switch SW1
- The board is powered and SC18IS604 can be accessed by the SPI controller
