1. Out of the Box

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 and Packing List

The SC18IS604-EVB contents include:

  • Assembled and tested evaluation board in an anti-static bag

1.2 Additional Requirements

  • External power supply
  • External host system with SPI controller

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.

3. Configure Hardware

3.1 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
