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 SC18IM704-EVB evaluation board.

1.1 Kit Contents and Packing List

The SC18IM704-EVB contents include:

  • Assembled and tested evaluation board in an anti-static bag
  • Wurth ferrite core
  • Instruction of how to use the ferrite core

1.2 Additional Requirements

2.1 Board Features

  • 9-pin D-SUB RS-232 style UART interface port (J1)
  • 2-pin CMOS level UART interface (JP5). Refer to SC18IM704 board user manual on how to select JP5 for UART interface
  • On-board I²C EEPROM and I²C blinker which can be directly accessed by the external UART via the SC18IM704
  • 4-pin 100 mil spacing I²C interface header (J2) to allow other I²C devices to be connected to the evaluation board to be accessed via the SC18IM704

2.2 Board Description

The SC18IM704 evaluation board is designed to be connected to an external UART via a 9-pin RS-232 connector (J1). The SC18IM704 evaluation board has an on-board I²C target serial EEPROM and an I²C target LED blinker, which can be directly accessed by the external host UART via SC18IM704. The external host UART can write, read, and program the serial EEPROM/LED blinker without requiring an I²C target to be connected to the board.

The SC18IM704 evaluation board also has a I²C interface header (JP2) to allow other I²C target devices to be connected to the evaluation board. These I²C target devices can be accessed directly by the external host UART via the SC18IM704 UART to I²C bridge.

The power for the evaluation board is provided via the micro-B USB (J2), or via the I²C interface header (J2).

The SC18IM704 evaluation board 9-pin RS-232 port (J1) is intended to be the main UART interface to the host’s UART, but UART TX and RX CMOS level signals are available on JP5. When JP5 is used to interface to the host’s UART then the jumper on JP4 should be removed to remove power from the RS-232 line driver.
