Getting Started with the UJA1163A Evaluation Board

This page will assist you in learning about your UJA1163A Evaluation Board.

Get to Know the Hardware

2.1 Board Description

The UJA1163A-EVB evaluation boards are designed to facilitate the testing and evaluation of UJA1163A product features in a variety of microcontroller IO interface environments. All MCU interface signals can be accessed in two ways: at a header row on the top side and also at header rows on the bottom side that can be plugged directly into many NXP MCU evaluation boards.

The UJA1163A-EVB evaluation boards are designed to be compatible with the S32K1xx evaluation board series from NXP and to support the use of standard software development tools and drivers.

2.2 Board Components

Board dimensions are 45.1 mm × 58.4 mm. Only components needed to support basic UJA1163A functionality are included. All boards contain circuitry for reverse polarity protected battery supply, BAT and V1 signal status LEDs and CAN bus termination. The board also provides several header rows (2.54 mm pitch) for connecting MCU interface and application signals.


Configure the hardware

To connect the UJA1163A-EVB to a CAN network, complete the following procedure.

The following conditions must be met before powering up the system with a 12 V supply:

  1. Connect boards in the ECU to a common GND
  2. Connect pin CTS (J3-03, J4-09) to an MCU IO input pin
  3. Connect pin STBN/SLPN (J3-06, J4-09) to an MCU IO output pin
  4. Connect TXD/RXD (J3-01/J3-02, J4-18/J4-20) pins to the MCU CAN controller TXD/RXD pins
  5. Connect CANH and CANL (J1-01/J1-02) to the CAN bus twisted-pair cables
  6. Connect RST (J3-09, J5-05) on the UJA1163A-EVB to the MCU CAN controller RSTN pin
  7. Connect V1 (J3-08, J5-03) on the UJA1163A-EVB to the MCU supply unit

Once the above steps have been completed, the ECU/EVB can be powered up using an external battery supply. The UJA1163A-EVB starts up in Standby mode, and then switches between Standby/Sleep modes and Normal mode depending on the level on pin STBN/SLPN.
