Getting Started with the UJA1164A Evaluation Board

This page will assist you in learning about your UJA1164A Evaluation Board.

Get to Know the Hardware

2.1 Board Description

The UJA1164A-EVB evaluation boards are designed to facilitate the testing and evaluation of UJA1164A 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 UJA1164A-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

Overview of the PCT2075DP-ARD evaluation board

Board dimensions are 45.1 mm × 58.4 mm. Only components needed to support basic UJA1164A 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 UJA1164A-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 SPI pins to the MCU SPI master:
    • SDO (J3-03, J4-09) → MISO
    • SDI (J3-04, J4-07) → MOSI
    • SCK (J3-05, J4-11) → SCK
    • SCSN (J3-06, J4-05) → CS
  3. Connect TXD/RXD (J3-01/J3-02, J4-18/J4-20) pins to the MCU CAN controller TXD/RXD pins
  4. Connect RSTN (J9-09/J5-05) to the MCU reset pin
  5. Connect CANH and CANL (J1-01/J1-02) to the CAN bus twisted-pair cables
  6. Connect V1(J3-08, J5-03) 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 UJA1164A-EVB starts up in Forced Normal mode (if MTP is not configured) or Standby mode (if MTP configured), awaiting commands from the MCU via the SPI interface.
