1. Get Started

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 UJA1168AFEVB evaluation board.

2.1 Board Description

Board dimensions are 45.1 mm × 58.4 mm. Only components needed to support basic UJA1168AF functionality are included. All boards contain circuitry for reverse polarity protected battery supply, BAT and V1 signal status LEDs, and CAN bus termination. Wake-up circuitry is also included since the UJA1168AF device supports sleep mode. The board also provides several header rows (2.54 mm pitch) for connecting MCU interface and application signals.

3.1 Configure Hardware

To connect the UJA1168AF-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:

Connect boards in the ECU to a common GND
Connect SPI pins to the MCU SPI master:
1. SDO (J3-03, J4-09) → MISO
2. SDI (J3-04, J4-07) → MOSI
3. SCK (J3-05, J4-11) → SCK
4. SCSN (J3-06, J4-05) → CS
Connect TXD/RXD (J3-01/J3-02, J4-18/J4-20) pins to the MCU CAN controller TXD/RXD pins
Connect RSTN (J9-09/J5-05) to the MCU reset pin
Connect CANH and CANL (J1-01/J1-02) to the CAN bus twisted-pair cables
Connect V1(J3-08, J5-03) to the MCU supply unit
Connect INH (J3-10) on the UJA1168AF-EVB to the control/enable pin on the ECU supply unit (optional)

Once the above steps have been completed, the ECU/EVB can be powered up using an external battery supply. The UJA1168AF-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.
