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 P3A1604UK-ARD board.

2. Get to Know the Hardware

As default, P3A1604UK Port A is configured to operate at 1.8 V while Port B is configured to operate at 3.3 V via jumper settings shown in Table 1. Port A I²C/I3C interface is available at J21 and J24, while Port B I²C/I3C interface is available on J26 and J27.

Port A signals are routed to the Arduino® header (J1) and MCU/Aardvark header (J18) allowing for easy connection to a I²C/I3C controller (MCU).

Port B signals are connected to one on-board 8-bit I²C GPIO expander (PCA9538PW), and one I3C temperature sensor (P3T1750DP). The factory default I²C/I3C addresses for these device are listed in Table 2. The user can also connect their own I²C/I3C target devices to the Port B I²C/I3C interface headers (J26, J27).

GPIO0 and GPIO1 on the PCA9538PW are connected to a pair of LEDs (blue and red). The user can turn on, turn off, or blink the LED by communicating with the PCA9538PW via I²C.

P3A1604UK can be enabled/disabled via J28. It is enabled by default.

P3A1604UK-ARD evaluation board is powered via a USB micro-B connector, J2. There are on-board LDOs to convert 5 V from the micro-B connector to other power rails to provide power to VCCA, VCCB other components on the board. VCCA can be configured through J7, J8, J9. VCCB can be configured through J11, J12, J13.

The P3A1604UK-ARD evaluation board is designed to be mated and controlled by a MCU board with standard Arduino® headers. The P3A1604UK is then powered by the available 5 V rail from the MCU board. Table 3 lists all interface signals the MCU needs to communicate with the P3A1604UK-ARD.

2.2 Board Description

The P3A1604UK is a quad-bidirectional voltage level translator with auto direction sensing, that enables bidirectional voltage level translation. It includes a reference supply VCCA for port A and VCCB for port B. The supply voltage of VCCA and VCCB is between 0.72 V to 3.63 V. Pins A1 to A4 are referenced to VCCA, pins B1 to B4 are referenced to VCCB. Pin OE is used as the device enable input and is referenced to VCCA.

P3A1604UK can be used for both open-drain and push-pull application which allows for I3C bus and other applications like I²C-bus, SMBus and SPI protocols. Refer to the following figure to find the location of connectors and jumpers on the evaluation board.

3. Configure Hardware

3.1 Configure Hardware

  1. Unpack the board and power it with the micro-B USB cable
  2. Connect a 1.8 V I3C controller to Port A via J1 (Arduino) or J18 (MCU/Aardvark). See schematic for wiring connection. By default, both port A has on-board 2.2 K pull-ups. If the pull-ups are already present on the I3C controller board, then the on-board pull-ups can be disabled via J20 and J23 (see Table 1)
