2.1 Board Features

The table below describes the board features of NAFE33352-UIOM.

Table: Board features

Device Description Location
Universal analog input/output (AIO) software (SW)-configurable AIO-analog front end (AFE) NAFE33352 U2
Single-pole single-throw (SPST) analog switches Switches U8 and U9
Linear drop-out (LDO) regulator LDO U4
High-voltage, charge pump DC-DC converter Charge pump U3
Quad-channel digital isolators Digital isolator U6, U5 and U7

2.2 Board Description

NXP’s NAFE33352-UIOM platform is a deployment-ready solution that helps engineers validate analog accuracy and diagnostics before scaling to production. This compact board (90 mm x 50 mm) integrates seamlessly with NXP MCX-N microcontroller (MCU) boards via Arduino connectors, offering plug-and-play flexibility for rapid prototyping.

Key features include:

  • Universal analog inputs for voltage, current, resistance temperature detector (RTD) and thermocouple sensing
  • Analog output up to ±12.5 V and ±25 mA for precise actuation
  • Built-in calibration and diagnostics to reduce scale-up risk
  • NAFE graphical user interface (GUI) and driver packs for fast configuration and development

NAFE33352 AFE integrates a high-resolution sigma-delta analog-to-digital converter (ADC) for precise sensing and digital-to-analog converter (DAC) for accurate actuation. NAFE33352 enables seamless interaction between sensors and actuators in closed-loop systems. This integration reduces the need for multiple discrete components, saving board space and simplifying design. NAFE33352 offers premium performance without compromise, helping engineers accelerate development and optimize reliability.

NAFE33352 offers superior accuracy and a highly integrated architecture, supporting both analog input and analog output in a single device. A GUI for this NAFE33352-UIOM platform allows the user to easily navigate the different functions of the driver. The IC communicates to the host via the industry-standard serial peripheral interface (SPI)-bus port. The evaluation software runs on Microsoft Windows 7, 8 and 10 PC platforms.

3. Plug It In

3.1 NAFE33352-UIOM Evaluation with NAFE33352-UIOM GUI

This section provides NAFE33352-UIOM installation requisites and instructions to install the same.

3.2 Installing the Software for GUI Operation

Download and install the NAFE33352-UIOM GUI software.

3.3 NAFE33352-UIOM Applications

The GUI provides NAFE33352-UIOM example codes and a detailed overview about hardware and software steps to evaluate NAFE33352-UIOM.

Follow the steps given below to install the NAFE33352-UIOM GUI.

  1. Running the installer application begins the process and click Next
  2. Select the installation location by clicking browse and select the user for NAFE33352-UIOM by selecting Everyone/Just me and click Next
  3. After confirming the message that now appears on the dialog box and click Next to begin the installation
  4. After the installation is complete, a dialog box displays the Installation Complete message and Click Close to close the dialog box
  5. After the installation is complete, check the NAFE33352-UIOM GUI guide to configure NAFE33352 and run different applications (For running on-board RTD applications, a few hardware modifications are needed)
  6. Remove resistor R39 and cut the trace connected to pin 13 of U7

Note: When using an external -15 V supply, the polarity of diode D9 must be reversed for proper operation.

For full installation instructions, including images of the steps, refer to chapter 7 of NAFE33352-UIOM Analog Sensing and Control Platform User Manual

4.1 Build and Load

The NAFE33352 Arduino UIOM kit includes the NAFE33352 evaluation board, an FRDM-MCXN 947 and a USB cable.

4.2 Configuring the Hardware

To set up the hardware, perform the below steps:

  1. Firmly connect the NAFE33352 Arduino UIOM board to the FRDM MCXN-947 evaluation board using the Arduino connectors
  2. To connect both boards, slide J8, J9, J10 and J11 male connectors at the bottom side of the NAFE33352 (AFE) evaluation board into the appropriate female connectors on the FRDM MCX-N 947 evaluation board
  3. Connect an adapter supply in the +7 V to +15 V range on J6 (an approximately 0.4 V accounts for the voltage drop across the Schottky diode for reverse polarity protection and voltage drop across the 5 Ω resistor because of the supply current flowing into the pin of the device)
  4. Use a USB to uUSB to connect the PC (USB) to the FRDM MCXN-947

For full installation instructions, including images of the steps, refer to chapter 6.4 of NAFE33352-UIOM Analog Sensing and Control Platform User Manual.
