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 FRDM33772CSPEVB evaluation board.

2.1 Board Description

The FRDM33772CSPEVB allows the user to exercise all the functions of the MC33772C battery controller cell.

It is stacked onto an S32K144EVB. SPI communication is done through connector K1 to K6. The FRDM33772CSPEVB is supplied when connected to a battery cell stack through connector J12. The S32K144EVB is supplied through its USB connection when connected to a PC.

2.2 Board Features

  • Standard SPI communication
  • LED indicator for operation mode
  • Cell-balancing resistors
  • Cell sense input with RC filter
  • General-purpose input/output (GPIO): digital I/O, wake-up inputs, convert trigger inputs, ratiometric analog inputs, analog inputs with absolute measurements
  • EEPROM (connected to the IC with I²C-bus interface) to store user-defined calibration parameters
  • Fault detection pin report
  • Current measurement input via external shunt

2.3 Board Components

Overview of the FRDM33772CSPEVB evaluation board.

Number Label Name Description
1 D7 VCOM LED Indicates whether the device is in normal mode or in low-power mode.
2 U2 24LC01BT-I/OT IC memory EEPROM.
3 U1 MC33772C Battery cell controller IC.

3. Configure Hardware

3.1 Configure Hardware

The FRDM33772CSPEVB can be configured as a shield board connected to an S32K144EVB board.

When both boards are connected together (see Figure 1), the SPI connector is directly connected with the MCU SPI pins. In this configuration, power is supplied to the S32K144EVB through a USB cable connected between the S32K144EVB board and a PC. No external power supply is required.

3.2 Battery Emulator Connection

The FRDM33772CSPEVB supports the use of a battery cell emulator such as NXP's BATT-6EMULATOR board and BATT-14AAAPACK.

The BATT-6EMULATOR is a 6-cell battery emulator board that provides an intuitive way to change the voltage across any of the 6 cells and four voltage outputs in order to emulate four external NTC.

The emulator board can be connected to the FRDM33772CSPEVB connector J12 using the provided supply cable.

To exercise the FRDM33772CSPEVB in combination with the BATT-6EMULATOR, a graphical user interface is available at MC33771C/MC33772C (Battery Cell Controller) Evaluation GUI.
