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 learning about how to set up the RD33771CNTREVM board.

2. Know the Hardware

2.1 Board Features

  • Four BCCs on one board
  • Each BCC can measure voltage for up to 14 battery cells with high accuracy
  • Each BCC has 6-channel temperature sensing
  • The first BCC has a current-sensing point, could connect an external shunt resistor for current measurement
  • Capacitor or TPL isolation communication on the board
  • TPL isolation for off-board communication
  • Cell balancing current set to 100 mA, expandable up to 300 mA by adding CB resistors
  • Low-cost SBC and MCU as BCC management
  • One channel CAN interface
  • JTAG debugging interface
  • High EMC performance: passed BCI 200 mA, CE CISPR class 3

2.2 Board Description

The RD33771CNTREVM provides a solution for a centralized and distributed architecture for lithium-ion battery management in automotive applications. This board allocates four MC33771C devices controlled by one MCU. The MCU could be bypassed and stacked to a long daisy chain for a flexible BMS architecture.

Each BCC can measure lithium batteries having 7 to 14 cells each. The BCCs communicate by TPL daisy chain or capacitor isolation. The MCU is supplied by an SBC that is powered by a 12 VDC power source.

3. Configure Hardware

3.1 Configure the Hardware

RD33771CNTREVM HW Configuration

RD33771CNTREVM HW Configuration

To configure the hardware, complete the following procedure:

  1. Plug battery simulator and low-voltage cables to the board
  2. Connect battery simulator cable to power supply #1 (10 to 60 VDC, current limitation 100 mA). The text labels on the bottom of the board indicate pin positions
  3. Connect the low-voltage cable to power supply #2 (12 VDC, current limitation 200 mA). The text labels on the bottom of the board indicate pin positions
    • If successfully supplied, the LED on the board is lit up. The power consumption for power supply #1 is about 40 mA, and for power supply #2, the consumption is about 50 mA
    • If no MCU program is downloaded or the MCU power is OFF, the LED on each BCC turns OFF after 60 seconds
  4. Connect multilink to the JTAG port next to the MCU
  5. Launch S32 Design Studio for ARM
  6. Import example software project, launch, and download/debug in S32 Design Studio for ARM to evaluate this board

4. Install Software

4.1 Installing the Software

  1. Download the S32 Design Studio IDE for ARM (Version 2018.R1 is recommended)
  2. Open the installer, then follow the instructions in the setup wizard
  3. Get the example project from RD33771CNTREVM webpage
  4. Start development with an example source code

4.2 Success

Start embedded application development.
