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.

2.2 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.

Configure Hardware
3.1 Configure the Hardware
To configure the hardware, complete the following procedure:
- Plug battery simulator and low-voltage cables to the board
-
Connect battery simulator cable to a power supply #1 (10 to 60 VDC, current limitation 100 mA). The text labels on the bottom of the board indicate pin positions
Caution:Incorrect connections of the power and ground wires damage the board -
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
Caution:Incorrect connections of the power and ground wires damage the board - 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
- Connect multilink to the JTAG port next to the MCU
- Launch S32 Design Studio for ARM
- Import example software project, launch, and download/debug in S32 Design Studio for ARM to evaluate this board
