2. Get to know the hardware
2.1 Board description
The FRDM33771CSPEVB serves as a hardware evaluation tool in support of NXP's MC33771C device. The MC33771C is a battery cell controller that monitors up to 14 lithium-ion battery cells. It is designed for use in both automotive and industrial applications.
The device performs ADC conversion on the differential cell voltages and currents. It is also capable of battery charge coulomb counting and battery temperature measurements. The FRDM33771CSPEVB is an ideal platform for rapid prototyping of MC33771C-based applications that involve current, voltage and temperature sensing.
The FRDM33771CSPEVB supports standard SPI interface. The information is digitally transmitted to a microcontroller for processing.
2.2 Board features
- Standard SPI communication
- LED indicator for operation mode
- Cell-balancing resistors
- Cell sense input with RC filter
- 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 interface) to store user-defined calibration parameters
- Fault detection pin report
- Current measurement input via external shunt

2.4 Additional board support
Refer to UM11402, FRDM33771CSPEVB evaluation board user manual for additional details on the featured components.
3. Configure the hardware
The FRDM33771CSPEVB can be configured as a shield board connected to an S32K144EVB board.
When FRDM33771CSPEVB and the S32K144EVB are connected together, 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.
3.1 Battery emulator connection
The FRDM33771CSPEVB supports the use of a battery cell emulator such as NXP's BATT-14CEMULATOR board.
The BATT-14CEMULATOR is a 14-cell battery emulator board that provides an intuitive way to change the voltage across any of the 14 cells and four voltage outputs in order to emulate four external NTC. A minimum of 7 cells and a maximum of 14 cells can be monitored.
The emulator board can be connected to the FRDM33771CSPEVB connector X1 using the provided supply cable.
To exercise the FRDM33771CSPEVB in combination with the BAT-14CEMULATOR, a graphical user interface is available at https://www.nxp.com/webapp/Download?colCode=KIT33771C_V5_APPSP.
