48V battery is widely used in automotive, electric vehicles and energy storage. In the BMS system, except for the front-end analog sampling chip, MCU is the core control component, responsible for the communication between SOC/SOH algorithm and system. In that case MCU is required to be equipped with high-performance and rich peripherals.

Feature analysis:
-This device is based on Arm® Cortex-v8M architecture. Compared with Arm® Cortex-M3, it is 20% higher in CoreMark, larger in L1 Cache support and integrated with FPU and DPS
-Dual FlexCAN interfaces, one is to support the display of VCU or Dashboard battery level and the other, namely CAN bus is used to communicate with charger to control its output
-High-speed and stable SPI interface is used to stabilize communication with analog sampling front end
-192K large capacity RAM able to support fault diagnosis and protection
