32-bit Analogue MCU Addresses Vehicle BMS Deployments

13 May 2024

Infineon’s PSoC 4 HVPA-144K high-voltage precision analogue microcontroller unit (MCU) is meant for use in addressing the battery management system (BMS) implementations of modern automobiles.

It features an Arm Cortex-M0+ processing core capable of running at 48MHz. Up to 128kBytes of code flash memory, 8kBytes of SRAM, 8kBytes of data flash and 1kByte of supervisory flash are incorporated too. There are also a pair of high-resolution sigma-delta analogue-to-digital converters (ADCs), 4x digital filtering channels and 2x programmable gain amplifiers, as well as 11 different GPIOs. The built-in low drop-out (LDO) voltage regulator means that this MCU can be directly attached to a 12V supply. ISO26262 functional safety is supported. Either internal or external temperature sensing can be applied.
