Automotive PSoC™ 4: 32-bit Arm® Cortex®-M0 MCU

Overview

Automotive PSoC™ 4: Your problem solver on chip

Automotive PSoC™ 4 is a scalable and reconfigurable platform architecture for a family of programmable embedded system controllers with an ARM® Cortex®-M0+ CPU while being AEC-Q100 compliant. It combines programmable and reconfigurable analog and digital blocks with flexible automatic routing. It is a combination of a microcontroller with standard communication and timing peripherals, a capacitive touch-sensing system (CapSense) with best-in-class performance, programmable general-purpose continuous-time, and switched-capacitor analog blocks, and programmable connectivity. 

Automotive PSoC™ 4 integrates Infineon best-in-class capacitive sensing technology for demanding Human Machine Interface (HMI) applications in the automotive interior as well as exterior applications like Battery Management Systems(BMS) along with an ARM Cortex-M0/M0+ CPU, flash and memory. A programmable analog front-end with ADC, operational amplifiers, low-power comparators combined with digital blocks, and various communication interfaces such as SENT, LIN, CAN, and CAN FD provide a single-chip smart sensor with high integration and small footprint. An extended development ecosystem has been built around Automotive PSoC™ including multiple software compatibility and the famous PSoC™ Creator software, easy-to-use IDE that introduces a game-changing schematic entry design methodology.
