APM32 Microcontrollers
APM32A103
Product Overview
The APM32A103 automotive-grade MCUs based on Arm® Cortex®-M3 core with integrated 256KB Flash, 128KB SRAM, and abundant storage to meet the demand of large-capacity cache for automotive applications. It provides "dual CAN" communication interface and complies with 2.0A and 2.0 specification, communication rates up to 1Mbit/s. It supports independent USB and CAN, which is suitable for a wide range of car terminals and helps customers to expand more automotive scenarios. Certified AEC-Q100, it has been successfully applied in automotive fields such as Car Reversing Aid System,Window Lifter,BMS,Automobile Electric Tailgate System,BMS,Car Navigation,Automobile Instrument，T-BOX and Interior Atmosphere Lamp.
