APM32A091 Series

Based on the Arm® Cortex®-M0+ core, the APM32A091 highly cost-effective automotive-grade MCUs deliver low cost, low power consumption, high integration, and robust communication interfaces. Tailored to meet diverse automotive application requirements, these MCUs introduce two programmable analog comparators, one HDMI CEC, and up to 18 capacitive sensing channels, ensuring precise recognition of touch input commands.At present, it can be widely used in OBC, T-box, ignition device, window lifter, car dashboard, power liftgate and HVAC system.
