APM32F103 Series

The APM32F103 popular mainstream industrial-grade MCUs deliver high computing performance, efficient power consumption, and ample storage space. They come with a built-in LCD interface compatible with 8080/6800 modes. These MCUs have a broad customer application base and are certified for both IEC 61508 and IEC 60730, meeting high-reliability standards for industrial-grade applications.At present, it can be widely used in encoder, motor control, access control system, HVAC board, refrigerator compressor and ticket printer.

The APM32F103RCT7 is certified with AEC-Q100 Grade 2, meeting automotive reliability standards. It operates from -40°C to 105°C, suitable for complex conditions. Ideal for applications like HUD, head flow light, blind spot monitor, onboard central control, smart cabin, power liftgate, fault diagnostic instrument and fuel anti-theft alarm.
