APM32F051x6x8 series MCU is based on Arm® Cortex®-M0+ core and has an operating frequency of 48MHz, built-in high-speed memory flash 16-64kb, and SRAM 8KB. It is a comprehensive optimization and upgrade of product performance on the basis of APM32F030x8. The new capacitive touch function TSC can accurately identify the touch input in complex working conditions; the built-in HDMI CEC interface can meet an intelligent terminal's advanced control application requirements. It has the characteristics of high integration, good portability, broad compatibility, and vital extended control function.
