APM32F072x8xB series MCU is based on Arm® Cortex®-M0+ core, built-in 12 bit DAC and programmable analog comparator, can provide a cost-effective USB solution without external crystal oscillator, and support the use of USB. It has up to 24 capacitive sensing channels, and users can utilize proximity, touch key, linear or rotary sensors without adding an external touch IC. Supports HDMI CEC function, which can meet the advanced control requirements of audio and video equipment. At present, it can be widely used in computer and game peripherals, e-cigarettes, VR glasses, BMS, capacitive touch appliances and industrial handheld terminals.
