ETM32F072RBT7
Product Overview
Based on Arm® Cortex®-M0+ core with embedded 12-bit DAC and programmable comparator, the ETM32F072RBT7 automotive-grade MCUs can provide cost-effective USB solution without external crystal and support USB and CAN working simultaneously, which is conducive to expanding application scenarios in industrial control and automotive electronics. With up to 24 capacitive sensing channels, users do not need to add a dedicated touch chip, it can work with proximity, touch keys, linear or rotary sensors to provide capacitive touch sensing. Hardware supports HDMI CEC, which can meet the advanced control requirements of audio and video intelligent terminal devices and is applicable to a variety of car terminals, helping customers to expand more automotive scenarios. Certified AEC-Q100, it has been widely used in blind spot detection, alarm, car OBC charger, car central control, car recorder and car audio and video system.
