BYD Semiconductor launches "four-in-one" MCU with high integration and low power consumption, supporting touch buttons, RFID detection, etc.

     According to BYD Semiconductor's official account, following the launch of China's first integrated touch and RFID smart lock master MCU (BF5823AM48) in August 2020, BYD Semiconductor has recently integrated product advantages and multi-dimensional upgrades. High-configuration, higher-positioned "four-in-one" MCU - BF5885AM64.

     According to reports, the "four-in-one" MCU chip can integrate and realize four functions: MCU main control, RFID smart card detection, Touch-Key touch buttons and voice playback. At the same time, the voice playback function is added, which can meet the needs of network interaction and background thread processing, and is aimed at higher-end customer groups.

     In addition to high integration and high configuration, this 4-in-1 MCU chip is based on a highly integrated and low-power design, with a static power consumption of less than 30uA (touch buttons@4Hz, RFID@2Hz), which is better than the industry average at the same time lower than the previous generation.

     At the same time, it also has a high-performance core Cortex-M0 with a maximum operating frequency of 48MHz, which can work stably in an environment of -45°C~+125°C, and the I/O port electrostatic test can pass ±8KV, which has passed multiple rounds of rigorous and reliable sex test.
