High Noise Immunity Enhanced Touch A/D MCU

The new BS84C12CA incorporates all the excellent noise immunity features of the previous BS84C12C series and additionally has full pin compatibility with the BS84C12x. This new device however, provides a higher range of system resources and is also suitable for use as a master MCU. These features combine to ensure the device is suitable for use in applications which require touch keys, LED display and temperature measurement. Applicable products could be electric teapots, air fryers and smoke exhaust ventilators, etc.

This new device provides 12 touch keys all of which have passed the conductive susceptibility dynamic 10V test. The device has an operating voltage of 1.8V~5.5V, a 4K×16 Flash Program Memory, a 512×8 Data Memory, a 512×8 EEPROM, an IAP function, a 12-bit A/D converter with a high accuracy reference voltage up to±1%, a high speed UART interface and SPI/I²C interfaces. Holtek also fully supports the device with a comprehensive suite of hardware and software development tools as well as a touch key function library which enables designers to develop their products more rapidly.
