Holtek is delighted to announce the release of its new Touch A/D Flash MCU, the BS86E20CA. This new device continues to incorporate excellent noise immunity features and additionally has full pin compatibility with the BS86E16C. Compared with the BS86D20x and BS86E16C predecessor devices, this new device provides a higher range of system resources. These features combine to ensure the device is suitable for use in applications which require multiple touch key and other complex functions, such as wall mounted boilers, air fryers, kitchen scales, temperature controllers and fitness equipment, etc.
This new device provides 20 touch keys which have an automatic detection function. All of the touch keys have passed the conductive susceptibility dynamic 10V test. The device has an operating voltage of 1.8V~5.5V and with regards to memory has 16K×16 of Flash Program Memory, 1024×8 of Data Memory and a 1024×8 EEPROM. Other functions include a software LCD driver, 12-bit A/D converter with a high accuracy reference voltage up to±1%, over current protection (OCP) function, LXT oscillator, high speed UART interface and additional SPI/I²C interfaces.
The device is suitable for use as a master MCU, which when used together with a suitable power board can implement product applications. 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 will assist designers with their rapid product development. The device is supplied in 28-pin SOP/SSOP, 44-pin LQFP and 48-pin LQFP package types.
