8K52 Touch Key Application

The 8K52 is an 8-bit flash microcontroller embedded with 8051 core and capacitive touch keys solutions. The operating voltage is from 2.7V to 5.5V and operating temperature is from -40℃ to 85℃. A full choice of HXT, HIRC, LXT and LIRC oscillator functions are provided including a fully integrated system oscillator which requires no external components for its implementation.

8K52 supports up to 28-channel touch keys and includes: 32K bytes flash memory, 128 bytes Data Flash, 256bytes IRAM and 1024bytes bytes XRAM, 16×10-bit PWM, 12×12-bit high resolution ADC, SIO, I2C Slave and three channel UART communication interfaces.

All 8K52 ports are interchangeable with GPIO ports. Some ports provide high current driving forces, among which COM0~COM7 with high current driving capability, can directly drive digitrons or LED indicators and support maximum of 8 COM×16 SEG hardware driving control.

The 8K52 is an industrial grade IC with excellent anti-EFT and CS capability. It is an ideal touch key solution for home appliances that require high anti- EFT capability such as microwave ovens, kitchen hoods, dish washers, and rice cookers.
