C8051F80x/1x/2x/3x Capacitive Touch Sense MCUs

The C8051F8xx family of capacitive sensing microcontrollers (MCUs) provides an easy and reliable solution for capacitive buttons, sliders, wheels and capacitive proximity sensing. The C8051F800 family builds upon the C8051F700 MCU family by adding a lower-pin count, small form factor option to the industry’s fastest capacitive touch sense solutions. The C8051F800 adds 16-, 20- and 24-pin package options to the existing 48- and 64-pin C8051F700, providing more options to fit products with the optimal pin count, size and cost. Additional resources such as a 10-bit ADC and digital PWM provide additional human interface support for accelerometers, vibratory haptic feedback, LED illumination control, temperature sensing and resistive touch screen sensing.

With on-chip power-on reset, VDD monitor, watchdog timer and a clock oscillator, the C8051F8xx devices are truly stand-alone, system-on-a-chip solutions. The flash memory can be reprogrammed even in-circuit, providing non-volatile data storage, and also allowing field upgrades of the 8051 firmware. User software has complete control of all peripherals, and may individually shut down any or all peripherals for power savings.
