C8051F8xx Capacitive Touch Sense MCUs​​​​​

The C8051F8xx family of capacitive sensing 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 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.

    The C8051F8xx capacitive touch sense microcontroller (MCU) processors include Silicon Labs' 2-Wire C2 Debug and Programming interface, which allows non-intrusive (uses no on-chip resources), full speed, in-circuit debugging using the production MCU installed in the final application. This debug logic supports inspection of memory, viewing and modification of special function registers, setting breakpoints, single stepping, and run and halt commands. All analog and digital peripherals are fully functional while debugging using C2. The two C2 interface pins can be shared with user functions, allowing in-system debugging without occupying package pins.
    Each device is specified for 1.8 – 3.6 V operation over the industrial temperature range (–45 to +85 °C). An internal LDO is used to supply the processor core voltage at 1.8 V. The Port I/O and RST pins are tolerant of input signals up to 2 V above the VDD supply.
