C8051F991-GM 8051 Capacitive Touch 8-bit Microcontroller, 25 MHz, 8 Flash(kB)

The C8051F991-GM is an ultra-low power capacitive sensing MCU featuring a powerful 8051 core with 25 MHz performance.  This MCU provides the lowest power and highest sensitivity touch sensing solution for capacitive buttons, sliders, wheels and capacitive proximity sensing. With 13 capacitive sensing inputs and sub micro amp (<1 uA) wake on touch average current consumption, the C8051F991-GM achieves unparalleled touch sensitivity, speed and ultra-low power in a 3x3 mm, QFN20. Silicon Labs also offers demos, examples and Capacitive Sense Profiler within the Simplicity Studio to accelerate development of capacitive touch sensing solutions.
