C8051F972-A-GM

C8051F97x Low-Power Capacitive Sense MCUs

The C8051F972-A-GM is an ultra-low power capacitive sensing microcontroller (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 sub micro amp (<1 uA) wake on touch average current consumption, the C8051F972-A-GM achieves unparalleled touch sensitivity, speed and ultra-low power in a 4x4 mm, QFN24. We also offer demos, examples and Capacitive Sense Profiler within Simplicity Studio to accelerate development of capacitive touch sensing solutions.
