The C8051F97x MCU family combines Silicon Labs proven low-power technology for the longest battery life of any MCU in its class with the industry’s highest performance and lowest power capacitive sensing solution to address the rapidly-growing human interface application market. The C8051F97x expands the capabilities of the popular C8051F99x low-power capacitive sense family with up to 43 capacitive sensing inputs, 32 kB Flash, 8 kB RAM, 7 DMA channels and a 16 x 16 MAC in packages as small as 4 mm x 4 mm.

Both families offer the industry’s leading capacitive sensing with sub micro-amp (<1 µA) wake-on-touch average current and unmatched 100:1 dynamic range to support buttons, sliders, touch pads, and capacitive proximity sensing. Simplicity Studio, a comprehensive development environment, is offered to help the quickly develop applications. Demos, examples and the Capacitive Sense Profiler are offered with Simplicity Studio to make the development of capacitive touch sensing solutions simple.
