The C8051F97x MCU family combines our proven low power technology for the longest battery life of any microcontroller (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 16x16 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.
