C8051F975-A-GM

The C8051F975-A-GM is an ultra-low power capacitive sensing 8-bit Microcontroller featuring a powerful 8051 core with 25MHz performance. This MCU provides the lowest power and highest sensitivity touch sensing solution for capacitive buttons, sliders, wheels and capacitive proximity sensing. With capacitive sensing inputs and sub micro amp (<lt/>1uA) wake on touch average current consumption, the C8051F975-A-GM achieves unparalleled touch sensitivity, speed and ultra-low power. With on-chip power-on reset, VDD monitor, watchdog timer and clock oscillator, the device is 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.
