C8051F7xx Capacitive Touch Sense MCUs

The C8051F7​xx family of high pin-count capacitive touch sense microcontroller (MCU) devices for cost-sensitive, high I/O embedded systems offer a patent-pending touch sensing feature that is robust, accurate, responsive and easy to configure. Offering up to 54 general purpose I/O pins and a 25 MIPS 8051 CPU, the C8051F7xx family of microcontrollers brings a high level of processing power and flexibility to applications such as industrial controls, security systems, residential HVAC, home appliances, keyboards, cash machines and fax/printer/scanner front panels.

With on-chip power-on reset, VDD monitor, watchdog timer and clock oscillator, the C8051F70x/71x devices are 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.
