C8051F807-GM

Overview

The C8051F807-GM is a mixed-signal ISP Flash MCU from the C8051F80x-83x family, featuring a high-speed 8051 core with up to 25 MIPS throughput at a 25 MHz clock. It integrates 16 kB of in-system programmable Flash and 512 bytes of internal data RAM. Key peripherals include a 10-bit ADC supporting up to 500 ksps, a capacitive sense module with 16 channels, three 16-bit timers, and a Programmable Counter Array. The device operates on a supply voltage range of 1.8 V to 3.6 V and is available in a 20-pin QFN package.

Feature Summary
