C8051F865-C-GS

Overview

The C8051F865-C-GS is an 8-bit microcontroller from the Silicon Labs C8051F85x/86x family, featuring a high-speed CIP-51 core with up to 25 MIPS throughput at a 25 MHz clock. It integrates 8 kB of in-system programmable Flash memory and 512 Bytes of RAM. The device includes a 12-bit ADC with up to 16 channels, two analog comparators, and communication peripherals such as UART, I2C/SMBus, and SPI. Operating within a supply voltage range of 2.2 V to 3.6 V, it supports commercial temperature grades (-40°C to +85°C) and is housed in a 16-pin SOIC package.

Feature Summary

• High-performance pipelined CIP-51 core compatible with standard 8051 instruction sets
• Integrated mixed-signal capabilities including 12-bit ADC and analog comparators
