C8051F850-C-GMR

The C8051F850-C-GMR is an 8-bit microcontroller from Silicon Labs, part of the C8051F85x/86x family. It is built around the high-speed CIP-51 core, delivering up to 25 MIPS throughput with a 25 MHz clock. The device includes 8 kB of in-system programmable Flash memory organized in 512-byte sectors, and 512 bytes of RAM (256 + 256).

This microcontroller integrates a 12-bit analog-to-digital converter with up to 15 input channels, capable of 200 ksps in 12-bit mode or 800 ksps in 10-bit mode. It also features two analog comparators with programmable hysteresis, a 24.5 MHz internal oscillator (±2% accuracy), and an 80 kHz low-frequency oscillator for the watchdog timer. Communication peripherals include UART, I²C/SMBus, and SPI. On-chip debug circuitry enables full-speed, non-intrusive debugging without an emulator.

The device operates from 2.2V to 3.6V and is specified for -40°C to +85°C. It is available in a 20-pin VFQFN exposed pad package (3x3 mm) for surface-mount assembly. The part is AEC-Q100 qualified, suitable for automotive applications. Additional features include a 16-bit CRC engine, a 32-bit unique identifier, and up to 15 general-purpose I/O pins with crossbar assignment.
