C8051F862-C-GSR

Overview

The C8051F862-C-GSR 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 input channels, two analog comparators, and multiple communication peripherals including 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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and temperature grade. Check for end-of-life notices as this family may be marked not recommended for new designs. Ensure compatibility with existing PCB footprints and programming interfaces before procurement.

Selection Notes

Select this model for applications requiring a cost-effective 8-bit MCU with integrated analog peripherals. The 16-pin SOIC package suits space-constrained designs needing basic connectivity. Consider the -Gx suffix for commercial temperature ranges. Evaluate if the 8 kB Flash and 512 Bytes RAM meet project requirements compared to higher-capacity variants in the same series.

Part Context

This component belongs to the C8051F85x/86x low-cost 8-bit MCU family by Silicon Laboratories. These devices are highly integrated system-on-chip solutions designed for mixed-signal applications. The family emphasizes ease of use with on-chip debug and calibration features, targeting consumer electronics and industrial control markets where cost and integration are critical factors.

Replacement Considerations

Check for EFM8BB51F8G series as potential modern alternatives. Verify pinout compatibility and software migration efforts when substituting. Ensure the replacement meets the same voltage and temperature specifications.
