C8051F860-C-GS

Overview

The C8051F860-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 Analog-to-Digital Converter with up to 16 input 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-speed pipelined CIP-51 core compatible with standard 8051 instruction sets
• Integrated 12-bit ADC with multiple input channels and configurable reference options
• On-chip debug circuitry enabling non-intrusive system debugging without external emulators
• Comprehensive peripheral set including timers, PWM, watchdog, and CRC engine

Applications

• Battery chargers
• Electronic toys and games
• Motor control systems
• Optical communications modules

Procurement Notes

Verify the specific suffix 'GS' corresponds to the commercial temperature grade (-40°C to +85°C) and 16-pin SOIC package configuration. Confirm that the component status aligns with the datasheet designation of 'Not Recommended for New Designs'. Ensure compatibility with existing design infrastructure before procurement, as alternative newer families may be recommended by the manufacturer.

Selection Notes

Select this model when a cost-effective 8-bit solution with integrated mixed-signal capabilities is required. The C8051F860 variant specifically offers the 16-pin SOIC package option suitable for space-constrained designs. Consider the internal oscillator accuracy and available GPIO count against application requirements. Evaluate the trade-off between the established C8051 architecture and potential migration to newer silicon if long-term supply assurance is critical.

Part Context

This component belongs to the C8051F85x/86x low-cost 8-bit MCU family designed for highly integrated system-on-chip applications. The series emphasizes reduced bill-of-materials by incorporating essential analog and digital peripherals directly onto the die. The C8051F860-C-GS represents a specific pinout and temperature grade variation within this broader portfolio, targeting consumer and industrial embedded control tasks.

Replacement Considerations

Public confirmed substitute part numbers are not explicitly listed in the provided documentation. Designers should consult Silicon Labs for current equivalent recommendations given the 'Not Recommended for New Designs' status.
