C8051F864-C-GS

Overview

The C8051F864-C-GS is an 8-bit microcontroller from the Silicon Labs C8051F85x/86x family, utilizing a high-speed CIP-51 core with up to 25 MIPS throughput at a 25 MHz clock. It features 8 kB of in-system programmable Flash memory and 512 Bytes of RAM (256 + 256). The device includes a 12-bit ADC with up to 16 input channels, two analog comparators, and communication peripherals including UART, I2C/SMBus, and SPI. Operating voltage ranges from 2.2 V to 3.6 V, with commercial temperature support from -40 °C to +85 °C.

Feature Summary

• High-speed CIP-51 core with pipelined architecture for efficient instruction execution
• Integrated 12-bit ADC supporting up to 200 ksps conversion rates
• On-chip debug circuitry enabling non-intrusive system debugging without external emulators
• Flexible pin mapping via crossbar-enabled general-purpose I/O

Applications

• Low-cost embedded control systems
• Data acquisition applications requiring analog signal processing
• Industrial monitoring devices
• Consumer electronics with mixed-signal requirements

Procurement Notes

Verify the specific suffix 'GS' against the manufacturer's current documentation to confirm package type and temperature grade. Confirm that the component status remains valid for your design lifecycle, as this series may be subject to obsolescence notices. Ensure compatibility with existing PCB footprints for the 16-pin SOIC package before finalizing procurement orders.

Selection Notes

Select this model when a cost-effective 8-bit solution with integrated analog peripherals is required. The CIP-51 core offers higher performance than standard 8051 architectures. Consider the 16-pin SOIC package for space-constrained designs. Evaluate power consumption requirements across different operating modes if battery operation is intended.

Part Context

This component belongs to the C8051F85x/86x family, which provides low-cost 8-bit MCU capabilities with mixed-signal integration. The family shares common architectural features such as the CIP-51 core and on-chip debug interface. Variants within the family differ primarily in memory size, package options, and temperature ratings.

Replacement Considerations

Consult official Silicon Labs documentation for verified substitute part numbers. Cross-reference pinouts and electrical specifications carefully when considering alternative components from other manufacturers.
