C8051F865-C-IS

Overview

The C8051F865-C-IS 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 operating at 200 ksps, two analog comparators, and multiple communication peripherals including UART, I2C/SMBus, and SPI. Powered by a 2.2 V to 3.6 V supply, it operates within -40°C to +125°C and is housed in a 16-pin SOIC package.

Feature Summary

• High-performance CIP-51 core with pipelined architecture for efficient instruction execution
• Integrated 12-bit ADC supporting up to 16 input channels with flexible reference options
• On-chip debug circuitry enabling full-speed, non-intrusive system debugging without external emulators
• Flexible I/O configuration via Crossbar logic with 5 V-tolerant pins

Applications

• Low-cost motor control applications
• Industrial process control systems
• Portable battery-powered instrumentation
• Smart sensor nodes requiring analog signal acquisition

Procurement Notes

Verify the specific suffix '-IS' confirms industrial temperature range (-40°C to +125°C) and SOIC-16 packaging. Confirm RoHS compliance status through official documentation. Check for 'Not Recommended for New Designs' status before finalizing procurement plans. Ensure ordering quantities match distributor minimums.

Selection Notes

Select this component when a cost-effective 8-bit MCU with integrated analog peripherals is required. The CIP-51 core offers compatibility with standard 8051 toolchains while providing higher performance. Consider the 16-pin SOIC package for space-constrained designs needing 5 V-tolerant I/O. Evaluate power consumption requirements against the specified idle and active modes.

Part Context

This part belongs to the C8051F85x/86x series, designed for low-cost, high-integration control applications. The family shares architectural similarities but varies in memory size and pin count. The C8051F865 variant specifically targets applications needing 8 kB Flash and robust analog capabilities within a compact footprint.

Replacement Considerations

Consult the official datasheet for qualified AEC-Q100 alternatives within the same family. Verify pinout compatibility if substituting with other C8051F variants. Check for updated design recommendations as the series may be marked Not Recommended for New Designs.
