C8051F863-C-IS

Overview

The C8051F863-C-IS 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. The device includes a 12-bit ADC with up to 16 input channels operating at 200 ksps, two analog comparators, and multiple communication peripherals including UART, I2C/SMBus, and SPI. It operates on a supply voltage of 2.2 V to 3.6 V within an industrial temperature range of –40 °C to +125 °C.

Feature Summary

• High-performance CIP-51 core with pipelined architecture for efficient instruction execution
• Integrated 12-bit ADC supporting up to 16 channels with configurable sampling rates
• On-chip debug circuitry enabling full-speed non-intrusive system debugging without external emulators
• Flexible I/O configuration via digital crossbar with 5 V-tolerant pins

Applications

• Low-cost motor control applications
• Industrial sensor interfaces
• Portable instrumentation systems

Procurement Notes

Verify the specific suffix 'IS' confirms the industrial temperature grade (-40°C to +125°C) and SOIC-16 package type as required by your design constraints. Confirm that the component status aligns with long-term availability plans, as this series may be subject to lifecycle changes. Ensure compatibility with existing programming tools and debug adapters before finalizing procurement orders.

Selection Notes

Select this model when a balance of moderate Flash capacity and rich analog peripherals is required in a compact 16-pin package. The C8051F863 variant is suitable for designs needing multiple ADC channels and standard serial interfaces. Consider the -Gx commercial grade if operation above 85°C is not required, or explore newer families for new designs due to current lifecycle recommendations.

Part Context

This component belongs to the C8051F85x/86x low-cost 8-bit MCU family designed for cost-sensitive control applications. The family shares a common architecture featuring the CIP-51 core and integrated analog peripherals. The C8051F863 specifically offers 8 kB of Flash and 512 Bytes of RAM, distinguishing it from lower-capacity variants within the same series.
