C8051F862-C-IS

Overview

The C8051F862-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 input 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 supports industrial temperature ranges (-40°C to +125°C) and offers on-chip debug capabilities.

Feature Summary

• High-performance pipelined CIP-51 core compatible with standard 8051 instruction sets
• Integrated 12-bit ADC supporting up to 16 channels with internal or external voltage references
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators
• Flexible I/O architecture with crossbar-enabled pins and 5 V-tolerant inputs

Applications

• Industrial control systems requiring robust analog signal processing
• Data acquisition modules utilizing high-resolution ADCs
• Embedded devices needing reliable serial communication interfaces
• Battery-powered applications benefiting from low-power operational modes

Procurement Notes

Verify the specific suffix '-IS' confirms the industrial temperature range (-40°C to +125°C) and SOIC-16 package against the manufacturer's current ordering guide. Confirm RoHS compliance status for the specific revision. Check for any recent product change notices (PCN) regarding assembly or material changes that may affect long-term availability or specifications.

Selection Notes

Select this component when a cost-effective 8-bit MCU with integrated analog peripherals is required. Ensure the 8 kB Flash capacity meets application firmware needs. Verify that the 16-pin SOIC package fits the PCB layout constraints. Consider the -Gx variant if only commercial temperature range is sufficient, as it may offer different pricing or availability dynamics compared to the industrial grade.

Part Context

This part belongs to the C8051F85x/86x series, designed as a low-cost system-on-chip solution. It replaces older discrete logic designs by integrating mixed-signal capabilities directly onto the silicon. The family emphasizes ease of development through extensive on-chip debugging features and compatibility with standard 8051 toolchains, facilitating migration for legacy projects.

Replacement Considerations

Public confirmed substitute: EFM8BB51F8I-C-QFN20R. Note that this alternative differs in package type (QFN vs SOIC) and core architecture (EFM8 vs CIP-51), requiring schematic and firmware adaptation.
