C8051F860-B-GS

Overview

The C8051F860-B-GS is an 8-bit microcontroller from the Silicon Labs C8051F series, utilizing a CIP-51 core. It features 8 kB of in-system programmable flash memory and 512 bytes of RAM. The device operates at a maximum frequency of 25 MHz with a supply voltage range of 2.2 V to 3.6 V. It includes one 12-bit ADC, one PWM unit, one SPI channel, one UART channel, and one I2C channel. The component is housed in a 16-pin SOIC package and supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Integrates a high-performance CIP-51 core with pipelined instruction execution for efficient processing within the 8051 architecture.
• Provides complete on-chip system integration including analog peripherals, digital interfaces, and memory, reducing external component requirements.
• Supports in-system programming via JTAG interface for flexible firmware updates and debugging without removal from the circuit board.

Applications

• Industrial control systems requiring robust mixed-signal processing
• Medical devices needing precise analog-to-digital conversion capabilities
• Smart instrumentation and metering applications

Procurement Notes

Verify the specific suffix 'B' against official Silicon Labs documentation to confirm any distinct manufacturing or revision characteristics compared to standard variants. Ensure the 'GS' designation aligns with current RoHS compliance standards as defined by the manufacturer. Cross-reference the full part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a compact 16-pin form factor is required alongside integrated analog functionality. The CIP-51 core offers superior performance over traditional 8051 designs while maintaining code compatibility. Consider the 2.2 V to 3.6 V supply range and industrial temperature limits when evaluating suitability for low-power or harsh environment deployments.

Part Context

This part belongs to the C8051F series of fully integrated mixed-signal microcontrollers. These devices combine a high-speed 8051-compatible CPU with extensive on-chip resources such as ADCs, DACs, comparators, and communication interfaces. The series is designed to minimize board space and power consumption while providing high performance for embedded control applications.

Replacement Considerations

Consult official Silicon Labs documentation for verified pin-compatible or functionally equivalent substitutes within the C8051F family. Verify that alternative parts match the required package type, memory size, and peripheral configuration before implementation.
