C8051F810-GS

Overview

The C8051F810-GS is an 8-bit mixed-signal microcontroller from the Silicon Labs C8051F80x-83x family, featuring a high-speed CIP-51 core operating at up to 25 MHz. It integrates 8 KB of in-system programmable Flash memory and 512 bytes of internal data RAM. The device includes a 10-bit ADC with up to 500 ksps throughput, a capacitive sense module, and multiple digital peripherals including UART, SMBus, and SPI. It operates on a supply voltage range of 1.8 V to 3.6 V within a temperature range of –40 °C to +85 °C.

Feature Summary

• Integrated capacitive sense module supporting buttons, sliders, wheels, and proximity sensing with auto-scan capabilities
• High-speed pipelined CIP-51 core executing 70% of instructions in one or two system clocks
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators
• Flexible clock sources including an internal 24.5 MHz oscillator and support for external crystal or RC configurations

Applications

• Capacitive touch interface implementations such as buttons and sliders
• Low-voltage embedded control systems requiring mixed-signal processing
• Data acquisition applications utilizing the onboard 10-bit ADC
• Industrial monitoring devices operating within extended temperature ranges

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package variant. Check for end-of-life status notifications as this family may be discontinued. Ensure compatibility with existing design tools and development kits provided by Silicon Labs.

Selection Notes

Select this model when a compact 16-pin SOIC package is required alongside moderate Flash capacity. Consider the integrated capacitive sense features if touch interfaces are needed without external controllers. Evaluate the 1.8 V to 3.6 V supply range against system power constraints. Review pinout assignments for analog and digital functions to ensure proper crossbar configuration.

Part Context

This component belongs to the C8051F80x-83x series of mixed-signal ISP Flash MCUs. The family shares a common architecture with varying memory sizes and peripheral counts. The C8051F810 variant specifically offers 8 KB Flash and 512 bytes RAM. It utilizes the CIP-51 core which provides enhanced performance over traditional 8051 architectures.

Replacement Considerations

Consult the official product selection guide for alternative part numbers within the C8051F80x-83x family that offer different memory capacities or package options. Verify pin-to-pin compatibility before substituting. Check for updated documentation regarding any changes in electrical characteristics or recommended design practices.
