C8051F808-GUR

Overview

The C8051F808-GUR is an 8-bit mixed-signal microcontroller from the Silicon Labs C8051F80x-83x family, featuring a CIP-51 core operating at up to 25 MHz. It integrates 16 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 Capacitance to Digital Converter for sensing applications, 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 Capacitance to Digital Converter supporting buttons, sliders, wheels, and capacitive proximity sensing with auto-scan capabilities.
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.
• High-speed pipelined CIP-51 architecture executing 70% of instructions in one or two system clocks.
• Flexible clock sources allowing on-the-fly switching between internal oscillators and external crystals or RC circuits.

Applications

• Capacitive touch interface implementations
• In-system programming and debugging environments
• Low-voltage portable embedded systems

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package integrity upon receipt. Check datasheet revision status as this family is marked Not Recommended for New Designs. Ensure compatibility with existing design constraints before procurement.

Selection Notes

Select this model for designs requiring integrated capacitance sensing alongside standard 8-bit MCU functions. Verify pinout compatibility with QSOP-24 footprints. Consider power consumption profiles across different clock modes. Evaluate peripheral availability against specific application requirements.

Part Context

This component belongs to the C8051F80x-83x series of mixed-signal ISPs. It shares architectural similarities with other members like the C8051F800 and C8051F818, differing primarily in memory size and peripheral configurations. The GUR suffix indicates a tape and reel packaging option.

Replacement Considerations

Consult the manufacturer's product selection guide for direct functional equivalents within the same family. Verify pin-to-pin compatibility when substituting with other C8051F8xx variants.
