C8051F807-GUR

Overview

The C8051F807-GUR is an 8-bit mixed-signal ISP Flash MCU from the C8051F80x-83x family. It features a high-speed 8051 core with up to 25 MIPS throughput at a 25 MHz clock. The device includes 16 kB of in-system programmable Flash memory and 512 bytes of internal data RAM. Key peripherals include a 10-bit ADC supporting up to 500 ksps, a Capacitance to Digital Converter for sensing applications, and hardware-enhanced serial interfaces including UART, SMBus, and SPI.

Feature Summary

• Integrated Capacitance to Digital Converter supports buttons, sliders, wheels, and capacitive proximity sensing with fast conversion times and auto-scan capabilities.
• On-chip debug circuitry facilitates full-speed, non-intrusive in-system debugging without requiring external emulation hardware.
• Hardware-enhanced digital peripherals provide dedicated UART, SMBus, and SPI serial ports alongside general-purpose timers and a Programmable Counter Array.
• Built-in voltage supply monitor and multiple reset sources ensure reliable operation across the specified temperature range.

Applications

• Capacitive touch sensing interfaces for buttons, sliders, and proximity detection
• Mixed-signal control systems requiring analog-to-digital conversion and comparator functions
• Embedded applications utilizing in-system programming and on-chip debugging
• Battery-powered devices leveraging low-voltage operation and power management modes

Procurement Notes

Verify component authenticity through authorized Silicon Labs distributors or certified partners. Confirm that the specific ordering suffix matches the required package type and temperature rating. Check current lifecycle status as this family may be designated Not Recommended for New Designs. Ensure compatibility with existing development tools and software libraries before procurement.

Selection Notes

Select this model when 16 kB of Flash and 512 bytes of RAM are sufficient for the application logic. Choose this variant over others in the F80x series if the specific pinout and peripheral combination of the C8051F807 aligns with the design requirements. Consider the integrated Capacitance to Digital Converter if touch sensing is needed without external components. Evaluate the 24-Pin QSOP package availability against board space constraints.
