C8051F810-GSR

Overview

The C8051F810-GSR is a mixed-signal ISP Flash microcontroller from the Silicon Labs C8051F80x-83x family. It features a high-speed 8051 core with up to 25 MIPS throughput at a 25 MHz clock frequency. The device includes up to 16 kB of in-system programmable Flash memory and up to 512 bytes of internal data RAM. Analog peripherals consist of a 10-bit ADC supporting up to 500 ksps, a comparator, and a capacitance-to-digital converter. Digital interfaces include an enhanced UART, SMBus, and SPI. The unit 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 supports buttons, sliders, wheels, and capacitive proximity sensing with auto-scan capabilities.
• On-chip debug circuitry facilitates full speed, non-intrusive in-system debugging without requiring external emulation hardware.
• Pipelined instruction architecture executes a majority of instructions in one or two system clocks for efficient processing.
• Built-in voltage regulator and power management modes including idle, stop, and suspend states for optimized energy consumption.

Applications

• Capacitive touch interface implementations
• Industrial control systems
• Portable battery-powered devices
