C8051F829-GS

Overview

The C8051F829-GS is a mixed-signal ISP Flash microcontroller from the C8051F80x-83x family by Silicon Labs. It features an 8-bit CIP-51 core with up to 25 MIPS throughput at 25 MHz. The device includes 16 kB of in-system programmable Flash memory and 256 bytes of internal data RAM. Key peripherals include a 10-bit ADC, capacitive sense module, comparators, UART, SMBus, SPI, and PCA. It operates on a 1.8 V to 3.6 V supply within a -40 °C to +85 °C temperature range.

Feature Summary

• Integrated capacitive sense module supporting buttons, sliders, wheels, and proximity sensing with auto-scan capabilities.
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.
• High-speed pipelined 8051 architecture executing most instructions in one or two system clocks.
• Flexible clock sources including an internal oscillator and external options for power-saving mode switching.

Applications

• Capacitive touch interface implementations
• Low-power embedded control systems
• Mixed-signal data acquisition applications
