C8051F832-GSR

Overview

The C8051F832-GSR is a mixed-signal ISP Flash MCU from the Silicon Labs C8051F80x-83x family. It features a high-speed 8051 μC core with up to 25 MIPS throughput at a 25 MHz clock. 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 of 1.8 to 3.6 V within a temperature range of –40 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 debug without requiring external emulation hardware.
• Pipelined instruction architecture executes 70% of instructions in 1 or 2 system clocks for efficient processing.
• Hardware-enhanced serial ports including UART, SMBus, and SPI provide versatile digital communication options.

Applications

• Capacitive touch sensing interfaces
• In-system programming applications
• Portable battery-powered devices

Procurement Notes

Verify the specific suffix against the manufacturer's current product selection guide. Confirm package type availability as the datasheet lists multiple options. Check for 'Not Recommended for New Designs' status before finalizing procurement plans. Ensure environmental specifications match the intended operating conditions.

Selection Notes

Select this component when a fully integrated mixed-signal solution with capacitive sensing is required. Consider the 10-bit ADC resolution and sampling rate for analog signal acquisition needs. Evaluate the 16 kB Flash capacity against application code size requirements. Verify that the 1.8 V to 3.6 V supply range aligns with the system power architecture.

Part Context

This part belongs to the C8051F80x-83x series of mixed-signal microcontrollers. The family shares a common CIP-51 core and peripheral set, differing primarily in memory sizes and pin counts. The GSR suffix typically denotes a specific tape-and-reel packaging configuration for automated assembly processes.

Replacement Considerations

Consult the official product selection guide for direct pin-compatible alternatives within the C8051F8xx series. Verify memory and peripheral overlaps before substituting. Cross-reference electrical characteristics to ensure compatibility with existing circuit designs.
