C8051F832-GS

Overview

The C8051F832-GS is a mixed-signal ISP Flash microcontroller 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 512 bytes of internal data RAM. Key peripherals include a 10-bit ADC supporting up to 500 ksps, a Capacitance to Digital Converter with 16-bit resolution, and an on-chip debug circuitry for non-intrusive in-system debugging. It operates within a supply voltage range of 1.8 to 3.6 V and supports temperature ranges from –40 to +85 °C.

Feature Summary

• Integrated on-chip debug circuitry facilitates full speed, non-intrusive in-system debug without requiring external emulation hardware.
• Capacitance to Digital Converter supports buttons, sliders, wheels, and capacitive proximity sensing with fast conversion times.
• High-speed 8051 core utilizes a pipelined instruction architecture to execute a majority of instructions in one or two system clocks.
• In-system programmable Flash memory allows for sector-based reprogramming and field upgrades of firmware.

Applications

• Embedded systems requiring capacitive touch interfaces
• Battery-powered devices utilizing low-voltage operation
• Industrial control applications needing mixed-signal processing

Procurement Notes

Verify the specific package variant (SOIC-16) matches the design requirements. Confirm that the component status is acceptable for the intended production lifecycle, as the datasheet indicates this family is not recommended for new designs. Ensure compatibility with existing development tools for the CIP-51 core.

Selection Notes

Select this model when a cost-effective mixed-signal MCU with integrated capacitive sensing is required. It is suitable for designs already utilizing the C8051F80x-83x family architecture. Consider the limited pin count and memory size against application needs before finalizing the selection.

Part Context

This component belongs to the C8051F80x-83x series of fully integrated mixed-signal system-on-a-chip solutions. The series is characterized by its direct digital interface capabilities and extensive analog peripherals integrated alongside the standard 8051-compatible processor core.

Replacement Considerations

Consult the official product selection guide for cross-referencing within the C8051F80x-83x family. Verify pinout and peripheral availability for any potential substitutes.
