C8051F815-GSR

Overview

The C8051F815-GSR is an 8-bit mixed-signal microcontroller from the Silicon Labs C8051F80x-83x family, featuring a high-speed pipelined 8051 core operating at up to 25 MHz. It integrates 8 KB of in-system programmable Flash memory and 512 bytes of internal RAM. The device includes a 10-bit ADC with up to 500 ksps throughput, a capacitance-to-digital converter for capacitive sensing, and multiple digital peripherals including UART, SMBus, and SPI. Powered by a 1.8 V to 3.6 V supply, it operates within a temperature range of –40 °C to +85 °C and is housed in a 16-pin SOIC package.

Feature Summary

• Integrated capacitance-to-digital converter 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
• Pipelined instruction architecture executing 70% of instructions in one or two system clocks for high throughput
• In-system programmable Flash memory allowing field upgrades and non-volatile data storage

Applications

• Capacitive touch interface implementations such as buttons and sliders
• Low-power embedded control systems requiring mixed-signal processing
• Industrial monitoring applications utilizing on-chip temperature sensors and comparators

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required reel packaging variant. Check current lifecycle status as this series may be designated Not Recommended for New Designs. Ensure compatibility with existing design tools and development kits before procurement.

Selection Notes

Select this model when a compact 16-pin solution is required for mixed-signal applications. It is suitable for designs needing integrated capacitive sensing alongside standard analog conversion. Consider the limited I/O count and memory size against application requirements. Evaluate power consumption profiles across different voltage and clock settings.

Part Context

This component belongs to the C8051F80x-83x mixed-signal ISP Flash MCU family. It shares architectural similarities with other members like the C8051F811 and C8051F817, differing primarily in memory configuration and peripheral availability. The family utilizes the CIP-51 core and supports common Silicon Labs development environments.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives within the same family. Verify that any replacement maintains identical package dimensions and electrical characteristics. Cross-reference peripheral configurations to ensure functional parity.
