C8051F828-GS

Overview

The C8051F828-GS is a mixed-signal ISP Flash MCU from the C8051F80x-83x family, featuring a high-speed 8051 core with up to 25 MIPS throughput at 25 MHz. It includes up to 16 kB of in-system programmable Flash and 512 bytes of internal data RAM. Key peripherals comprise a 10-bit ADC supporting up to 500 ksps, a capacitive sense module with 16-bit resolution, comparators, and digital interfaces including UART, SMBus, and SPI. The device operates on a supply voltage of 1.8 to 3.6 V and supports packages such as 16-pin SOIC, 20-pin QFN, and 24-pin QSOP within an industrial temperature range of –40 to +85 °C.

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.
• Pipelined instruction architecture executing 70% of instructions in one or two system clocks for high processing efficiency.
• Flexible clock sources allowing on-the-fly switching between internal oscillators and external crystals or RC circuits.

Applications

• Capacitive touch interface implementations
• Industrial control systems requiring mixed-signal processing
• Portable instrumentation with low-power constraints

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches design requirements, as the family supports multiple form factors. Ensure the specific suffix corresponds to the desired variant within the C8051F80x-83x series. Review the document revision history for any updates to electrical characteristics or pin definitions prior to finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring integrated capacitive sensing alongside standard mixed-signal functions. Evaluate memory requirements against the 16 kB Flash and 512-byte RAM limits. Consider the 1.8V to 3.6V operating range for battery-powered applications. Verify that the available I/O ports and peripheral counts meet the specific interface needs of the target application design.

Part Context

This microcontroller belongs to the C8051F80x-83x family of mixed-signal ISPs Flash MCUs produced by Silicon Laboratories. The family shares a common architectural foundation based on the CIP-51 core, offering varying combinations of memory sizes and peripheral sets. These devices are designed for cost-sensitive embedded applications requiring high integration levels and flexible analog-digital co-processing capabilities.

Replacement Considerations

Consult the product selection guide in the official datasheet for direct functional equivalents within the C8051F80x-83x series. Verify pin compatibility and memory size when considering sibling models. Note that this family is marked as not recommended for new designs; evaluate newer Silicon Labs alternatives for long-term projects.
