C8051F996-C-GU

Overview

The C8051F996-C-GU is an 8-bit microcontroller from Silicon Labs, part of the C8051F9xx series. It features a CIP-51 core operating at up to 25 MHz. The device integrates 8 KB of Flash memory and 512 bytes of RAM. It includes a 10-channel 12-bit ADC, capacitive sensing capabilities, and multiple communication interfaces including SMBus, SPI, and UART/USART. The unit operates within a voltage range of 1.8V to 3.6V and supports surface mount installation in a 24-QSOP package.

Feature Summary

• Integrates capacitive sensing channels for touch interface applications
• Supports ultra-low power consumption with multiple sleep modes
• Includes on-chip temperature sensor and brownout detector

Applications

• Wireless sensor nodes requiring low power operation
• Battery-powered measurement devices
• Industrial monitoring systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for end-of-life notices as availability may be restricted. Ensure storage conditions meet specified humidity requirements to prevent damage before reflow soldering.

Selection Notes

Select this model when high integration of analog peripherals and capacitive sensing is required alongside standard 8051 compatibility. Consider the 24-QSOP package constraints for board layout. Evaluate power budget against active and sleep mode currents. Verify that the 25 MHz clock speed meets real-time processing requirements for the target application.

Part Context

This component belongs to the C8051F9xx family of mixed-signal system-on-chip microcontrollers. These devices are designed for applications demanding low power and high performance. The series combines a fast CIP-51 core with extensive on-chip resources, reducing external component count and simplifying design complexity compared to traditional discrete solutions.

Replacement Considerations

Check for compatible variants within the C8051F9xx series such as C8051F98x models. Verify pin-to-pin compatibility and peripheral overlap before substitution. Review errata documents for any functional differences between revisions.
