C8051F996-GM

Overview

The C8051F996-GM is an 8-bit microcontroller from the Silicon Labs C8051F series, utilizing a CIP-51 core compatible with the MCS-51 instruction set. It features 32 kB of in-system programmable Flash memory and 2,048 bytes of RAM. The device operates at clock frequencies up to 25 MHz and supports a supply voltage range of 1.8 V to 3.6 V. Integrated peripherals include a 12-bit ADC with 16 channels, two 16-bit PWM units, one SPI interface, and one UART. It is housed in a 24-pin QFN package.

Feature Summary

• Integrates a high-speed CIP-51 processor core with full compatibility for standard 8051 software development environments.
• Includes on-chip analog peripherals such as a multi-channel 12-bit analog-to-digital converter and precision voltage references.
• Supports non-invasive full-speed online debugging and in-system programming via the proprietary C2 serial interface.

Applications

• Wireless sensor nodes requiring low power consumption and integrated control logic
• Industrial monitoring systems involving physical quantity measurement and analysis
• Portable battery-powered devices necessitating efficient mixed-signal processing

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature rating. Confirm current production status as some variants may be discontinued. Ensure the selected component matches the required pinout and peripheral configuration for the target design.

Selection Notes

Select this model when a balance of moderate program memory and rich analog interfaces is required. It is suitable for applications needing multiple ADC channels and PWM outputs without external components. Consider alternative C8051F models if higher clock speeds or different I/O counts are necessary.

Part Context

This component belongs to the C8051F family of mixed-signal system-on-chip microcontrollers originally developed by Cygnal and now manufactured by Silicon Labs. The series represents a transition from traditional MCUs to highly integrated SoC solutions, combining digital processing capabilities with extensive analog functionality on a single die.

Replacement Considerations

Consult official substitution lists for direct replacements. Verify that any alternative part maintains identical pin assignments and peripheral specifications to ensure hardware compatibility.
