C8051F996-GU

Overview

The C8051F996-GU is an 8-bit microcontroller from the Silicon Labs C8051F9xx series, utilizing the CIP-51 8051 core. It features 4 kB of in-system programmable Flash memory and 512 bytes of RAM. The device operates at a maximum frequency of 25 MHz with a supply voltage range of 1.8 V to 3.6 V. It integrates a 12-bit ADC with 16 channels, a 10-bit DAC, and multiple communication interfaces including SPI, I2C, and UART. The component is housed in a 24-pin QSOP package and supports an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Integrates a high-speed 12-bit analog-to-digital converter with 16 external channels for precise signal acquisition.
• Includes a 10-bit digital-to-analog converter for generating analog output signals.
• Features an on-chip temperature sensor for internal thermal monitoring.
• Supports in-system programming via standard serial interfaces.

Applications

• Wireless sensor nodes requiring low power consumption
• Industrial data acquisition systems
• Battery-powered measurement devices

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature grade. Confirm RoHS compliance status through current manufacturer declarations. Check for end-of-life notices or product change notifications prior to procurement. Ensure compatibility with existing design tools and programming adapters.

Selection Notes

Select this component when a compact 8-bit MCU with integrated high-resolution analog peripherals is required. It is suitable for applications needing direct ADC/DAC functionality without external converters. Consider the 24-pin QSOP footprint for space-constrained designs. Evaluate power requirements against the 1.8 V to 3.6 V operating range.

Part Context

This part belongs to the C8051F9xx family of mixed-signal microcontrollers. These devices are designed for cost-sensitive applications requiring significant analog integration alongside processing capabilities. The family shares common architectural features but varies in memory size and peripheral counts.

Replacement Considerations

Consult official substitution guides for compatible parts within the C8051F series. Verify pinout and register compatibility before replacing. No specific substitute part numbers are confirmed in public documentation.
