C8051F912-D-GM

Overview

The C8051F912-D-GM is an 8-bit microcontroller from Silicon Labs featuring a high-speed 8051 core operating at up to 25 MHz. It integrates 16 kB of in-system programmable Flash memory and 768 bytes of RAM within a 24-pin QFN package. The device includes a 12-bit SAR ADC with up to 75 ksps throughput, two comparators, and multiple digital peripherals including SMBus, SPI, and UART. It supports a supply voltage range of 0.9 V to 3.6 V and incorporates a built-in DC-DC converter for low-power operation.

Feature Summary

Ultra-low power architecture with sleep modes down to 300 nA and rapid wake-up capabilities
Integrated 12-bit analog-to-digital converter with auto-averaging accumulator and burst mode
Built-in DC-DC converter enabling efficient one-cell battery operation
Flexible clocking system with internal oscillators and SmaRTClock real-time clock support

Applications

Single or dual battery powered sensor nodes
Wireless magnetoresistive sensor networks
Portable medical equipment
Low-power industrial monitoring systems

Procurement Notes

Verify component authenticity through authorized distributors as the part status is listed as obsolete. Confirm package integrity and pin alignment against the 24-QFN specification before integration. Review the latest product change notices for any manufacturing site updates. Ensure design compatibility with the specified 0.9 V to 3.6 V operating range and thermal requirements.

Selection Notes

Select this component for applications requiring mixed-signal processing with strict power constraints. The integrated DC-DC converter simplifies single-cell battery designs compared to LDO-only alternatives. Consider the 12-bit ADC resolution and available GPIO count when designing sensor interfaces. Evaluate the available development tools and debug interface support for efficient firmware implementation.

Part Context

This device belongs to the C8051F91x family of highly integrated mixed-signal microcontrollers. It shares architectural similarities with the C8051F90x series but offers enhanced memory and analog features. The CIP-51 core provides improved instruction throughput over traditional 8051 implementations while maintaining software compatibility.
