C8051F912-D-GU

Overview

The C8051F912-D-GU is an 8-bit microcontroller from Silicon Labs featuring a high-speed CIP-51 core operating at up to 25 MHz. It integrates 16 kB of in-system programmable Flash memory and 768 bytes of RAM. The device includes a 12-bit SAR ADC with a throughput of 75 ksps, two voltage comparators, and a built-in DC-DC converter supporting operation down to 0.9 V. Communication interfaces include SMBus, dual SPI, and UART. It is housed in a 24-pin QFN package.

Feature Summary

Ultra-low power architecture with sleep modes as low as 300 nA and rapid wake-up capabilities
Integrated DC-DC converter enabling single-cell battery operation from 0.9 V to 3.6 V
High-resolution 12-bit analog-to-digital converter with auto-averaging accumulator
On-chip debug circuitry facilitating non-intrusive in-system programming and debugging

Applications

Single or dual battery powered sensor nodes
Wireless magnetoresistive sensor networks for UXO detection
Low-power industrial monitoring systems
Portable medical devices requiring precise analog measurement

Procurement Notes

Verify the specific suffix 'D-GU' against the manufacturer's current ordering guide to confirm package type and temperature range. Confirm RoHS compliance status via the latest datasheet revision. Check for obsolescence notices or PCNs regarding supply chain changes before finalizing procurement plans.

Selection Notes

Select this component when system requirements demand ultra-low standby current combined with a 12-bit ADC and integrated power management. Ensure the application utilizes the 0.9 V to 3.6 V input range compatible with the internal DC-DC converter. Verify that the 16 kB Flash capacity meets code storage needs alongside the 768-byte RAM constraint.

Part Context

This part belongs to the C8051F91x series within the Silicon Labs C8051F family. These are mixed-signal System-on-Chip microcontrollers designed for high performance and low power consumption. The series shares architectural similarities with the C8051F90x but offers increased Flash memory capacity.
