C8051F911-D-GMR

Overview

The C8051F911-D-GMR is an 8-bit microcontroller from Silicon Labs featuring a high-speed CIP-51 core with up to 25 MIPS throughput at a 25 MHz clock. It integrates 16 kB of in-system programmable Flash memory and 768 bytes of RAM. The device includes a 10-bit SAR ADC with up to 300 ksps throughput, two voltage comparators, and a built-in DC-DC converter supporting operation down to 0.9 V. It offers 16 I/O pins, hardware SMBus, dual SPI, and UART interfaces within a 24-pin QFN package.

Feature Summary

• Ultra-low power architecture with sleep modes as low as 10 nA and rapid wake-up capabilities
• Integrated DC-DC converter enabling single-cell battery operation from 0.9 V
• High-resolution analog subsystem with 10-bit ADC, programmable gain amplifier, and temperature sensor
• On-chip debug circuitry facilitating non-intrusive in-system debugging without external emulators

Applications

• Single or dual battery powered portable devices
• Low-power industrial control systems
• Battery-operated sensor nodes
• Energy-efficient embedded controllers

Procurement Notes

Verify the specific suffix 'D-GMR' against current manufacturer documentation to confirm package type and tape-and-reel configuration. Confirm availability status as distribution listings may indicate obsolete or end-of-life status for this specific revision. Ensure compatibility with required operating voltage ranges and thermal specifications for the target application environment.

Selection Notes

Select this component when ultra-low power consumption is critical alongside moderate processing requirements. The integrated DC-DC converter makes it suitable for single-cell lithium applications where voltage regulation efficiency is paramount. Consider the 10-bit ADC resolution and available digital peripherals for cost-sensitive designs requiring mixed-signal capabilities without external components.

Part Context

This part belongs to the C8051F91x family of mixed-signal microcontrollers designed for low-voltage, low-power applications. It shares architectural similarities with the C8051F90x series but distinguishes itself through higher Flash memory capacity. The family emphasizes system integration by combining a fast 8051-compatible core with extensive analog and digital peripherals on a single chip.

Replacement Considerations

Public confirmed substitute part numbers: C8051F912-D-GMR (higher Flash), C8051F901-D-GMR (lower Flash). Verify pinout and software compatibility before substitution.
