C8051F911-D-GUR

Overview

The C8051F911-D-GUR is an 8-bit microcontroller from Silicon Labs, part of the C8051F9xx series. It features a CIP-51 core with up to 25 MIPS throughput at a 25 MHz clock speed. The device includes 16 kB of in-system programmable Flash memory and 768 bytes of RAM. Key peripherals include a 10-bit SAR ADC with up to 300 ksps throughput, two comparators, and multiple digital interfaces such as SMBus, SPI, and UART. It operates on a supply voltage range of 0.9 V to 3.6 V and supports ultra-low power modes.

Feature Summary

• Ultra-low power operation with sleep mode currents as low as 10 nA with memory retention and rapid wake-up times.
• Integrated high-speed 8051-compatible core delivering up to 25 MIPS throughput with pipelined instruction architecture.
• On-chip DC-DC converter enables efficient single-cell battery operation by stepping up voltage for internal regulation.
• Comprehensive analog subsystem featuring a 10-bit ADC with programmable gain amplifier and built-in temperature sensor.

Applications

• Single or dual battery powered portable devices
• Low-power industrial control systems
• Battery-operated medical equipment
• Smart home and IoT sensor nodes

Procurement Notes

Verify the specific suffix 'D-GUR' against the manufacturer's current ordering guide to confirm package type (QFN) and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for any recent product change notices regarding obsolescence or alternate packaging options.

Selection Notes

Select this component if your design requires a balance of processing speed and extreme power efficiency in a small footprint. The integrated DC-DC converter makes it suitable for applications running off a single lithium cell. Ensure your application can utilize the 10-bit ADC resolution and that the 16 kB Flash size meets your code storage needs.

Part Context

This MCU belongs to the C8051F9xx family, which focuses on ultra-low power mixed-signal microcontrollers. The family shares the CIP-51 core architecture but varies in memory size and peripheral sets. The C8051F911 specifically offers 16 kB Flash and 10-bit ADC capabilities, distinguishing it from the 8 kB/12-bit variants like the F902.
