C8051F911-D-GM

Overview

The C8051F911-D-GM is an 8-bit microcontroller from Silicon Labs featuring the CIP-51 core. It operates on a supply voltage of 0.9 to 3.6 V and supports a maximum clock frequency of 25 MHz, delivering up to 25 MIPS throughput. The device includes 16 kB of in-system programmable Flash memory and 768 bytes of RAM. It integrates a 10-bit SAR ADC with up to 15 external inputs, two comparators, and multiple digital peripherals including SMBus, SPI, and UART interfaces.

Feature Summary

• Ultra-low power operation with sleep modes as low as 10 nA for memory retention
• Integrated DC-DC converter enabling single-cell battery operation down to 0.9 V
• High-speed pipelined 8051 architecture executing most instructions in one or two system clocks
• On-chip debug circuitry supporting full-speed non-intrusive in-system debugging

Applications

• Single-cell battery powered devices
• Portable consumer electronics
• Low-power industrial monitoring systems
• Battery-operated sensor nodes

Procurement Notes

Verify the specific suffix 'D' indicates tape and reel packaging versus tube options when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the component meets the required operating temperature range of -40°C to +85°C for the intended application environment.

Selection Notes

Select this model for applications requiring ultra-low standby current and single-cell battery support. The integrated DC-DC converter simplifies power management design. Consider the 10-bit ADC resolution and available I/O count against system requirements. Verify that the 25 MHz performance meets processing needs while maintaining low power targets.

Part Context
