C8051F920-F-GM

Overview

The C8051F920-F-GM is an 8-bit microcontroller from the Silicon Labs C8051F9xx series, featuring a high-speed pipelined CIP-51 core operating at up to 25 MHz. It provides 32 kB of in-system programmable Flash memory and 4352 bytes of internal data 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 from 0.9 V to 3.6 V. It is housed in a 32-pin QFN package.

Feature Summary

• Integrated hardware SmaRTClock for low-power real-time clocking
• Built-in dc-dc converter enabling single-cell battery operation
• On-chip debug circuitry for non-intrusive in-system programming

Applications

• Single-cell battery powered devices
• Dual-cell battery powered devices
• Low power sensor interfaces

Procurement Notes

Verify the specific suffix 'GM' corresponds to the 32-pin QFN package variant when sourcing. Confirm that the F920 designation indicates the 32 kB Flash capacity rather than the 64 kB F930 variant. Ensure the operating environment remains within the specified -40°C to +85°C temperature range.

Selection Notes

Select this component for applications requiring precise analog acquisition alongside digital control in a compact form factor. The integrated dc-dc converter simplifies power design for single-cell lithium or alkaline batteries. Verify that the 25 MIPS throughput meets the processing requirements for the target application logic.

Part Context

This part belongs to the C8051F9xx family of mixed-signal microcontrollers designed for cost-sensitive and space-constrained embedded systems. The family shares a common peripheral set including SMBus, SPI, and UART interfaces, allowing for scalable development across different memory configurations.

Replacement Considerations

C8051F930-GM offers identical peripherals but with 64 kB of Flash memory.
