C8051F930-G-GM

Overview

The C8051F930-G-GM is an 8-bit microcontroller from the Silicon Labs C8051F9xx series, featuring a high-speed CIP-51 core operating at up to 25 MHz. It integrates 64 kB of in-system programmable Flash memory and 4352 bytes of internal data RAM. The device supports a supply voltage range of 0.9 V to 3.6 V, utilizing a built-in DC-DC converter for one-cell mode operation. Key peripherals include a 10-bit SAR ADC with 23 external inputs, two comparators, four general-purpose 16-bit timers, and multiple serial interfaces including SMBus, dual SPI, and UART.

Feature Summary

• Ultra-low power architecture with integrated DC-DC converter enabling single-cell battery operation down to 0.9 V.
• High-performance CIP-51 core delivering up to 25 MIPS throughput with pipelined instruction execution.
• Comprehensive analog subsystem featuring a 10-bit ADC with auto-averaging accumulator and on-chip temperature sensor.
• Flexible digital I/O with 5 V tolerance and hardware crossbar allowing dynamic pin assignment.

Applications

• Single or dual battery powered devices
• Home automation systems
• Remote control units
• Smart metering applications

Procurement Notes

Verify that the specific suffix 'GM' corresponds to the 32-pin QFN package as documented in the official datasheet. Confirm the component status is active, noting that the C8051F9xx family is marked as not recommended for new designs. Ensure compatibility with existing firmware architectures before procurement.

Selection Notes

Select this model when 64 kB of program memory is required alongside extensive analog capabilities. The integrated DC-DC converter makes it suitable for low-voltage single-cell applications where efficiency is critical. Consider alternative packages if hand-solderability is a priority, as the QFN variant requires specific assembly techniques.

Part Context

This component belongs to the C8051F9xx family of ultra-low power 8051 microcontrollers. It shares architectural similarities with the C8051F92x but offers double the Flash capacity. The device is part of Silicon Labs' legacy 8-bit portfolio, designed for cost-sensitive embedded applications requiring robust analog performance.

Replacement Considerations
