C8051F930-F-GMR

Overview

The C8051F930-F-GMR is an 8-bit microcontroller from the Silicon Labs C8051F9xx series, featuring a high-speed CIP-51 core with up to 25 MIPS throughput at a 25 MHz clock. 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 sleep currents as low as 10 nA and rapid wake-up times
• Integrated on-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators
• Flexible clocking system with precision internal oscillators and SmaRTClock real-time clock support
• High-performance analog subsystem featuring a 10-bit ADC with auto-averaging accumulator and programmable current reference

Applications

• Single or dual battery powered devices requiring extended operational life
• Home automation and security systems
• Remote control and garage door openers
• Smart metering and building HVAC control units

Procurement Notes

Verify the specific suffix 'F' against the manufacturer's official documentation to confirm package type and temperature rating variations. Ensure the ordering information matches the required quantity format and check for any recent product change notices regarding assembly sites or material composition updates before finalizing procurement.

Selection Notes

Select this component when a balance of moderate Flash capacity and extensive analog peripheral integration is required within a compact footprint. The inclusion of a built-in DC-DC converter makes it suitable for applications operating from single-cell lithium batteries where stable voltage regulation is critical for analog performance.

Part Context

This part belongs to the C8051F9xx family of ultra-low power 8051 microcontrollers. It shares the same core architecture and peripheral set as the C8051F92x series but offers double the Flash memory capacity (64 kB versus 32 kB). The F suffix typically denotes a specific package variant or temperature grade within the broader C8051F930 product line.

Replacement Considerations

Direct substitutes within the same family include the C8051F930-G-GMR and C8051F930-TB-K, though package differences must be accounted for. Cross-family replacements like the C8051F500 offer higher speeds but differ significantly in pinout and peripheral configuration.
