C8051F930-F-GM

Overview

The C8051F930-F-GM is an 8-bit microcontroller from the Silicon Labs C8051F9xx series, featuring a high-speed 25 MHz CIP-51 core with up to 25 MIPS throughput. 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 300 ksps throughput, two comparators, four 16-bit timers, and multiple serial interfaces including SMBus, 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 8051-compatible core delivering 25 MIPS at 25 MHz with pipelined instruction execution
• Integrated analog subsystem featuring a 10-bit ADC with auto-averaging accumulator and dual programmable comparators

Applications

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

Procurement Notes

Verify the specific suffix '-F-GM' against the manufacturer's official ordering guide to confirm package type and temperature grade. Ensure compatibility with the required PCB footprint for the 32-pin QFN package. Cross-reference the datasheet revision to validate pinout assignments and electrical characteristics prior to final procurement.

Selection Notes

Select this component when system requirements demand low-voltage operation starting at 0.9 V combined with moderate processing speed. The inclusion of a hardware SmaRTClock and extensive analog peripherals makes it suitable for sensor-based monitoring. Evaluate the 64 kB Flash capacity against application code size to ensure sufficient storage for firmware and non-volatile data logging.

Part Context

This part belongs to the C8051F9xx family of mixed-signal microcontrollers designed for low-power embedded applications. It shares architectural similarities with the C8051F92x variant but offers increased Flash memory capacity. The series emphasizes energy efficiency through multiple sleep modes and on-chip power management features like brownout detectors and LDO regulators.

Replacement Considerations

C8051F930-G-GMR: Same MCU core and specifications; differs only in packaging format (Tape & Reel vs. Tube).

FAQ
