C8051F930-GQ

Overview

The C8051F930-GQ is an 8-bit microcontroller from the Silicon Labs C8051F9xx series, housed in a 32-pin LQFP (7x7 mm) package. It features a high-speed 8051 core operating at up to 25 MHz with 25 MIPS throughput. The device includes 64 kB of Flash memory and 4352 bytes of internal data RAM. It 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 ADC with 300 ksps throughput, two comparators, multiple serial interfaces, and four general-purpose timers.

Feature Summary

• Ultra-low power architecture supporting single-cell battery operation down to 0.9 V via integrated DC-DC converter
• High-performance pipelined 8051 core delivering 25 MIPS throughput at 25 MHz clock speed
• Integrated 10-bit SAR ADC with programmable throughput up to 300 ksps and burst mode capabilities
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators

Applications

• Single or dual battery powered consumer electronics
• Home automation and security systems
• Remote control and garage door openers
• Smart metering and building HVAC control
• Portable medical devices and health care monitoring

Procurement Notes

Verify the specific ordering suffix GQ corresponds to the 32-LQFP package variant. Confirm the part status as End-of-Life or Last Time Buy if sourcing through distributors. Ensure compatibility with existing PCB footprints for the 7x7 mm LQFP form factor. Check for RoHS compliance documentation matching the manufacturing date code.

Selection Notes

Select this component when low-voltage operation below 1.8 V is required using a single cell. Choose over the F92x variant if 64 kB of Flash memory is necessary instead of 32 kB. Consider the LQFP package for easier manual assembly compared to QFN options. Verify that the 25 MHz maximum frequency meets the processing requirements for the target application.

Part Context

This MCU belongs to the C8051F9xx family, designed for ultra-low power applications. It shares architectural similarities with other C8051F series devices but distinguishes itself with the ability to operate at voltages as low as 0.9 V. The F930 variant specifically offers double the Flash capacity of the F920 counterpart within the same pinout configuration.

Replacement Considerations

C8051F930-GM: Same electrical specifications but packaged in a 32-QFN (5x5 mm) format.
