C8051F930-G-GQR

Overview

The C8051F930-G-GQR is an 8-bit microcontroller from the Silicon Labs C8051F9xx series, housed in a 32-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. Key peripherals include a 10-bit ADC with 23 external inputs, two comparators, and multiple digital interfaces such as SMBus, SPI, and UART. It supports a supply voltage range of 0.9 V to 3.6 V.

Feature Summary

• Ultra-low power operation with built-in DC-DC converter for single-cell mode support
• High-speed pipelined 8051 core executing instructions in 1 or 2 system clocks
• Integrated on-chip debug circuitry for non-intrusive in-system debugging
• Comprehensive analog peripherals including 10-bit SAR ADC and programmable current reference

Applications

• Battery-powered home automation systems
• Remote control and garage door openers
• Smart metering and building HVAC control
• Fire and security monitoring devices

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status. Check for End-of-Life notices as indicated by manufacturer documentation. Ensure proper ESD handling during storage and assembly. Validate package integrity against the 32-LQFP specification before integration.

Selection Notes

Select this model for applications requiring low power consumption and high performance in a compact form factor. Consider the 32-LQFP package for ease of hand-soldering compared to QFN options. Evaluate the need for 64 kB Flash versus 32 kB variants if cost is a constraint. Ensure the 0.9 V to 3.6 V supply range matches the target battery configuration.

Part Context

This component belongs to the C8051F9xx family of ultra-low power 8-bit MCUs. It shares architectural similarities with the C8051F92x series but offers increased Flash capacity. The GQR suffix denotes the specific 32-pin LQFP package variant within the broader C8051F930 product line.

Replacement Considerations

C8051F930-G-GMR: Same functional specifications but in a 32-QFN (5x5 mm) package.
