C8051F930-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 delivering up to 25 MIPS at a 25 MHz clock frequency. The device includes 64 kB of Flash memory and 4352 bytes of internal data RAM. Operating voltage ranges from 0.9 V to 3.6 V, supported by a built-in DC-DC converter for single-cell applications. Key peripherals include a 10-bit ADC with 23 inputs, two comparators, hardware SMBus, dual SPI, UART, four general-purpose timers, and a PCA with watchdog timer.

Feature Summary

• Integrated on-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.
• Ultra-low power architecture featuring multiple sleep modes and a hardware SmaRTClock that operates down to 0.9 V.
• High-performance 8051 core with pipelined instruction execution achieving 25 MIPS throughput.
• Comprehensive analog subsystem including a 10-bit SAR ADC with auto-averaging and programmable current reference.

Applications

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

Procurement Notes

Verify the specific suffix GQR corresponds to the 32-LQFP package variant. Confirm the revision level matches project requirements as datasheets undergo updates. Check for End-of-Life notices or Product Change Notifications regarding assembly sites or packaging labels before finalizing procurement plans.

Selection Notes

Select this component when a low-voltage 8-bit MCU with integrated analog peripherals is required. The built-in DC-DC converter makes it suitable for single-cell battery operation. Ensure the 32-LQFP footprint fits the PCB layout constraints compared to the QFN alternatives.

Part Context

This part belongs to the C8051F9xx family of ultra-low power mixed-signal microcontrollers. It shares architectural similarities with the C8051F92x but offers increased Flash capacity. The series is designed for cost-sensitive embedded applications requiring high integration and low standby currents.
