C8051F930-G-GQ

Overview

The C8051F930-G-GQ is an 8-bit microcontroller from the Silicon Labs C8051F9xx series, housed in a 32-pin LQFP package. It features a high-speed pipelined 8051 core operating at up to 25 MHz with 25 MIPS throughput. The device includes 64 kB of in-system programmable Flash memory and 4352 bytes of internal data RAM. Key analog peripherals consist of a 10-bit SAR ADC with up to 23 external inputs, two comparators, and a built-in temperature sensor. Power management is supported by a built-in DC-DC converter and LDO regulator, enabling operation across a supply voltage range of 0.9 V to 3.6 V.

Feature Summary

• Integrated on-chip debug circuitry for full-speed, non-intrusive in-system debugging without requiring external emulators.
• Hardware SmaRTClock oscillator capable of operating down to 0.9 V with minimal supply current consumption.
• Flexible I/O architecture featuring 24 port pins that are 5 V tolerant with programmable drive strength.
• Concurrent availability of hardware SMBus, dual SPI, and UART serial ports for simultaneous communication.

Applications

• Single or dual battery powered embedded systems
• Low power industrial monitoring applications
• Portable instrumentation devices

Procurement Notes

Verify the specific suffix GQ corresponds to the 32-LQFP (7x7 mm) package configuration required for your PCB layout. Confirm the revision level matches your design specifications, as this component is marked Not Recommended for New Designs. Ensure compatibility with existing toolchains and development kits before finalizing procurement decisions.

Selection Notes

Select this component when a robust 8051 architecture with mixed-signal capabilities is required within a compact LQFP footprint. Consider the integrated DC-DC converter for efficient power management in single-cell battery applications. Evaluate the 10-bit ADC resolution and comparator features against your signal conditioning requirements to ensure adequate performance for your sensing interface needs.

Part Context

This part belongs to the C8051F9xx family of low-power mixed-signal microcontrollers. It shares architectural similarities with other members like the C8051F92x but offers increased Flash capacity. The series is characterized by its high-speed CIP-51 core and extensive analog peripheral integration, targeting cost-sensitive applications requiring significant processing power and connectivity.
