• Integrated USB 2.0 controller with clock recovery and transceiver
• High-speed 8051 core with pipelined architecture
• Automotive qualification compliant with AEC-Q100 standards
• On-chip debug circuitry for non-intrusive in-system debugging

Applications

• Motor control systems
• Sensor interface modules
• Parking assistance units
• Fluid level monitoring devices

Procurement Notes

Verify the specific suffix 'GQ' corresponds to the 32-pin LQFP package variant. Confirm that the component meets the required AEC-Q100 automotive grade specifications for your target environment. Ensure compatibility with existing PCB footprints designed for this package type before finalizing procurement orders.

Selection Notes

Select this model when a compact 32-pin solution is required alongside USB connectivity and analog signal processing capabilities. It serves as a direct alternative to larger packages while maintaining full peripheral functionality. Consider the 32 kB Flash capacity against application code size requirements during the design phase.

Part Context

This component belongs to the C8051F38x family of Flash MCUs from Silicon Labs. The series provides a unified platform for industrial and automotive applications requiring mixed-signal processing. The C8051F383 variant specifically offers reduced memory compared to higher-end models in the same family.
