C8051F392-A-GM

Overview

The C8051F392-A-GM is a mixed-signal microcontroller from the C8051F39x family, featuring an 8051 core with up to 50 MIPS throughput. It includes 16 kB of Flash memory, 1 kB of internal data RAM, and operates within a 1.8 V to 3.6 V supply range. The device integrates a 10-bit ADC with programmable throughput up to 500 ksps, two 10-bit current output DACs, and an analog comparator. It supports digital interfaces including two SMBus ports, one SPI port, and one UART. The component is housed in a QFN-20 package and supports an operating temperature range of -40 °C to +105 °C.

Feature Summary

• High-speed pipelined 8051 architecture executing most instructions in one or two system clocks
• Integrated precision temperature sensor accurate to ±2 °C without user calibration
• On-chip debug circuitry enabling full-speed non-intrusive in-system debugging
• Flexible clock sources including calibrated internal oscillators for crystal-less operation

Applications

• Battery-powered applications requiring low power consumption
• Electronic toys and games
• Motor control systems
• Optical communication devices

Procurement Notes

Verify that the specific ordering suffix matches the required package and temperature grade. Confirm RoHS compliance status through official documentation. Check for 'Not Recommended for New Designs' notices on manufacturer datasheets before finalizing procurement decisions.

Selection Notes

Select this component when a small form factor QFN-20 package is required alongside mixed-signal capabilities. Ensure the application benefits from the integrated analog peripherals such as the high-speed ADC and current mode DACs. Verify that the 16 kB Flash size meets program storage requirements.

Part Context

This part belongs to the C8051F39x series, which serves as a next-generation upgrade to the C8051F33x family. It maintains footprint and code compatibility while offering increased speed, additional RAM, and extended temperature ranges. The series represents a highly integrated system-on-a-chip solution designed for standalone operation.

Replacement Considerations

The C8051F392-A-GM is marked as Not Recommended for New Designs. Evaluate alternative components from the manufacturer's current portfolio for new projects.
