C8051F395-A-GM

Overview

The C8051F395-A-GM is a mixed-signal microcontroller from the Silicon Labs C8051F39x series, featuring a high-speed pipelined 8051 core capable of up to 50 MIPS throughput at a 50 MHz clock frequency. It integrates 16 kB of in-system programmable Flash memory and 1 kB of internal data RAM. The device includes analog peripherals such as a 10-bit ADC with up to 16 external inputs, two 10-bit current output DACs, and a precision temperature sensor accurate to ±2 °C. It operates on a supply voltage range of 1.8 V to 3.6 V and is available in a 24-pin QFN package.

Feature Summary

• High-performance 8051 core with pipelined architecture executing most instructions in one or two system clocks
• Integrated mixed-signal capabilities including a 10-bit ADC, dual 10-bit current DACs, and comparator
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators
• Low-power operation with configurable clock sources and multiple power management modes

Applications

• Industrial control systems requiring precise analog signal processing
• Battery-powered devices utilizing low-power stop and suspend modes
• Data acquisition systems leveraging the programmable throughput ADC
• Embedded applications needing in-system programming via Flash memory

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and temperature grade. Check for end-of-life status as indicated by 'Not Recommended for New Designs' markings in official documentation. Ensure compatibility with existing PCB footprints for the 24-pin QFN configuration.

Selection Notes

Select this model when a balance of analog precision and digital processing speed is required within a compact form factor. Consider the 24-pin QFN package for space-constrained designs compared to the 20-pin variant found in other series members. Evaluate the need for the integrated precision temperature sensor and dual DACs against alternative MCUs with fewer analog features but potentially lower cost.

Part Context

This component belongs to the C8051F39x/37x family of fully integrated mixed-signal microcontrollers. It shares architectural similarities with the C8051F33x series but offers enhanced analog peripherals and higher performance. The device is part of Silicon Labs' portfolio of single-chip solutions designed to reduce bill-of-materials costs by integrating common peripheral functions onto a single die.

Replacement Considerations

Consult official Silicon Labs documentation for qualified pin-to-pin replacements within the C8051F39x series. Verify functional equivalence regarding analog peripheral availability and memory sizes before substituting.
