C8051F316-GM

Overview

The C8051F316-GM is an 8-bit microcontroller from the Silicon Labs C8051F31x family, featuring a high-speed CIP-51 core with up to 25 MIPS throughput at a 25 MHz clock frequency. It integrates 16 kB of in-system programmable Flash memory and 1280 bytes of internal data RAM. The device includes hardware-enhanced UART, SMBus, and SPI serial ports, four general-purpose 16-bit counter/timers, and a 16-bit Programmable Counter Array (PCA). It operates on a supply voltage of 2.7 V to 3.6 V within a temperature range of –40 °C to +85 °C.

Feature Summary

• Features a fully 8051-compatible CIP-51 core with pipelined architecture for improved instruction execution speed.
• Includes on-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.
• Provides versatile digital peripherals including hardware-enhanced UART, SMBus, and SPI interfaces.
• Integrates a Programmable Counter Array (PCA) with capture/compare modules and timer capabilities.

Applications

• Embedded systems requiring in-system programming and debugging
• Industrial control applications utilizing serial communication protocols
• Sensor interface designs leveraging onboard timers and counters

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt, as the unit utilizes a surface-mount QFN-24 form factor. Ensure storage conditions align with semiconductor handling standards to prevent moisture sensitivity damage prior to soldering.

Selection Notes

Select this component for designs necessitating a robust 8051 architecture with integrated analog and digital peripherals. Consider the specific pin count and I/O requirements against the 24-pin QFN package constraints. Evaluate power consumption profiles against the specified operating voltage and temperature ranges for target environmental conditions.

Part Context

This part belongs to the C8051F31x series of mixed-signal microcontrollers. The family shares common architectural features such as the CIP-51 core and crossbar logic, differing primarily in memory sizes, package options, and peripheral availability across variants like the F310 through F317.

Replacement Considerations

Consult official documentation for qualified substitute part numbers within the same product family or next-generation equivalents. Verify pin compatibility and peripheral mapping before transitioning to alternative components.
