C8051F317-GMR

Overview

The C8051F317-GMR is an 8-bit microcontroller from the Silicon Labs C8051F31x family, featuring a CIP-51 core with up to 25 MIPS throughput at a 25 MHz clock. It integrates 16 kB of ISP Flash memory and 1280 bytes of internal data RAM. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports a temperature range of –40 °C to +85 °C. It is housed in a 24-pin QFN package and provides 21 I/O pins.

Feature Summary

• Features a high-speed pipelined CIP-51 architecture that executes most instructions in one or two system clocks for improved throughput compared to standard 8051 cores.
• Includes on-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without requiring external emulation hardware.
• Offers flexible digital peripheral configuration through a programmable digital crossbar, allowing serial ports and I/O pins to be mapped to various physical locations.

Applications

• Industrial control systems
• Consumer electronics devices
• Sensor processing applications

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the package type matches the required PCB footprint. Ensure the operating voltage and temperature ranges align with the target application environment before finalizing procurement decisions.

Selection Notes

Select this component when a fully integrated mixed-signal MCU with high-speed processing is required. It is suitable for designs needing significant onboard memory and flexible I/O mapping. Consider alternative parts if specific analog peripherals like ADCs are not needed, as this variant lacks them.

Part Context

This part belongs to the C8051F31x series of 8/16 kB ISP Flash MCUs. The family shares a common core and peripheral set, differentiated primarily by memory size and the presence of analog components like ADCs. The C8051F317 specifically omits the ADC found in other variants.

Replacement Considerations

Check for direct pin-compatible replacements within the same C8051F31x family. Verify software compatibility if migrating between variants with different memory sizes or peripheral configurations.
