C8051F317-GM

Overview

The C8051F317-GM is an 8-bit microcontroller from Silicon Labs, part of the C8051F31x family. It features a CIP-51 core with up to 25 MIPS throughput at a 25 MHz clock frequency. The device includes 16 kB of in-system programmable Flash memory and 1280 bytes of internal data RAM. It 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. The component is housed in a 24-pin QFN package.

Feature Summary

• High-speed pipelined instruction architecture executes most instructions in one or two system clocks.
• On-chip debug circuitry enables full-speed, non-intrusive in-system debugging without external emulators.
• Programmable digital I/O crossbar allows flexible peripheral pin configuration.
• Integrated hardware-enhanced serial ports including UART, SMBus, and SPI.

Applications

• In-system programming applications requiring on-chip Flash updates
• Portable instruments utilizing low-power stop modes
• Data acquisition systems leveraging internal comparators and temperature sensors
• Industrial control interfaces using hardware serial communication ports

Procurement Notes

Verify the specific suffix 'GM' corresponds to the 24-pin QFN package variant. Confirm that the design accounts for the manufacturer's recommendation regarding new designs. Ensure compatibility with the 2.7 V to 3.6 V operating voltage range during procurement planning.

Selection Notes

Select this model when 16 kB of Flash and 1280 bytes of RAM are required alongside a 24-pin footprint. Choose over variants with ADCs if analog conversion is not needed, as this model omits the 12-bit ADC found in other family members. Verify that the 25 MHz maximum clock speed meets processing requirements.

Part Context

This component belongs to the C8051F31x series of mixed-signal microcontrollers. The family shares a common CIP-51 core and peripheral set, differentiated by memory size, package type, and specific analog peripherals like ADCs. The C8051F317 specifically targets applications needing moderate Flash capacity in a compact form factor.
