FM3565MT20X

Specialized ICS Overview

The FM3565MT20X is a CPU configuration controller manufactured by Fairchild Semiconductor. It functions as a register and multiplexer designed for microprocessor VID (Voltage Identification) applications. The device is housed in a 20-TSSOP surface-mount package with a width of 4.40mm. This component facilitates the management of processor voltage settings through its integrated control logic.

Specialized ICS Feature Summary

• Integrated CPU configuration controller for microprocessor VID
• Functions as a register and multiplexer for voltage identification signals
• Available in a 20-TSSOP surface-mount package

Specialized ICS Applications

• Microprocessor voltage identification circuits
• CPU configuration management systems

Specialized ICS Procurement Notes

Verify the specific ordering suffix '20X' against official Fairchild documentation to confirm if it denotes a specific tape-and-reel quantity or packaging variant, as the local source lists 'Bulk'. Ensure the 20-TSSOP footprint matches the target PCB design requirements before procurement.

Specialized ICS Selection Notes

Select this component when a dedicated hardware solution for CPU VID signal routing and registration is required. The 20-TSSOP package is suitable for space-constrained surface-mount designs. Confirm compatibility with the specific microprocessor's VID protocol requirements.

Specialized ICS Part Context

The FM3565 series includes variants such as FM3565MT and FM3565MT20. These parts serve similar roles as CPU configuration controllers. The '20X' suffix typically indicates a specific packaging or reel specification within the manufacturer's product line, distinct from the base part number functionality.

Specialized ICS Replacement Considerations

Direct replacements include FM3565MT and FM3565MT20. Verify pinout compatibility and functional equivalence for VID multiplexing before substitution.
