MPL460AT-I/4LB

Telecom Overview

The MPL460AT-I/4LB is a network controller and processor IC from Microchip Technology, designed for power line communication (PLC) applications. It integrates a two-die architecture comprising the PL360B PLC modem and its associated driver circuitry. This component facilitates data transmission over electrical wiring infrastructure. The device operates within an industrial temperature range of -40°C to +85°C and is housed in a QFN package. It serves as a core processing unit for smart metering and home automation systems requiring robust PLC connectivity.

Telecom Feature Summary

• Integrates a dual-die architecture combining the PL360B modem with a dedicated driver stage
• Provides complete physical layer and MAC functionality for power line communication networks
• Supports industrial-grade operation across extended temperature ranges for utility applications

Telecom Applications

• Smart grid metering infrastructure
• Home area network (HAN) gateways
• Power line communication modems

Telecom Part Context

This part belongs to the MPL460 family of PLC controllers. It is functionally related to the MPL460A-I/4LB but includes specific suffixes indicating tape-and-reel packaging. The 'I' designation confirms industrial temperature rating, while '4LB' identifies the specific QFN package variant used for surface mount assembly.

Telecom Replacement Considerations

The MPL460A-I/4LB is a closely related variant within the same product family. Verification of the packaging suffix is required when substituting, as the 'T' in MPL460AT indicates reel packaging compared to tray options. Ensure pinout compatibility and firmware support are confirmed before replacement.
