AMIS49587C5872G

Overview

The AMIS49587C5872G is a power line carrier modem manufactured by onsemi, designed for robust low data rate communication over 50/60 Hz mains power lines. It utilizes spread-FSK (S-FSK) modulation and complies with IEC1334-5-1, IEC1334-4-32, and EN50065 standards. The device integrates an ARM 7TDMI processor core with MAC layer handling. It supports programmable carrier frequencies from 9 kHz to 95 kHz in 10 Hz increments and operates in half-duplex mode. Selectable data rates include 300, 600, 1200, and 2400 baud at 50 Hz.

Feature Summary

• Integrates ARM 7TDMI processor core with complete protocol stack handling from physical to MAC layers
• Employs spread-FSK modulation for reliable signal transmission over power lines
• Features fully configurable serial interface for product configuration and application development

Applications

• Automatic Meter Reading (AMR)
• Remote security control systems
• Street lighting control networks
• Utility leak detection and fire alarm signaling

Procurement Notes

Verify the specific suffix 'C5872G' against official onsemi documentation to confirm exact pinout, temperature range, and packaging variations. Confirm current manufacturing status as legacy models may have obsolescence notices. Ensure compatibility with required IEC1334 standards for the target deployment region.

Selection Notes

Select this component for applications requiring integrated digital-analog processing on power lines. The built-in ARM core reduces external microcontroller requirements. Verify that the half-duplex operation aligns with network topology needs. Ensure the 9 kHz to 95 kHz frequency range covers local grid noise profiles.

Part Context

This part belongs to onsemi's AMIS series of power line communication solutions. It combines mixed-signal technology to integrate analog front-end circuits with digital logic on a single IC. This integration simplifies design complexity compared to discrete modem implementations.

Replacement Considerations

Check for direct cross-reference part numbers within the AMIS family or updated revisions from onsemi. Evaluate alternative PLC modems if the ARM 7TDMI architecture is no longer suitable for new designs.
