AMIS49587C5871G

Overview

The AMIS49587C5871G is a power line communications network controller and processor IC from onsemi, part of the AMIS-49587 series. It integrates an ARM7TDMI core with MAC layer handling for IEC1334-compliant PLC applications. The device operates at a data rate of 2.88 kb/s using S-FSK modulation over 50/60Hz mains. Key electrical parameters include a 50 MHz frequency, serial interface, and 3.3 V operating voltage (3 V to 3.6 V range). It draws 20 mA current and functions within -40°C to +85°C. Packaged in PLCC-28 SMD/SMT, it supports programmable carrier frequencies from 9 kHz to 95 kHz.

Feature Summary

• Integrates ARM7TDMI processor core with complete physical to MAC protocol layer handling
• Supports half-duplex communication automatically synchronized to the mains
• Features programmable carrier frequencies from 9 kHz to 95 kHz in 10 Hz steps
• Complies with IEC1334-5-1, IEC1334-4-32, and EN50065 standards

Applications

• Automatic Meter Reading (AMR)
• Remote security control systems
• Street lighting control networks
• Leakage detection for water, gas, and fire alarms

Procurement Notes

Verify component authenticity through authorized onsemi distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check for moisture sensitivity packaging requirements prior to storage. Validate ordering suffixes against current product selection guides to ensure correct package and temperature grade specifications.

Selection Notes

Select this model for low-data-rate PLC applications requiring integrated processing. Ensure system design accommodates the 3.3 V supply and PLCC-28 footprint. Verify compatibility with required IEC1334 standards. Consider external filtering for 50/60Hz suppression if specified in application circuits. Confirm baud rate requirements match available selectable options.

Part Context

This component belongs to the AMIS-49587 family of power line carrier modems. It combines analog circuitry and digital functionality on a single mixed-signal IC. The series is designed for robust communication over power lines using spread-FSK modulation, enabling signal transmission over long distances in noisy environments typical of electrical grids.
