CY8CPLC20-48LFXI

Overview

The CY8CPLC20-48LFXI is a Power Line Communications (PLC) integrated circuit from Infineon Technologies, designed for data transmission over existing electrical wiring. It operates within the 2 MHz to 30 MHz frequency range and supports a data rate of up to 2.4 kb/s. The device utilizes Frequency Shift Keying (FSK) modulation techniques to ensure reliable communication. It is housed in a 48-VFQFN package with an exposed pad, measuring 7x7 mm, suitable for surface-mount applications.

Feature Summary

• Integrates PLC modem functionality for direct connection to power lines
• Supports FSK modulation for robust signal transmission
• Operates at low data rates optimized for control and monitoring tasks

Applications

• Home automation systems requiring power line signaling
• Industrial control networks utilizing existing electrical infrastructure
• Smart metering and utility grid communication interfaces

Procurement Notes

Verify the specific suffix variant against official Infineon documentation to confirm pinout compatibility and thermal requirements. Ensure that the 48-VFQFN package handling procedures meet your manufacturing standards for exposed pad soldering. Cross-reference the latest datasheet revision to confirm regulatory compliance status and recommended operating conditions before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require communication over AC power lines without additional cabling. It is appropriate for applications needing simple, low-speed data links where cost-effective implementation over existing wiring is prioritized. Consider the 2.4 kb/s data rate limit and 2-30 MHz operational bandwidth when evaluating system throughput requirements against alternative high-speed PLC solutions.

Part Context
