Infineon Technologies CY8CLED16P01-28PVXIT

Overview

CY8CLED16P01-28PVXIT from Cypress Semiconductor is an integrated Powerline Communication (PLC) SoC combining FSK-based PLC PHY, full network protocol stack (Data Link/Network/Transport layers), and a PSoC® programmable analog/digital system-on-chip with HB LED controller functionality. It supports bidirectional half-duplex communication up to 2400 bps on AC/DC powerlines (110V/240V AC, 12V/24V AC/DC), implements 8-bit CRC error detection, and delivers 16-channel PWM dimming with PrISM™ modulation for EMI reduction. It is deployed in smart lighting control systems where reliable in-building communication over existing wiring is required.

For engineers reviewing the CY8CLED16P01-28PVXIT datasheet, CY8CLED16P01-28PVXIT pinout, CY8CLED16P01-28PVXIT application, or CY8CLED16P01-28PVXIT equivalent, key selection considerations include FSK modem frequency deviation (131.8/133.3 kHz), CENELEC EN 50065-1/FCC Part 15 compliance support, I²C interface timing (50/100/400 kHz), 16-channel LED dimming resolution (8–32 bits), and embedded CSMA collision avoidance with configurable BIU timeout.

Technical Context

The CY8CLED16P01-28PVXIT integrates a dedicated FSK physical layer modem operating at 131.8 kHz (logic '1') and 133.3 kHz (logic '0'), with optional 130.4 kHz logic '1' for wider deviation. Its receiver employs HF band-pass filtering (125–140 kHz), heterodyne mixing, IF filtering, correlation, and hysteresis-comparator-based digitization to achieve robust demodulation under burst noise.

The embedded network protocol implements ISO/OSI Layers 2–4 functions including Carrier Sense Multiple Access (CSMA) with 85–115 ms random backoff, 8-/16-/64-bit addressing (up to 256 logical, 65,536 extended, or 2⁶⁴ physical nodes), PLT packet structure (6–20 byte header + 0–31 byte payload + CRC), and acknowledged/unacknowledged/repeated transmit modes with sequence-numbered retransmission.

FAQ

What powerline voltage ranges does the CY8CLED16P01-28PVXIT support?

The CY8CLED16P01-28PVXIT supports communication over 110 V/240 V AC mains and 12 V/24 V AC/DC powerlines using Cypress-provided reference coupling circuits. These designs meet CENELEC EN 50065-1:2001 and FCC Part 15 requirements. Operation on other AC/DC voltages is possible with custom coupling circuitry validated for signal integrity and safety isolation.

Does the device require an external microcontroller to operate its PLC functionality?

No. The CY8CLED16P01-28PVXIT contains a complete embedded PLC protocol stack (Data Link, Network, and Transport layers) and an M8C 24 MHz processor that executes all PLC packet handling, CSMA arbitration, and ACK/NACK management autonomously. An external MCU is optional - used only for higher-layer application logic or HMI interfacing via I²C.

How is PrISM™ modulation different from standard PWM for LED control?

PrISM™ (Programmable Random Illumination Spectrum Modulation) spreads LED switching energy across a frequency band instead of concentrating it at a single PWM frequency. This reduces peak radiated emissions by >10 dB and eliminates perceptible 100/120 Hz flicker - critical for meeting IEC 61000-3-2 harmonic limits and visual comfort standards in commercial lighting.

Can the CY8CLED16P01-28PVXIT coexist with other PLC devices on the same powerline?

Yes. Its built-in CSMA mechanism with Band-In-Use (BIU) detection monitors the 131.5–133.5 kHz band for activity before transmission. If the band is occupied, it waits a randomized 85–115 ms interval before retrying - preventing packet collisions and enabling reliable multi-node operation on shared powerline segments.
