Product details
Overview
CY8CLED16P01-48LTXIT from Cypress Semiconductor is an integrated Powerline Communication (PLC) and high-brightness LED controller SoC featuring an FSK modem PHY, full OSI Layers 2–4 network protocol stack, 16-channel HB LED dimming with PrISM™ modulation, M8C 24 MHz processor, 32 KB Flash/2 KB SRAM, and I²C/DALI/DMX512 interface support - deployed in smart lighting control systems over AC/DC powerlines.
For engineers reviewing the CY8CLED16P01-48LTXIT datasheet, CY8CLED16P01-48LTXIT pinout, CY8CLED16P01-48LTXIT application, or CY8CLED16P01-48LTXIT equivalent, key selection considerations include FSK carrier frequencies (131.8/133.3 kHz), 2400 bps max baud rate, 8-bit CRC error detection, 16-channel LED PWM resolution (8–32 bits), and CENELEC EN 50065-1/FCC Part 15 compliance for 110V/240V AC coupling.
Technical Context
The CY8CLED16P01-48LTXIT implements a bidirectional half-duplex PLC physical layer using frequency-shift keying with configurable logic '0' (131.8 kHz or 130.4 kHz) and logic '1' (133.3 kHz) carriers, coupled with a receiver chain including HF band-pass filtering, mixer-based heterodyning, IF filtering, correlator-based demodulation, and hysteresis-comparator digitization.
Its embedded network protocol integrates MAC, data link, transport, and network layers - supporting CSMA with 85–115 ms random backoff, 8-/16-/64-bit addressing (up to 2⁶⁴ nodes), PLT packet structure (6–20 byte header + 0–31 byte payload + CRC), and acknowledged/unacknowledged/repeated transmit modes with automatic retransmission on timeout.
Key Specifications

|---|---|
Use Scenario: Centralized management of hundreds of LED streetlights over existing 240V AC mains wiring, enabling remote dimming, fault reporting, and energy metering. IC Role / Device Role / Timing Role: PLC transceiver + LED controller - handles both network communication (PLT packet RX/TX) and real-time PWM dimming of 16 independent lamp strings. Use Value: Eliminates dedicated control cabling; leverages PrISM™ to meet outdoor EMI requirements without added filters; supports group addressing for zone-level control. | Use Scenario: Retrofitting office ceiling fixtures with DALI-compatible dimming via 12V DC powerline, where each fixture contains multiple color-tunable LED channels. IC Role / Device Role / Timing Role: Dual-interface controller - uses I²C for DALI command translation and internal PSoC blocks to generate synchronized RGBW PWM waveforms. Use Value: Enables DALI-2 compliance without external transceiver; 32-bit PWM resolution ensures smooth 0.1% dimming steps; built-in CRC prevents misconfiguration during firmware updates. |
| Industrial Machine Status Lighting | Residential Smart Home Lighting |
Use Scenario: Embedding status-indicating LEDs into CNC machine panels, communicating operational state (run/idle/error) over 24V DC control wiring. IC Role / Device Role / Timing Role: Low-voltage PLC node - transmits status packets via 24V DC powerline and drives local indicator LEDs with flicker-free PrISM™ modulation. Use Value: Uses same wiring as machine power supply - avoids adding CAN or RS-485; CSMA prevents message loss during motor startup transients. | Use Scenario: Controlling distributed LED strips in homes using existing 110V AC wiring, with smartphone app integration via gateway node.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PLC + LED controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST7580 + STLD40 | Separate PLC modem IC + standalone LED driver - no integrated processor or PSoC resources | Requires external MCU for protocol stack and LED control logic - increases PCB area and firmware complexity | Preferred when modularity and independent upgrade paths for PLC and LED functions are required |
| TI TSS721A + TLC5940 | Dedicated narrowband PLC transceiver + 16-channel LED driver - no embedded network stack or PrISM™ modulation | Lacks integrated OSI Layers 2–4; requires host to implement CSMA, addressing, and packet retransmission logic | Chosen for cost-sensitive designs where only basic unidirectional PLC control is needed |
Compared with ST7580+STLD40 and TSS721A+TLC5940, the CY8CLED16P01-48LTXIT delivers single-chip integration of PLC PHY, full network protocol, and advanced LED control - reducing component count by ≥3, eliminating external protocol firmware development, and enabling EMI-compliant lighting without discrete spread-spectrum circuitry.

FAQ
What powerline voltage ranges does the CY8CLED16P01-48LTXIT support?
The CY8CLED16P01-48LTXIT supports 110V/240V AC and 12V/24V AC/DC powerlines via external coupling circuits. Reference designs comply with FCC Part 15 (North America) and CENELEC EN 50065-1:2001 (Europe). Its FSK PHY operates independently of line voltage - only the external coupling network must be adapted for specific voltage classes and regulatory limits.
Does the device support DALI or DMX512 natively?
The CY8CLED16P01-48LTXIT does not integrate native DALI or DMX512 physical layer transceivers, but its programmable PSoC digital blocks can implement DALI frame generation and DMX512 UART timing. Application notes and reference code are provided by Cypress for configuring GPIO pins and timers to meet DALI-2 timing specs and DMX512 break/space requirements.
How is LED dimming resolution achieved across 16 channels?
Each of the 16 LED channels supports programmable PWM resolution from 8 to 32 bits via the PSoC's digital timer/PWM blocks. Higher resolution (e.g., 24–32 bits) enables sub-0.1% dimming steps for architectural lighting, while lower resolution (8–16 bits) optimizes CPU load for fast-response status indicators - all configured dynamically through I²C register writes.
Is the 64-bit physical address factory-programmed or user-configurable?
The 64-bit physical address is factory-laser-trimmed and permanently stored in on-chip ROM - it cannot be overwritten or modified by firmware. This ensures globally unique node identification for secure network commissioning and prevents address conflicts in large-scale deployments, even when logical addresses are reused across subnets.
