Product details
Overview
CY8CPLC10-28PVXI from Cypress Semiconductor is an integrated Powerline Communication (PLC) modem IC combining FSK PHY and full OSI Layers 2–4 network protocol stack; supports 2400 bps bidirectional half-duplex communication over AC/DC powerlines; features 8-bit CRC error detection, I²C host interface (50/100/400 kHz), and CENELEC EN50065-1/FCC Part 15-compliant operation in lighting control and smart energy systems.
For engineers reviewing the CY8CPLC10-28PVXI datasheet, CY8CPLC10-28PVXI pinout, CY8CPLC10-28PVXI application, or CY8CPLC10-28PVXI equivalent, key selection considerations include FSK carrier frequencies (131.8/133.3 kHz), logical/physical addressing modes (8-/16-/64-bit), CSMA timing parameters, PLT packet structure, and coupling circuit interface requirements for 110–240 VAC or 12–24 VAC/DC lines.
Technical Context
The CY8CPLC10-28PVXI implements a complete PLC transceiver solution with on-chip FSK modem PHY operating at 131.8 kHz (logic '1') and 133.3 kHz (logic '0'), supporting configurable 130.4 kHz logic '1' for wider bandwidth. It integrates digital transmitter/receiver blocks, correlator-based demodulation, hysteresis comparator, and programmable gain amplifier optimized for lossy powerline channels.
Its embedded Powerline Network Protocol handles data link, network, and transport layers-including bidirectional half-duplex operation, Carrier Sense Multiple Access (CSMA) with 85–115 ms random backoff, Band-In-Use (BIU) detection threshold (86 dBuVrms), 8-bit CRC, sequence numbering, and acknowledged/unacknowledged transmission modes.
Key Specifications

|---|---|
| Data Rate | 2400 bps - fixed baud rate enabling deterministic timing for time-critical metering and control applications. |
| FSK Frequencies | 131.8 kHz (logic '1') / 133.3 kHz (logic '0') - narrowband CENELEC-compliant carriers minimizing spectral interference in 125–140 kHz band. |
| I²C Support | 50 / 100 / 400 kHz - enables direct integration with PSoC®, ARM Cortex-M, or legacy 8-bit microcontrollers without clock stretching. |
| Addressing Modes | 8-bit logical (256 nodes), 16-bit extended (65,536 nodes), 64-bit physical (2⁶⁴ nodes) - scalable topology support for residential to industrial networks. |
| PLT Packet Size | 6–53 bytes (6-byte header + 0–31-byte payload + 1-byte CRC) - balances overhead efficiency and payload flexibility for command/control messaging. |
| Operating Temp | –40°C to +85°C - qualified for deployment in outdoor meters, industrial signage, and unregulated indoor lighting enclosures. |
| Supply Voltage | 3.0 V to 5.5 V - compatible with standard 3.3 V or 5 V system rails and tolerant of brown-out conditions during AC line fluctuations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Powerline Communication modem applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST7580 | OFDM-based PHY (not FSK); supports up to 13.2 kbps; requires external microcontroller for full protocol stack. | Better suited for high-throughput smart grid AMI; lacks integrated network layer-increases host firmware burden. | Select when higher bandwidth and OFDM robustness in noisy medium-voltage grids outweigh added software development cost. |
| MAX2990 | FSK PHY only (no embedded protocol stack); requires external EEPROM and host MCU to implement addressing, CSMA, and CRC. | Targeted at custom protocol implementations; no native support for CENELEC-compliant timing or BIU detection. | Select when proprietary network architecture or legacy protocol migration mandates full PHY-level control. |
Compared with ST7580 and MAX2990, CY8CPLC10-28PVXI delivers turnkey interoperability with minimal host processing-its integrated FSK PHY and full OSI L2–L4 stack reduce BOM count, accelerate certification, and simplify compliance testing for lighting and metering OEMs.

FAQ
What external components are mandatory for CY8CPLC10-28PVXI to operate on 230 VAC powerlines?
A compliant 230 VAC coupling circuit is mandatory and includes: a 32.768 kHz crystal (XTAL_IN/XTAL_OUT), 24 MHz external oscillator (EXTCLK), isolation transformer, HF band-pass filter (125–140 kHz), programmable gain amplifier, and low-pass filter (7.5 kHz cutoff). Cypress provides reference schematics (e.g., AN76245) specifying exact passive values and safety-rated components meeting EN50065-1 creepage/clearance rules.
Does CY8CPLC10-28PVXI support automatic retransmission on packet failure?
Yes-when configured in acknowledged mode, the CY8CPLC10-28PVXI automatically retries transmission up to TX_Retry times (configurable register) upon missing acknowledgment. Retransmission uses the same sequence number and occurs after CSMA backoff delay (85–115 ms), ensuring deterministic recovery without host intervention.
Can the FSK carrier frequencies be modified beyond the default 131.8/133.3 kHz pair?
Yes-the logic '1' frequency can be configured to 130.4 kHz via internal register setting, widening the FSK separation to 2.9 kHz (vs. 1.5 kHz default) for improved noise immunity in high-interference environments, while remaining within CENELEC's 125–140 kHz allocated band.
Is there hardware support for secure authentication or encryption in CY8CPLC10-28PVXI?
No-CY8CPLC10-28PVXI does not include cryptographic accelerators or secure key storage. Security must be implemented at the application layer on the external host MCU (e.g., AES-128 encryption of payload before I²C transfer) or via external secure elements interfaced alongside the CY8CPLC10.
