ATPL250A-AKU-Y

Application Specific Microcontrollers Overview

The ATPL250A-AKU-Y is a G3-PLC modem designed for power line communication applications. It implements G3 CENELEC-A, FCC, and ARIB profiles compliant with ITU-T G.9903 standards. The device features an embedded PLC Analog Front End (AFE) and requires only an external Class D Line Driver for signal injection. It operates on a 3.0V to 3.6V supply voltage (VDDIO) within an industrial temperature range of -40°C to +85°C. Communication with an external microcontroller is managed via a 4-line SPI interface and an interrupt line. The component is housed in an 80-lead LQFP package.

Application Specific Microcontrollers Feature Summary

• Implements G3-PLC coherent and differential modulation schemes for 50 Hz and 60 Hz mains networks.
• Includes Automatic Gain Control (AGC) and continuous amplitude tracking for signal reception.
• Features an embedded Zero Cross Detector supporting 50 Hz and 60 Hz detection with ±10% error tolerance.
• Provides an 80-lead LQFP package with Green compliance.

Application Specific Microcontrollers Applications

• Smart Metering systems including Smart Meters and Data Concentrators.
• Home and Building Energy Management Systems.
• Industrial and Home Automation control networks.
• Solar Energy monitoring and Plug-in Hybrid Electric Vehicle (PHEV) Charging Stations.

Application Specific Microcontrollers Procurement Notes

Verify the ordering suffix 'Y' corresponds to the Tray shipping carrier option as specified in the datasheet. Confirm that the Industrial temperature grade (-40°C to +85°C) matches the system requirements. Ensure the external MCU supports the required 3.3V logic levels for the SPI interface. Check moisture sensitivity level handling procedures prior to soldering.

Application Specific Microcontrollers Selection Notes

Select this component when a dedicated G3-PLC PHY layer is required for Smart Grid applications. An external microcontroller must be available to run the G3 PHY layer library and manage the device via SPI. Design the PCB layout to separate digital (GND) and analog (AGND) grounds to minimize interference. Ensure the external crystal oscillator meets the ±25 ppm stability requirement for transmit frequency derivation.

Application Specific Microcontrollers Part Context

The ATPL250A belongs to the Atmel Power Line Communications Device family. The specific suffix '-AKU-Y' denotes the 80-lead LQFP package, Lead-free construction, Industrial temperature rating, and Tray packaging format. This part is intended to be bundled with an external MCU rather than operating as a standalone processor.

Application Specific Microcontrollers Replacement Considerations

The ATPL250A-AKU-R is a functionally identical alternative offered in Tape and Reel packaging instead of Tray. Verify pinout compatibility if substituting between different package types within the same family.
