ATPL220A-A1U-Y

Overview

The ATPL220A-A1U-Y is a PRIME-compliant power line carrier modem designed for PLC base node implementation. It features a 97-carrier OFDM architecture supporting selectable baud rates from 21400 to 128600 bps with differential BPSK, QPSK, and 8-PSK modulations. The device integrates 32 Kbytes of on-chip SRAM, automatic gain control, embedded DMAs, Viterbi decoding, CRC verification, and 128-bit AES encryption. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 120-lead LQFP package measuring 14 x 14 mm with a 0.4 mm pitch.

Procurement Notes

Verify the ordering code ATPL220A-A1U-Y against official Microchip or Atmel documentation to confirm the specific package type, temperature grade, and shipping carrier option. Ensure that the component meets all applicable RoHS compliance requirements before integration into final designs.

Selection Notes

Select this component for applications requiring PRIME standard compliance on 50 or 60 Hz power lines. It is suitable for mono-phase injection or multi-phase MIMO configurations when combined with additional units. Ensure the host microcontroller supports SPI interface management for upper layer protocol handling.

Part Context

This part belongs to the ATPL220A family of Power Line Communications ASICs manufactured by Atmel (now Microchip Technology). It is specifically engineered as a PHY layer modem for Base Nodes, relying on an external MCU for MAC and network layer processing.

Replacement Considerations

Consult official Microchip documentation for verified substitute part numbers. Do not assume functional equivalence with other PLM devices without cross-referencing pinouts, electrical specifications, and protocol compliance.
