ATPL210A-A1U-Y

Application Specific Microcontrollers Overview

The ATPL210A-A1U-Y is a PRIME-compliant Power Line Communications System on Chip manufactured by Microchip Technology (formerly Atmel). It integrates an ADD8051C3A enhanced 8051 core with a full OFDM modem supporting 97 carriers for 50/60 Hz mains. The device features 32 Kbytes of on-chip SRAM, supports up to 256 Kbytes of external SRAM, and includes a Medium Access Controller with Viterbi decoding, CRC, and 128-bit AES encryption. Operating within an industrial temperature range of -40°C to +85°C, it utilizes a 120-lead LQFP package.

Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized distribution channels due to historical manufacturer transitions. Confirm RoHS compliance status and check current production lifecycle status, as the original datasheet indicates an initial release date of March 2012. Ensure supply chain continuity for the specific 120-lead LQFP package variant.

Application Specific Microcontrollers Selection Notes

Select this component for designs requiring strict adherence to PRIME specifications in narrowband power line communication environments. The integrated MAC and modem reduce CPU load, making it suitable for metering applications where computational efficiency is critical. Ensure the design accommodates the 120-lead LQFP footprint and supports the required external memory interfaces if storage exceeds 32 Kbytes.
