ST2100TR

Overview

The ST2100TR is a broadband powerline communication (BB PLC) system-on-chip from the STMicroelectronics STreamPlug series. It integrates an ARM926EJ-S processor running up to 333 MHz with a configurable hardware engine for HomePlug AV, 1.0, and Green PHY standards. The device features an integrated analog front-end, Ethernet 10/100 MAC, USB 2.0, and cryptographic coprocessor. Operating at 1.2 V within -40°C to +85°C, it supports DDR/DDR2 memory and multiple interfaces including I2S, UART, and SPI. Packaged in a 373-TFBGA (12x12 mm), it targets high-performance audio/video streaming over power lines.
