ST2100

Overview

The ST2100 is a Broadband Powerline Communication (BB PLC) System on Chip from the STreamPlug series, manufactured by STMicroelectronics. It integrates an ARM926EJ-S processor running up to 333 MHz with a memory management unit for Linux compliance. The device supports HomePlug AV, 1.0, and Green PHY standards via configurable hardware engines. Key electrical parameters include a core voltage range of 1.08 V to 1.32 V, operating temperatures from -40°C to +85°C, and a data rate of 20 Mb/s. It is housed in a 373-TFBGA package.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and functional variations. Ensure the component meets RoHS requirements for the target market. Confirm moisture sensitivity levels and recommended reflow soldering profiles prior to assembly to prevent package damage during manufacturing.

Selection Notes

Select this component when high computational performance is required for PLC applications. The integrated MMU allows for complex operating systems like Linux. Verify that the system design accommodates the required DDR mobile or DDR2 memory interfaces and the specific voltage domains needed for the ARM core and peripherals.

Part Context

The ST2100 belongs to the STMicroelectronics STreamPlug family of broadband powerline communication solutions. It is designed to replace discrete PLC implementations by integrating the PHY, MAC, and application processor into a single chip, reducing board space and complexity for indoor and outdoor powerline networking devices.
