STMicroelectronics states that its ST2100 STreamPlug System-on-Chip (SoC) for smart-home and smart-energy applications is the world’s first intelligent-gateway SoC. The ST2100 STreamPlug combines a high-performance processing subsystem with Powerline Communication (PLC), security, and peripheral features to support hybrid networks utilizing popular wired and wireless standards. It is designed to support IEEE 1905.1 that enables customers to converge Ethernet, Wi-Fi and other networking standards in new gateway or hub designs. The ST2100 StreamPlug also supports popular PLC protocols such as HomePlug AV and HomePlug Green PHY, as well as IEEE 1901 Broadband Powerline connectivity.
ST’s collaboration with Tatung leveraging the ST2100 STreamPlug SoC has yielded innovations such as Tatung’s Gateway One home networking hub and other smart-energy devices. The Gateway One enables users to setup multi-bearer home networks combining Ethernet, WLAN, PLC and multimedia devices, greatly enhancing opportunities to improve energy efficiency, security, comfort and convenience throughout the home. Tatung’s Meter Bridge and Home-Area Network (HAN) Bridge enable multi-occupancy dwellings to benefit from smart-energy applications, while solving consumption and billing challenges. The M1i and M3 are intelligent devices that provide energy management as well as network connectivity for devices plugged into the AC line. The M1i is optimized for industrial applications, while the M3 is featured for domestic use including charging plug-in electric vehicles.
The ST2100 STreamPlug SoC application processor features the ARM926EJ-S core operating at 330MHz, and provides an external memory-management subsystem. Also integrated on-chip is a complete PLC modem and analog front end, USB2.0 and Ethernet interfaces, a color-LCD controller and a dedicated security engine supporting advanced cryptography algorithms such as AES, DES/3DES and IPSec.
