STreamPlug ST2100: broadband powerline communication SoC
  • active Active

The STreamPlug ST2100 device is the STMicroelectronics®“Broad Band Powerline Communication” (BB PLC) solution, based on the powerful ARM926EJ-S™ processor (up to 333 MHz), widely used in applications where high computation performance is required, such as consumer (“Home Area Network” or HAN), industrial and smart grid applications.

In addition, the STreamPlug ST2100 has a memory management unit (MMU) that allows virtual memory management - making the system compliant with the Linux®operating system. It also offers 16 Kbyte of data cache, 32 Kbyte of instruction cache, JTAG and ETM™ (Embedded Trace Macrocell™ ) for debug operations.

A large set of peripherals allows a wide flexibility of the usage of the system in most of the possible PLC broadband applications (indoor and outdoor).
