The solution is the first of several targeting systems architects and designers who develop solutions for the Internet of Things (IoT). The initial collaboration, which focuses on the module for electric vehicle supply equipment (MEVSE) featuring vehicle-to-grid (V2G) communication and support for a wide range of network and application protocols from Tatung, utilizes the Microsemi Le87501 PLC line driver and the ST2100 STreamPlug SoC from ST, along with a proprietary state Machine, event-driven- (SMED) based digital power controller and is supported by the OpenV2G software stack.

The Microsemi Le87501 PLC drivers are based on Microsemi’s proprietary high-speed, high-voltage bipolar process technology, which enables significant performance and cost savings over currently used technologies. Microsemi’s industry-leading devices have also been selected by ST for reference designs for the company’s ST2100 STreamPlug SoC products used in applications where high integration levels and computation performance are required, such as consumer home area networks (HANs), industrial and smart-grid applications.

The solution is the first collaboration between ST and Microsemi targeting IoT. Microsemi and ST are enabling additional capabilities with the use of the Microsemi Timberwolf audio processors for command and control as well as audio sensing. The Timberwolf DSP platform enables Microsemi to apply its extensive expertise and leadership in voice communications to bridge into new and emerging hands-free applications that require clear speech, free of noise and echo.

The world’s first intelligent-gateway SoC, ST’s ST2100 STreamPlug combines a high-performance processing subsystem with power line communication (PLC), security and peripheral features to support hybrid networks utilizing popular wired and wireless standards, including HomePlug® AV and HomePlug Green PHY. The STreamPlug SoC also integrates a PLC modem and analog front end.

The Le87501 is a single channel line driver designed to work in HomePlug Alliance HPAV2 systems. When enabled, the operation can be set to full, 90 percent or 80 percent power. The Le87501 delivers superior performance and can drive a line impedance of 100ohms down to 12 ohms through a proper transformer. In addition, the Le87501 features a standby state which forces the driver into a long-term sleep mode.
