Using the SSI Interface with the 71M651X Energy Meter Chips

Abstract: The synchronous serial interface (SSI) provides a fast data stream directly from the computation-engine (CE) dynamic RAM (DRAM) of Teridian's single- and 3-phase energy-metering ICs to an external processor or data logger. Since any contiguous region of the DRAM can be selected as a data source, any type of data accessible to the CE is also easily accessible to the external processor. This article describes how to configure and use the SSI. It discusses SSI signals, SSI control registers, SSI timing, and considerations for the digital-signal processor (DSP) or data logger.
