Silergy Device Functions as a Completely Autonomous Metrology Processor in a 5x5mm 32-pin QFN package
Featuring Silergy’s proprietary Teridian power measurement technology, it can be combined with up to four analog front end (AFE) devices are supported, each utilizing an independent, robust capacitive-coupled digital interface. Each AFE supports two ADC channels (voltage and current) to form a highly accurate and fully isolated shunt-based meter.
The device functions as a completely autonomous metrology processor. A set of pre-processed metrology outputs can be obtained by the host by reading registers that are accessible though the SPI interface. Likewise, system parameters, such as the desired meter constant (Kh), calibration coefficients, sag threshold, and other parameters into the RAM of the SY7T625 by the host.
A powerful 24-bit Compute Engine and math accelerators implement the core requirements of high accuracy metering. Code images that cover most requirements of revenue metering are provided by
A sophisticated onboard clock management system provides an internal clock source and automatically accesses an optional external crystal if the highest accuracy timing is desired. An integrated hardware Watchdog Timer (WDT) is also included.
