Smart Meters

Smart meters (digital electricity meters with integrated communication modules) that are increasingly installed in the world, must provide accurate meter reading, provisions for different communication systems and a high level of circuit integration. Toshiba offers total solutions for smart metering that encompass ARM Cortex™-M cores, metrology MCUs, communication MCUs and discrete components.
