The IDT 90E46 is a single-phase SoC for smart meter designs, which integrates an energy metering analog front-end with a real-time clock, temperature sensor, LCD driver, and ARM Cortex M0 microprocessor.
The metering device is the latest member of IDT’s award-winning family and offers the industry’s widest dynamic range of 5000:1, which enables meter manufacturers to merge various meter types into one, thus simplifying the design and manufacturing process for meter makers and reducing the storage and management complexity for utilities. The high level of integration enables system designers to significantly simplify the hardware design and lower the bill-of-materials (BOM) cost.
The new IDT metering SoC is fully compliant with international (both IEC and ANSI) and Chinese standards, and meets or exceeds the requirements set forth by the State Power Grid Corporation of China (SGCC). The device features 128 kB of internal flash memory, enabling users to store large instruction sets for the integrated microprocessor.
