Teridian SoC tailored for polyphase power meters

Touted to be the world's first true SoC for industrial poly-phase power meters, the new 71M6513H SoC from Teridian Semiconductor Corp. integrates a 21 bit delta-sigma-delta converter, 32-bit compute engine, MCU, RTC, LCD driver and ultra-precision voltage reference, and provides better than 0.1 percent accuracy with only a few low cost external components.
"Utilizing Teridian's patent pending Single Converter Technology and digital temperature compensation, the 71M6513H achieves 10ppm/¢XC accuracy only previously possible with multiple chips and costly external components," shared Kourosh Boutorabi, product line manager for metering products.

The 71M6513H can perform many standard and custom functions including active energy, apparent energy, voltage rms, current rms, as well as waveform samples data for optional external processing. It consumes <30mW in mission and 13£gW in battery modes, and includes 64KB of MCU program/data storage, 7KB RAM, RTC, 5V LCD boost, 2+ UARTs and a I2C interface.

Pricing for the new power meter IC starts at $4.95 in 10,000 unit quantities. It can be produced in FLASH and ROM versions and is already available for sampling in 100-pin epLQFP packages.
