The Teridian™ 71M6521DE/DH/FE series, including the 71M6521FE-IGT/F, are highly integrated systems-on-a-chip designed for residential energy metering applications. These ICs feature an MPU core, RTC, flash memory, and an LCD driver, supported by a 22-bit delta-sigma ADC and a 32-bit computation engine.
Key electrical specifications include an accuracy of up to 0.1% Wh over a 2000:1 current range and operation from 3V to 3.6V. The device supports both single-phase and dual-phase metering with measurement errors as low as 0.4%. It includes digital temperature compensation and a precision voltage reference with a temperature coefficient below 40 ppm/°C.
This IC is housed in a 64-LQFP package suitable for surface mounting. It operates within a temperature range of -40°C to 85°C. The 71M6521FE variant includes 32KB of flash memory and 2KB of MPU XRAM, along with two UARTs for IR and AMR communication. Battery backup support for the RTC and RAM is provided, with multiple low-power modes available.
The 71M6521FE-IGT/F is designed to support a wide range of residential metering applications, including TOU, AMR, and prepay meters, complying with worldwide electricity metering standards. Its integrated features reduce the need for external components, facilitating rapid development and certification.
