The 71M6533-IGTR/F is an energy meter IC in 100 pin LQFP package. This is an 3rd generation polyphase metering systems-on-chip (SoC) with a 10MHz 8051-compatible MPU core, low power RTC, flash and LCD driver. The Single Converter Technology with a 22bit delta-sigma ADC, seven analogue inputs, digital temperature compensation, precision voltage reference and a 32bit computation engine (CE) supports a wide range of metering applications with very few external components. This IC adds several new features to the Teridian flagship 71M6513 polyphase meters, including an SPI interface, advanced power management with < 1μA sleep current, 4KB shared RAM and 128KB flash. It can be programmed in the field with new code and/or data during meter operation. Higher processing and sampling rates and larger memory offer a powerful metering platform for commercial and industrial meters with up to class 0.2 accuracy.
