Product introduction

71M6534HEnergy meter IC

description

Teridian's 71M6533 ™and 71M6534 are third-generation multiphase metering systems with 8051-compatible microcontroller cores, low-power RTCs, flash memory, and LCD driver chips (SoCs) at 10MHz. Single converter technology with 22-bit Δ-ΣADC, 7 analog inputs, digital temperature compensation, precision voltage reference, 32-bit calculation engine (CE) ® supports a wide range of metrology applications with minimal external components.

The 71M6533 and 71M6534 add several new features to Teridian's flagship 71M6513 Multiphase Meter, including an SPI interface, with Higher processing and sampling rates and larger memory provide a powerful metrology platform for commercial and industrial meters, with up to 0.2-class accuracy.

ICE and a complete array of development tools, programming libraries and reference designs enable square meters to meet all ANSI and IEC energy metering standards worldwide rapidly evolving and certifying.
