GENERAL DESCRIPTION
The 71M6533 and 71M6534 are Teridian’s 3
rd
-generation poly-
phase metering SOCs with a 10MHz 8051-compatible MPU
core, low-power RTC, FLASH and LCD driver. Teridian’s pa-
tented Single Converter Technology® with a 22-bit delta-sigma
ADC, seven analog inputs, digital temperature compensation,
precision voltage reference and a 32-bit computation engine
(CE) supports a wide range of metering applications with very
few external components.
The 71M6533 and 71M6534 add several new features to Teri-
dian’s flagship 71M6513 poly-phase meters including an SPI in-
terface, advanced power management with <1 µA sleep cur-
rent, 4 KB shared RAM and 128 KB (71M6533/H, 71M6534) or
256 KB (71M6534H) Flash which may be programmed in the
field with new code and/or data during meter operation. Higher
processing and sampling rates and larger memory offer a po-
werful metering platform for commercial and industrial meters
with up to class 0.2 accuracy.
A complete array of ICE and development tools, programming
libraries and reference designs enable rapid development and
certification of meters that meet all ANSI & IEC electricity meter-
ing standards worldwide.
