GENERAL DESCRIPTION
FEATURES
The 71M6543F, 71M6543H, 71M6543G, and 71M6543GH are
Teridian’s 4th-generation polyphase metering systems-on-chips
(SoCs) with a 5MHz 8051-compatible MPU core, low-power real-
time clock (RTC) with digital temperature compensation, flash
memory, and LCD driver. Our Single Converter Technology® with
a 22-bit delta-sigma ADC, seven analog inputs, digital metrology
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 71M6543F, 71M6543H, 71M6543G and 71M6543GH support
optional interfaces to the 71M6xx3 series of isolated sensors that
offer BOM cost reduction, immunity to magnetic tamper, and
enhanced reliability. The ICs feature ultra-low-power operation in
active and battery modes, 5KB shared RAM, and 64KB
(71M6543F, 71M6543H) or 128KB (71M6543G, 71M6543GH) of
flash memory, which can be programmed with code and/or data
during meter operation. High processing and sampling rates
combined with differential inputs offer a powerful metering platform
for commercial and industrial meters with up to class 0.2 accuracy
(71M6543H, 71M6543GH).
A complete array of code development tools, demonstration code,
and reference designs enable rapid development and certification of
meters that meet all ANSI and IEC electricity metering standards
worldwide.
