General Description
The 71M6545T/71M6545HT metrology processors are
based on Maxim Integrated’s 4th-generation metering
architecture supporting the 71M6xxx series of isolated
current sensing products that offer drastic reduction in
component count, immunity to magnetic tampering, and
unparalleled reliability. The 71M6545T/71M6545HT inte-
grate our Single Converter Technology® with a 22-bit
delta sigma ADC, a customizable 32-bit computation
engine (CE) for core metrology functions, as well as a
user-programmable 8051-compatible application proces-
sor (MPU) core with 64KB flash and 5KB RAM.
An external host processor can access metrology func-
tions directly through the SPI interface, or alternatively
through the embedded MPU core in applications requir-
ing metrology data capture, storage, and preprocessing
within the metrology subsystem. In addition, the devices
integrate an RTC, DIO, and UART. A complete array of
ICE and development tools, programming libraries, and
reference designs enable rapid development and certi-
fication of meters that meet all ANSI and IEC electricity
metering standards worldwide.
The 71M6545T/71M6545HT operate over the industrial tem-
perature range and come in a 64-pin lead(Pb)-free package.
