FEATURES
•
< 0.4% Wh accuracy over industrial
temperature and 2000:1 current range
•
Four analog inputs
The new 71M6521 product family represents Teridian’s second
generation electricity metering technology for cost sensitive
residential applications. This SOC device is footprint compatible
with 71M6511, integrates AFE, MCU, RTC, FLASH and LCD driver
but offers lower cost 8/16/32 KB FLASH options, more I/O,
advanced power management and tamper detection. Teridian’s
patented Single Converter Technology
TM
with a 22bit 2
nd
order
delta-sigma converter, 4 analog inputs, digital temperature
compensation, voltage reference and flexible 32-bit computation
engine meet all current and evolving metering requirements
worldwide with minimal external components.
Low system cost is supported with 2 UARTs, I C/µWire EEPROM
interface, battery monitor, power fail monitor, neutral current or
magnetic tamper detection, program/data FLASH, mask ROM
option and operation with capacitive power supply.
Teridian’s large portfolio of solutions for residential, commercial and
industrial metering offers OEMs a comprehensive array of ICs,
tools, reference designs and above all a unique ability to
differentiate their products in the market.
