71M6521DE/DH/FE
Energy Meter ICs
DATA SHEET
GENERAL DESCRIPTION
The Teridian? 71M6521DE/DH/FE energy meter ICs are highly integrated
systems-on-a-chip (SoCs) with an MPU core, RTC, flash, and LCD driver.
The Single Converter Technology? with a 22-bit delta-sigma ADC, four
analog inputs, digital temperature compensation, precision voltage
reference, battery voltage monitor, and 32-bit computation engine (CE)
supports a wide range of residential metering applications with very few
low-cost external components. A 32kHz crystal time base for the entire
system and internal battery-backup support for RAM and RTC further
reduce system cost. The ICs support 2-wire, 3-wire, and 4-wire single-
phase and dual-phase residential metering along with tamper-detection
mechanisms.
Maximum design flexibility is provided by multiple UARTs, I 2 C,
MICROWIRE?, up to 18 DIO pins, and in-system programmable flash
memory, which can be updated with data or application code in operation.
A complete array of ICE and development tools, programming libraries, and
reference designs enable rapid development and certification of TOU,
AMR, and prepay meters that comply with worldwide electricity metering
standards.
