71M6521DE/71M6521FE  
Energy Meter IC  
DATA SHEET  
JANUARY 2008  
FEATURES  
GENERAL DESCRIPTION  
< 0.4% Wh accuracy over 2000:1 current range  
and over temperature  
Exceeds IEC62053 / ANSIC12.20 standards  
Voltage reference < 40ppm/°C  
Four sensor inputs—VDD referenced  
Low jitter Wh and VARh pulse test outputs  
(10kHz maximum)  
The TERIDIAN 71M6521DE/FE is a highly integrated SOC with an MPU  
core, RTC, FLASH and LCD driver. TERIDIAN’s patented Single Converter  
Technologywith 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 re-  
sidential 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 IC supports 2-  
wire, 3-wire and 4-wire single-phase and dual-phase residential metering  
along with tamper-detection mechanisms.  
Pulse count for pulse outputs  
Four-quadrant metering  
Tamper detection  
Maximum design flexibility is provided by multiple UARTs, I2C, μWire, up to  
18 DIO pins and in-system programmable FLASH memory, which can be  
updated with data or application code in operation.  
Neutral current with CT or shunt  
Line frequency count for RTC  
Digital temperature compensation  
Sag detection for phase A and B  
Independent 32-bit compute engine  
46-64Hz line frequency range with same  
calibration  
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 stan-  
dards.  
Phase compensation (±7°)  
Battery backup for RTC and battery monitor
