71M6531D/F, 71M6532D/F  
Energy Meter IC  
DATA SHEET  
Simplifying System IntegrationTM  
19-5374; Rev 1; 4/13  
FEATURES  
GENERAL DESCRIPTION  
Wh accuracy < 0.1% over 2000:1 current  
The 71M6531D/F and 71M6532D/F are highly  
range  
integrated SOCs with an MPU core, RTC, FLASH and LCD  
driver. The patented Single Converter Technology® with a  
22-bit delta-sigma ADC, four analog inputs, digital tempera-  
ture 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.  
Exceeds IEC62053/ANSI C12.20 standards  
Four sensor inputs  
Low-jitter Wh and VARh plus two additional  
pulse test outputs (4 total, 10 kHz maximum)  
with pulse count  
Four-quadrant metering  
Tamper detection (Neutral current with CT,  
Rogowski or shunt, magnetic tamper input)  
A 32-kHz 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, and 3-wire single-phase and  
dual-phase residential metering along with tamper-detection  
mechanisms. The 71M6531D/F offers single-ended inputs for  
two current channels and two single-ended voltage inputs.  
The 71M6532D/F has two differential current inputs and three  
single-ended voltage inputs.  
Maximum design flexibility is provided by multiple UARTs, I2C,  
μWire, up to 21 DIO pins and in-system programmable FLASH  
memory, which can be updated with data or application code  
in operation.  
Line frequency count for RTC  
Digital temperature compensation  
Sag detection for phase A and B  
Independent 32-bit compute engine  
46-64 Hz line frequency range with same  
calibration. Phase compensation (± 7°)  
Three battery modes with wake-up on timer  
or push-button:  
BROWNOUT Mode (52 µA typ.)  
LCD Mode (21 µA typ., DAC active)  
SLEEP Mode (0.7 µA typ.)  
Energy display during mains power failure  
39 mW typical consumption @ 3.3 V, MPU  
clock frequency 614 kHz  
22-bit delta-sigma ADC with 3360 Hz or  
2520 Hz sample rate  
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.  
8-bit MPU (80515),1 clock cycle per instruction,  
10 MHz maximum, with integrated ICE for  
debug  
RTC for TOU functions with clock-rate adjust
