71M6531D/F, 71M6532D/F

Energy Meter IC

DATA SHEET

Simplifying System Integration^TM

October 2009

FEATURES

GENERAL DESCRIPTION

• Wh accuracy < 0.1% over 2000:1 current

range

• 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

The Teridian 71M6531D/F and 71M6532D/F are highly inte-

grated SOCs with an MPU core, RTC, FLASH and LCD driver.

Teridian’s patented Single Converter Technology® with a 22-bit

delta-sigma ADC, four analog inputs, digital temperature com-

pensation, 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.

• Four-quadrant metering

• Tamper detection (Neutral current with CT,

Rogowski or shunt, magnetic tamper input)

• 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:

A 32-kHz crystal time base for the entire system and internal bat-

tery 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 sin-

gle-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.

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

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.

• 22-bit delta-sigma ADC with 3360 Hz or

2520 Hz sample rate

• 8-bit MPU (80515), 1 clock cycle per in-

struction, 10 MHz maximum, with integrated

ICE for debug

LOAD

• RTC for TOU functions with clock-rate adjust

• Hardware watchdog timer, power fail monitor

• LCD driver with 4 common segment drivers:

Up to 156 (71M6531D/F) or 268 pixels

(71M6532D/F)

• Up to 22 (71M6531D/F) or 43

(71M6532D/F) general-purpose I/O pins.

Digital I/O pins compatible with 5 V inputs

• 32 kHz time base

• High-speed slave SPI interface to data RAM

• Two UARTs for IR and AMR, IR driver with

modulation

• FLASH memory with security and in-system

program update:

128 KB (71M6531D/32D)

256 KB (71M6531F/32F)

• 4 KB MPU XRAM

• Industrial temperature range

• 68-pin QFN package for 71M6531D/F pin-

compatible with 71M6521, 100-pin LQFP

package for 71M6532D/F, lead free
