GENERAL DESCRIPTION

FEATURES

The 71M6515H is a high-accuracy analog front end

(AFE) IC that provides measurements for four-

quadrant 3-phase metering. The combination of a

21-bit sigma-delta A/D converter with a six-input

analog front end, a thermally compensated high pre-

cision reference and a compute engine results in

high accuracy and wide dynamic range. Patented

Single-Converter Technology™ reduces cross talk

and cost. This IC also provides RTC and battery

backup for time-of-use (TOU) metering.

High Accuracy

• < 0.1% Wh accuracy over temperature and

2000:1 range

• Exceeds IEC62053/ANSIC12.20 specifications.

• Precision ultra-stable voltage reference

(10PPM/°C)

• Single Converter Technology™ reduces cross

talk and power consumption

• Six sensor inputs—referenced to V3P3

• Compatible with CTs, resistive shunts and

Rogowski Coil sensors

• -90dB THD max.

• Digital temperature compensation

• Sag detection

Battery

• Measures Wh, VARh, VAh, Vrms, Irms, V-to-V

phase and load angle on each phase

• Four-quadrant metering.

• Four low-jitter pulse outputs from selectable

measurements

• Four pulse count registers

• Selectable default status for pulse pins

• Same calibration data for 46Hz to 64Hz line

frequency

Battery Backup

TERIDIAN 71M6515H

• Protects accumulated data and powers real time

clock during power supply outage

• Compatible with Li-ion, NiCd, or super-capacitor

• Battery backup current 2µA typical at 25°C

Figure 1: Meter block diagram

As shown in the block diagram (Figure 1), the host

processor communicates with the 71M6515H

through a UART interface using the programmable

IRQZ interrupt. The 71M6515H calculates and accu-

mulates meter measurements for each accumulation

interval. A high-speed synchronous serial port (SSI)

is provided to facilitate high-end metering. Integrated

rectifying functions on the battery backup circuit

enable minimal external component usage and

minimum back-up current. Also, eight multi-purpose

pins are provided for control of peripherals.

External Data Interface

• UART Control Interface, two selectable data

rates

• 8 general-purpose I/O pins with alarm capability

• 5 or 10MHz selectable high speed synchronous

serial output for DSP interface

• IRQ output signal for alarms and end of measure-

ment intervals.

• Alarms on voltage sag, over-voltage, over-current

Low System Cost

• Power Consumption 30mW @ 3.3V typical

• Real-time clock with temperature compensation

• Built-in power fault detection

• Single 32kHz crystal time base

• Single-supply operation (3.3V)

• 64-lead LQFP package
