71M6515H

Energy Meter IC

DATA SHEET

JULY 2011

GENERAL DESCRIPTION

The 71M6515H is a high-accuracy analog front-end

(AFE) IC that provides measurements for 3-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-precision

reference, and a compute engine results in high

accuracy and wide dynamic range. Our Single

Converter Technology® reduces cross talk and cost.

This IC also provides RTC and battery backup for

time-of-use (TOU) metering.

FEATURES

Battery Backup



Powers real-time clock during power supply

outage



Compatible with Li-ion, NiCd, or super capacitor



Battery backup current 2µA typical at 25°C

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

measurement intervals



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 multipurpose

pins are provided for control of peripherals.
