3-Phase Energy Meter IC
DATA SHEET
SEPTEMBER 2011
GENERAL DESCRIPTION
The 71M6513 is a highly integrated system-on-chip SoC with an MPU core,
real-time clock (RTC), flash, and LCD driver. Our Single Converter
Technology® with a 21-bit delta-sigma ADC, six analog inputs, digital tem-
perature compensation, precision voltage reference, and 32-bit computation
engine (CE) supports a wide range of poly-phase 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.
Maximum design flexibility is supported with multiple UARTs, I2C, a power-
fail comparator, a 5V LCD charge pump, up to 22 DIO pins, and an in-
system programmable flash. The device is offered in high (0.1%) and
standard (0.5%) accuracy versions for multifunction residential/commercial
meter applications requiring multiple voltage/current inputs and complex
LCD or DIO configurations.
A complete array of ICE and development tools, programming libraries and
reference designs enable rapid development and certification of meters that
meet most demanding worldwide electricity metering standards.

71M6513/71M6513H
3-Phase Energy Meter IC
DATA SHEET
SEPTEMBER 2011
With all switches set to the “B” position by applying the inverted CROSS signal, the output voltage is:
Voutn – Voutp = G (Vinn – Vinp + Voff) = G (Vinn – Vinp) + G Voff, or
Voutp – Voutn = G (Vinp – Vinn) - G Voff
Thus, when CROSS is toggled, e.g. after each multiplexer cycle, the offset will alternately appear on the output as positive and
negative, which results in the offset effectively being eliminated, regardless of its polarity or magnitude.
The Functional Description Section contains a chapter with a detailed description on controlling the CHOP_EN register.
Temperature Sensor
The 71M6513/6513H includes an on-chip temperature sensor implemented as a bandgap reference. It is used to determine
the die temperature The MPU may request an alternate multiplexer cycle containing the temperature sensor output by
asserting MUX_ALT.
The primary use of the temperature data is to determine the magnitude of compensation required to offset the thermal drift in
the system (see section titled “Temperature Compensation”).
The zero reference for the temperature sensor is VBIAS.
V3
V3 is an additional analog monitor input that can be used for analog measurements, such as neutral current. It is sampled
when the multiplexer performs an alternate multiplexer cycle. The zero reference for the V3 input is VBIAS.
V3 is also routed into the comparator block where it is compared to VBIAS. Comparator interrupts should be disabled when
the V3 input is used for analog measurements.
Functional Description
The AFE functions as a data acquisition system, controlled by the MPU. The main signals (IA, VA, IB, VB, IC, VC) are
sampled and the ADC counts obtained are stored in CE RAM where they can be accessed by the CE and, if necessary, by the
MPU. Alternate multiplexer cycles are initiated less frequently by the MPU to gather access to the slow signals, temperature
and V3.
