GENERAL DESCRIPTION

Power Meter IC
PRELIMINARY DATASHEET
SEPTEMBER 2004
FEATURES
The TDK 71M6513 is a highly integrated SOC with an MPU core,
RTC, FLASH and LCD driver. TDK’s patent pending Single Con-
verter Technology with a 21-bit delta-sigma ADC, 6 analog
inputs, digital temperature compensation, precision voltage
reference and 32-bit computation engine support a wide range of
polyphase metering applications with very few low cost external
components. A 32kHz crystal timebase 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,
power fail comparator, 5V LCD charge pump, up to 22 DIO pins and
in system programmable FLASH which can be updated with data or
application code in operation. Easy conversion to ROM offers un-
precedented cost structure for high volume applications. The device
is offered in high (0.1%) and low (0.5%) accuracy versions for multi-
function residential/commercial meter applications requiring multiple
voltage/current inputs, larger LCD or DIO features.
A complete array of ICE and development tools, programming
libraries and reference designs enable rapid development and
certification of meters that meet most demanding world wide
electricity metering standards.

Meter Equations
Compute Engine (CE) firmware for industrial configurations implements the equations in Table 1. The register
EQU (located in the I/O RAM) specifies the equation to be used based on the number of phases used for
metering. In case of single and two phase metering the unconnected inputs may be tied to V3P3A. The EQU
selection will enable the 71M6513 to calculate polyphase power measurement based on the type of service used.
Table 1 also states the sequence of the multiplexer.
