GENERAL DESCRIPTION
71M6513/71M6513H
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.

FUNCTIONAL DESCRIPTION
71M6513/71M6513H
Power Meter IC
PRELIMINARY DATASHEET
SEPTEMBER 2004
The TDK 71M6513 single chip polyphase meter integrates all primary functional blocks required to implement a
solid-state electricity meter. Included on chip are an analog front end (AFE), a digital computation engine, an
8051-compatible microprocessor which executes one instruction per clock cycle, an independent 32-bit compute
engine (CE), a voltage reference, a temperature sensor, LCD drivers, RAM, FLASH memory, a real time clock
(RTC), and a variety of I/O pins. Various current sensor technologies are supported including Current
Transformers (CT), Resistive Shunts, and Rogowski (di/dt) Coils.
In a typical application, the 71M6513 sequentially samples the voltage inputs on pins IA, VA, IB, VB, IC, VC and
performs calculations to measure active power (Wh), reactive power (VARh), A2h, and V2h for four quadrant
metering. These and other measurement functions which are primarily executed on the internal 32-bit compute
engine (CE) are provided as part of TDK’s standard library. Standard ANSI “C” 80515 application programming
interface library is available to help reduce design cycle.
In addition to advanced measurement functions, the real time clock function allows the device to record time of
use (TOU) metering information for multi-rate applications. Measurements can be displayed on either 3V or 5V
LCD commonly used in low temperature environments. Flexible mapping of LCD display segments will facilitate
integration with any LCD format. Design trade-off between number of LCD segments vs. DIO pins can be
implemented in software to accommodate various requirements.
In addition to the temperature-trimmed ultra-precision voltage reference, the on-chip digital temperature
compensation mechanism includes a temperature sensor and associated controls for correction of unwanted
temperature effects on measurement and RTC accuracy. Temperature dependent external components such as
crystal oscillator and current transformers (CT) can be characterized and their correction factors can be
programmed to produce electricity meters with exceptional accuracy over the industrial temperature range.
One of the two internal UARTs is adapted to support an Infrared LED with internal drive and sense amplification
but it can also function as a standard UART. In addition to the two hardware UART modules, customers can
implement a third UART function using a Bit-Bang scheme through two DIO pins. This flexibility makes it possible
to implement AMR meters with two ports plus a third Infrared interface. A detailed description of various functions
follows:
