GENERAL DESCRIPTION
FEATURES
ꢀ < 0.1% Wh accuracy over 2000:1
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.
range (71M6513H version)
ꢀ < 0.5% Wh accuracy over 2000:1
range (71M6513 version)
ꢀ Exceeds IEC62053 / ANSIC12.20.
ꢀ Voltage reference < 10ppm/°C spec
(71M6513H version), <50ppm/°C
(71M6513 version)
ꢀ Six sensor inputs - VDD referenced
ꢀ Four quadrant metering
ꢀ Voltage angles -- phase sequence
ꢀ Digital temperature compensation
ꢀ 21-bit delta-sigma ADC
ꢀ Independent 32bit compute engine
ꢀ Low jitter Wh/ VARh pulse outputs
ꢀ 40-70Hz line frequency range
ꢀ Phase compensation (±7°)
ꢀ Battery Backup for RAM and RTC
ꢀ 29mW @3.3V, 7.2µW back up.
ꢀ Flash memory option with security
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.
