Product Brief
71M6513
71M6513H
Teridian Semiconductor’s Power Meter ICs
The Teridian 71M6513 is a highly integrated SOC with an MCU core, RTC, FLASH and LCD
driver. Teridian’s Single Converter Technology
™
with a 21bit 2nd order delta-sigma ADC,
6 analog inputs, digital temperature compensation, precision voltage reference and 32 bit
computation engine supports 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, I
2
C, 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 unprec-
edented cost structure for high volume applications. The device is offered in high (0.1%) and
low (0.5%) accuracy versions for multifunction 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 worldwide
electricity metering standards.
