71M6511H

The Teridian 71M6511 is a highly integrated SOC with an MCU core, RTC, FLASH and LCD driver. Teridian's Single Converter Technology™ 71M6511 with a 21bit 2nd order delta-sigma ADC, 3 analog inputs, digital temperature compensation, precision voltage reference and 32 bit computation engine supports a wide range of residential metering applications and sensor configurations with only a few 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 of 71M6511 is supported with multiple UARTs, I2C, power fail comparator, 5V LCD charge pump, up to 12 DIO pins and in-system programmable FLASH which can be updated with data or application code in operation. Easy conversion to ROM offers unprecedented cost structure for high volume applications.The device is offered in 0.1% and 0.5% accuracy versions.

A complete array of ICE and development tools, programming libraries and reference designs enable rapid development and certification of TOU, AMR and Prepay meters that meet worldwide electricity metering standards.
