GENERAL DESCRIPTION

The TERIDIAN 71M6511 is a highly integrated SOC with an MPU core,

RTC, FLASH and LCD driver. TERIDIAN’s patented Single Converter

Technology with a 22-bit delta-sigma ADC, 3 analog inputs, digital

temperature compensation, precision voltage reference and 32-bit

computation engine (CE) supports a wide range of single-phase metering

applications with very few low cost external components. A 32kHz crystal

time base 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

fail comparator, a 5V LCD charge pump, up to 12 DIO pins and an in-

system programmable FLASH. The device is offered in high (0.1%) and

standard (0.5%) accuracy versions for multifunction residential/commercial

meter applications requiring multiple voltage/current inputs and complex

LCD or DIO configurations.

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.
