Hot-selling and scarce 71M6511-IGT/F Single-Phase Energy Meter IC QFP64 spot stock

Product Descriptions

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, I2 C, a power fail comparator, a 5V LCD charge pump, up to 12 DIO pins and an insystem 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.
