MAXIM INTEGRATED PRODUCTS 71M6511-IGT/F 芯片, 特殊功能
The is a single phase energy meter IC in 64 pin LQFP package. The 71M6511 is a highly integrated SOC with an MPU core, RTC, flash and LCD driver. Our Single Converter Technology with a 22bit delta-sigma ADC, three analogue inputs, digital temperature compensation, precision voltage reference and 32bit 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, I2C, a power 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.
