Description
19-5360; Rev 3; 9/11 71M6513/71M6513H A Maxim Integrated Products Brand 3-Phase Energy Meter IC DATA SHEET SEPTEMBER 2011 GENERAL .
The 71M6513 is a highly integrated system-on-chip SoC with an MPU core, real-time clock (RTC), flash, and LCD driver.
Features
* Wh Accuracy < 0.1% Over 2,000:1 Current Range
* Exceeds IEC 62053/ANSIC 12.20
* Voltage Reference
< 10ppm/°C (71M6513H) < 40ppm/°C (71M6513)
* Six Sensor Inputs
* VDD Referenced
* Auxiliary Analog Input for Neutral Current
* Low Jitter Wh/VARh Pulse Outputs
* Puls
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 powerfail comparator, a 5V LCD charge pump, up to 22 DIO pin
