Description
71M6511/71M6511H Single-Phase Energy Meter IC GENERAL .
The 71M6511 is a highly integrated SOC with an MPU core, RTC, flash, and LCD driver.
Features
* APRIL 2016
* Wh accuracy < 0.1% over 2000:1
range
* Exceeds IEC 62053/ANSIC 12.20
* Voltage reference
< 10ppm/C
* 71M6511H,
< 50ppm/°C
* 71M6511
* Three sensor inputs - VDD referenced
* Low jitter Wh/VARh pulse outputs
* Pulse count for pulse outputs
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 pi
