GENERAL DESCRIPTION
FEATURES
The 71M6513 is a highly integrated system-on-chip SoC with an MPU core,
real-time clock (RTC), flash, and LCD driver. Our Single Converter . Wh Accuracy < 0.1% Over 2,000:1
Technology® with a 21-bit delta-sigma ADC, six analog inputs, digital tem-
perature compensation, precision voltage reference, and 32-bit computation
engine (CE) supports a wide range of poly-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 22 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.
