General Description
The Teridian 71M6513 is a highly integrated SOC with an MCU core, RTC, FLASH and LCD driver. Teridian's Single Converter Technology™ with a 21bit 2nd order delta-sigma ADC, 6 analog inputs, digital temperature compensation, precision voltage reference and 32 bit computation engine support a wide range of polyphase metering applications with very few low cost external com-ponents. A 32kHz crystal timebase for the entire system and internal battery backup support for RAM and RTC further reduce system cost.
