6521
The Teridian 71M6521DE/FE is a highly integrated SoC with an MPU core, RTC, FLASH and LCD driver. Teridian's patented Single Converter Technology® with a 22-bit delta-sigma ADC, four (4) analog inputs, digital temperature compensation, precision voltage reference, battery voltage monitor, and 32-bit computation engine (CE) supports a wide range of residential 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. The IC supports 2-wire, 3-wire and 4-wire single-phase and dual-phase residential metering along with tamper-detection mechanisms.Features
