The 71M6521BE is a highly integrated SoC with an MPU core, flash, and LCD driver. Teridian's Single Converter Technology® with a 22-bit, delta-sigma ADC; four 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 further reduces system cost. The IC supports 2-wire single-phase residential metering along with tamper-detection mechanisms.
Maximum design flexibility is provided by multiple UARTs, I²C, MICROWIRE™, up to 14 DIO pins, and in-system programmable flash memory, which can be updated with data or application code in operation.
A complete array of ICE and development tools, programming libraries, and reference designs enable rapid development and certification of AMR and prepay meters that comply with worldwide electricity metering standards.
