71M6532D Energy Meter IC

description

The 71M6531D/F and 71M6532D/F are highly integrated SoC devices with MPU cores, RTCs, flash memory, LCD drivers. Teridian's Single Converter Technology 1 22-bit, Δ-ΣADC®; Four analog inputs, digital temperature compensation; precision voltage reference; battery voltage monitor; and a 32-bit compute engine (CE) to support a wide range of residential metering applications with very few low-cost external components.

A 32kHz crystal time for the entire system and internal battery backup RAM and RTC support further reduces system costs. The IC supports 2-, 3-, and 4-wire single-phase and dual-phase residential metering and tamper detection mechanisms. The 71M6531D/F provides two current channels and two single-ended voltage inputs as single-ended inputs. The 71M6532D/F has two differential current inputs and three single-ended voltage inputs.

Multiple UARTs provide maximum design flexibility, with I²C interface, MICROWIRE™, up to 21 DIO pins, and programmable flash memory within the system, which can run application code or data updates.

A complete range of ICE and development tools, programming libraries and reference designs enable the rapid development of local products, AMRs and certifications, and prepaid meters to meet global electricity metering standards.
