GENERAL DESCRIPTION
The Teridian 71M6531D/F and 71M6532D/F are highly
integrated SOCs with an MPU core, RTC, FLASH and LCD
driver. Teridian’s patented 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 32-kHz 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, and 3-wire single-phase and
dual-phase residential metering along with tamper-detection
mechanisms. The 71M6531D/F offers single-ended inputs for
two current channels and two single-ended voltage inputs.
The 71M6532D/F has two differential current inputs and three
single-ended voltage inputs.
Maximum design flexibility is provided by multiple UARTs, I
2C,
μWire, up to 21 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 TOU, AMR and Prepay meters that comply with
worldwide electricity metering standards.
