GENERAL DESCRIPTION
The Teridian 71M6531D/F and 71M6532D/F are highly inte-
grated 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 com-
pensation, 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 bat-
tery 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 sin-
gle-ended voltage inputs.

Maximum design flexibility is provided by multiple UARTs, I C,
μWire, up to 21 DIO pins and in-system
programmable FLASH
memory, which can be updated with data or application code in
operation.
