GENERAL DESCRIPTION
The Teridian 71M6521DE/FE is a highly integrated system-on-chip (SoC)
with an MPU core, RTC, 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 com-
ponents. 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.

is
provided
by
multiple
UARTs,
I
2C,
MICROWIRE, up to 18 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.
