71M6521DE/71M6521FE
Energy Meter IC
DATA SHEET
JANUARY 2008
GENERAL DESCRIPTION
The TERIDIAN 71M6521DE/FE is a highly integrated SOC with an MPU
core, RTC, FLASH and LCD driver. TERIDIAN’s patented Single Converter
Technologywith 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 re-
sidential metering applications with very few low-cost external components.
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.
Maximum design flexibility is provided by multiple UARTs, I2C, μWire, 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 stan-
dards.
