GENERAL DESCRIPTION
The TERIDIAN 71M6521BE is a highly integrated SOC with an MPU core,
FLASH and LCD driver. TERIDIAN’s patented Single Converter Technol-
ogy™ 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 32kHz crystal
time-base for the entire system further reduces system cost. The IC
supports 2-wire single-phase residential metering along with tamper-
detection mechanisms.
Maximum design flexibility is provided by multiple UARTs, I2C, μWire, up to
14 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 AMR and
Prepay meters that comply with worldwide electricity metering standards.
