DESCRIPTION

FEATURES

The Teridian 78M6618 is

a highly integrated IC for

 < 0.5% Wh Accuracy Over Wide 2000:1

Current Range and Over Temperature

 Exceeds IEC 62053/ANSI C12.20 Standards

 Voltage Reference < 40ppm/°C

 10 Sensor Inputs—V3P3 Referenced

 21-Bit Delta-Sigma ADC with Independent

32-Bit Compute Engine (CE)

independent monitoring and measurement of up to eight

single-phase AC outlets. With multiple host interface options,

an integrated LCD driver, and configurable I/Os, the device is

ideal for metered power distribution units (PDUs) and rack

enclosures for the data center, as well as intelligent power

strips and subpanels in the grid-friendly digital home.

At the measurement interface, the device provides 10 analog

inputs for interfacing to voltage and current sensors. Scaled

voltages from the sensors are fed to our Single Converter

Technology^®that uses a 21-bit delta-sigma ADC, independent

32-bit compute engine (CE), digital temperature compensation,

and precision voltage references to provide better than 0.5%

accuracy over a wide 2000:1 dynamic range.

 8-Bit MPU (80515), One Clock Cycle per

Instruction with 4KB MPU XRAM

 128KB Flash with Security

 Integrated ICE for MPU Debug

 32kHz Time Base with Hardware Watchdog

Timer

The integrated MPU core and 128KB of flash memory provides

a flexible means of configuration, postprocessing, data

formatting, interfacing to host processor through a UART or

SPI™ interface, displaying output data to an LCD, or using

DIO pins for intelligent relay control. Complete firmware for

common applications is available from Teridian and can be

loaded into the IC during manufacturing test. Alternatively, a

complete array of ICE, development tools, and programming

libraries are available to allow customization MPU code for

each application.

 UART and High-Speed Slave SPI Host Interface

Options

 Up to 19 General-Purpose 5V Tolerant I/O Pins

 LCD Driver (Up to 70 Pixels)

 Packaged in a Lead(Pb)-Free/RoHS-Compliant

(6/6) 68-Pin QFN

 Robust Sub-Metering Application Firmware:

o True RMS Calculations for Current, Voltage,

Line Frequency, Real Power, Reactive

Power, Apparent Power, and Power Factor

o Accumulated Watt-Hours, Kilowatt-Hours,

and Cost

o Intelligent Switch Control at Zero Crossings

o Digital Temperature Compensation

o Phase Compensation (15)

o Quick Calibration Routines

o 46-64Hz Line Frequency Range with Same

Calibration

o Programmable Alarm Thresholds

o High-Level UART Communication Protocols

o High-Level SPI Communication Protocols
