78M6618 Datasheet | Maxim Integrated

DESCRIPTION FEATURES The Teridian 78M6618 is a highly integrated IC for 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 pute engine (CE), digital temperature pensation, and precision voltage references to provide better than 0.5% accuracy over a wide 2000:1 dynamic range. 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. plete firmware for mon applications is available from Teridian and can be loaded into the IC during manufacturing test. Alternatively, a plete array of ICE, development tools, and programming libraries are available to allow customization MPU code for each application. - < 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 pute Engine (CE) - 8-Bit MPU (80515), One Clock Cycle per Instruction with 4KB MPU XRAM - 128KB Flash with Security - Integrated ICE for MPU Debug - 32k Hz Time Base with Hardware Watchdog Timer - 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/Ro HS-pliant (6/6) 68-Pin QFN -...
