user manual of soliddigi 78m6613 power-measurement
DESCRIPTION
The 78M6613 is a highly integrated IC for simplified implementation of single-phase AC power measurement into power supplies, smart appliances, and other applications with embedded AC load monitoring and control. It is packaged in a small, 5mm x 5mm, 32-pin QFN package for optimal space savings.At the measurement interface, the device provides four analog inputs for interfacing to voltage and current sensors. Voltages from the sensors are fed to our Single Converter Technology® that uses a 22-bit delta-sigma ADC, independent 32-bit compute engine (CE), digital temperature compensation, and precision voltage references to provide better than 0.5% power measurement accuracy over a wide 2000:1 dynamic range.The integrated MPU core and 32KB of flash memory provides a flexible means of configuration, post-processing, data formatting, and interfacing to any host processor through the UART interface and/or DIO pins. Complete application firmware is available from Maxim and can be preloaded into the IC during manufacturing test. Alternatively, a complete array of ICE, development tools, and programming libraries are available to allow customization for each application.TRANSCRIPT

78M6613 User Manuel
78M6613 is the single-phase energy measurement chip designed by MAXIM. It has 22 bits built-in
delta-sigma ADC, 32 bits calculate engine, 8 bits 80515 kernel MPU, and can be widely used in
single-phase ammeter.
According to 78M6613, we manufacture the single-phase energy meter based on Arduino. You can use
PC serial communications software to communicate with this board and received its data by Arduino and
display it on LCD. 78m6613 has high voltage. Pay attention to it during operations. Arduino part,
onbard Uart to USB part are separated from 78M6613, therefore, they will not have high voltage. We
reserved the Wifi shield Io of Arduino. You can use Wifi shield at the same time which can enlarge the
scope of use.

This board uses LCM of 1602. LCD data ports D4-D7 are connected to IO D7-D4 on Arduino. The RS
port is connected to A5 on Arduino and is enable the port A4. Data received by serial can be directly
displayed on LCM through Arduino library. 78M6613 can use CLI mode, receiving serial commands, to
adjust internal information and data output method and etc. Default mode is output voltage, current,
power factor and fact periodically. As the connection way to 78m6613 of Arduino and FT232 is serial as
the same, we suggest unplug the sending pin P5 of FT232 when use Arduino. Similarly, when use USB
serial, unplug serial sending pins P9 and P10 of Arduino.
Note: The output data format of 78m6613 is : voltage value（mV）, current value（mA）, power value
（mW）, power factor, frequency（0.01Hz）.
