78M6613 HPL Firmware Quick Start Guide UG_6613_115

4 Rev.0

1 Introduction

The 78M6613 HPL Firmware is a turnkey energy measurement solution optimized for use in AC

high-power load units (HPLs), also known as “split-phase”. At the sensor interface, the 78M6613 with

HPL Firmware supports two voltage sense inputs and two current sense inputs. At the host interface,

ready-to-use data is available over a low baud-rate serial interface for minimal cost of data isolation.

Other key attributes of the HPL solution for the 78M6613 include:

• Accumulation intervals based on number of AC-cycles with a minimum of 4 AC cycles for real-time

feedback (15 Hz refresh rate).

• The firmware provides simple methods for calibration, alarm monitoring, and access to the following

measurement data over a low baud rate serial UART interface.

o Voltage Rms (Line1, Line2)

o Current Rms (Line1, Line2)

o Active Power (Line1, Line2, aggregate)

o Apparent Power (Line1, Line2, aggregate)

o Reactive Power (Line1, Line2, aggregate)

o Power Factor (Line1, Line2)

o Energy (Line 1, Line 2)

o Line Frequency

• Low-latency alarms for SAG and AC dropout detection.

• In addition, the firmware supports two distinctive hardware modes configurable at run-time: fixed

reference and floating reference.

Fully functional demo code can be evaluated in an Evaluation Kit (EVK) and used as is in most

applications. It can also serve as starting base for customization and adaptation to different needs with an

optional Software Development Kit (SDK).

This document overviews the steps for

• Getting Started with the EVK

• Getting Started with the SDK

• Getting Started with Flash Programming
