Introduction
The 78M6618 PDU1 Firmware is a turnkey energy measurement solution optimized for use in single-phase AC Power Distribution Units (PDUs). At the sensor interface, the 78M6618 with PDU1 Firmware provides eight sense inputs for current and two sense inputs for voltage (single-phase). At the host interface, either a UART or SPI interface can be used to issue configure the device and access the following measurement data:

• RMS Voltage
• RMS Current (Line1, Line2,..Line8)
• Active Power (Line1, Line2,..Line8)
• Apparent Power (Line1, Line2,..Line8)
• Reactive Power (Line1, Line2,..Line8)
• Power Factor (Line1, Line2,..Line8)
• Energy (Line1, Line2,..Line8)
• Line Frequency

Fully functional demo code can be evaluated in an Evaluation Kit (EVK) and used as is in some applications. It can also serve as starting base for customization and adaptation to different system buses with an optional Software Development Kit (SDK).
