1 Introduction
This application note provides hardware and system design guidelines for those incorporating the
78M6613 System on Chip in their products. These guidelines will help hardware engineers to reduce
design cycle times.
The following topics are discussed:
• Non-isolated Configuration
o Safety Precautions
o 3.3 VDC Supply (V3P3) and System Connections
o Line Voltage Resistor Divider Selection
o Shunt Selection and Connections
• Isolated Configuration
o Current Transformers
o Other Connections
o Voltage Transformers
• Calibration Considerations
• Basic Configuration
o Reset Circuitry
o In Circuit Emulator (ICE) Pins
o Connecting 5 V Devices
o Driving External Loads
o Connecting I2C EEPROMs
o Connecting 3-Wire EEPROMs
o UART0 (TX/RX)
o Power Supply Topologies
• Timing Reference
o Oscillator Connections and Components Selection
o PCB Layout Recommendations
o Other Considerations
A Hardware Design Checklist is provided at the end of this document as a quick summary.
