Instructions for Use:

1. Power Supply:

   • Ensure that the VCC supply is stable at 3.3V ± 5%.
   • Connect the VCCIO pins to the appropriate voltage level (3.3V, 2.5V, or 1.8V) based on your application requirements.

2. Configuration:

   • The device can be configured using JTAG or SPI interfaces.
   • For in-system programming (ISP), ensure that the JTAG chain is properly configured and connected to the programming tool.

3. Input/Output Handling:

   • Configure the I/O banks to the desired voltage levels before applying signals.
   • Use pull-up or pull-down resistors as needed to ensure proper signal levels.

4. Temperature Considerations:

   • Operate the device within the specified temperature range (-40°C to +125°C) to ensure reliable performance.

5. ESD Protection:

   • Handle the device with care to avoid electrostatic discharge (ESD) damage.
   • Use ESD-protected workstations and tools when handling the device.

6. Mounting and Soldering:

   • Follow the recommended soldering profile for the TQG144 package to ensure proper attachment to the PCB.
   • Avoid excessive thermal stress during soldering.

7. Testing and Verification:

   • After programming and mounting, perform functional tests to verify the correct operation of the device.
   • Use boundary scan (JTAG) for testing and debugging if necessary.

8. Documentation:

   • Refer to the datasheet and user manual for detailed information on pinout, timing diagrams, and other technical specifications.
