Instructions for Use:
Power Supply:
- Ensure that the supply voltage is within the specified range of 3.3V ± 10%.
- Use decoupling capacitors (typically 0.1μF and 10μF) close to the power pins to minimize noise.
Configuration:
- The device supports In-System Programming (ISP) and JTAG configuration modes.
- Use the appropriate configuration software (e.g., Lattice ispVM System) to program the device.
- Ensure that the configuration data is correctly formatted and compatible with the device.
Input/Output Handling:
- The I/O pins can tolerate voltages between 2.0V and 3.6V.
- Use pull-up or pull-down resistors as needed to ensure stable logic levels.
- Avoid driving the I/O pins beyond the specified voltage range to prevent damage.
Clocking:
- The device does not have an on-chip PLL. External clock sources should be used.
- Ensure that the clock signal is clean and stable to avoid timing issues.
Temperature Considerations:
- Operate the device within the industrial temperature range of -40°C to +85°C.
- Store the device in a temperature-controlled environment to prevent damage.
Mounting:
- Use a surface mount technique suitable for the LQFP package.
- Ensure proper soldering and alignment to avoid mechanical stress and short circuits.
RoHS Compliance:
- The device is RoHS compliant, ensuring it meets environmental standards for restricted substances.
Testing:
- Use boundary scan (JTAG) for testing and debugging.
- Verify the functionality of the device using test vectors and diagnostic tools.
For detailed programming and application notes, refer to the Lattice Semiconductor documentation and datasheets.
