Instructions for Use:

1. Power Supply:

   • Ensure that the supply voltage is within the specified range (4.5V to 5.5V).
   • Connect the VCC pin to the positive supply and GND pin to the ground.

2. Programming:

   • Use an ISP programmer or a UV erasable PROM programmer to program the device.
   • For ISP, connect the programming pins (M1, M2, PGM, and VPP) to the programmer.
   • For UV erasable PROM, expose the device to UV light for 15 minutes to erase the existing program before reprogramming.

3. I/O Configuration:

   • Configure the I/O pins as inputs or outputs according to your application requirements.
   • Ensure that the maximum current rating (±25mA) is not exceeded for any I/O pin.

4. Clock Signal:

   • Provide a clock signal to the device if your design requires it. The maximum clock frequency is 30MHz.

5. Temperature Considerations:

   • Operate the device within the specified temperature range (-40°C to +85°C) to ensure reliable performance.
   • Store the device in a temperature-controlled environment within the storage temperature range (-65°C to +150°C).

6. Handling:

   • Handle the device with care to avoid damage from static electricity.
   • Follow proper handling procedures to prevent damage to the pins and the package.

7. Testing:

   • After programming, test the device to ensure it functions correctly.
   • Verify the logic levels and timing parameters to confirm proper operation.

8. Documentation:

   • Refer to the datasheet and application notes for detailed information on specific features and advanced configurations.
