Instructions for Use:
- Power Supply: Ensure the supply voltage (Vcc) is set to 5V. Avoid exceeding this voltage to prevent damage.
- Programming: Apply 12.5V to the Vpp pin during programming operations. Follow the specific programming algorithm recommended for 27C4000 series EPROMs.
- Erase Cycle: To erase data, expose the device window to ultraviolet light for approximately 20 minutes. Ensure the UV wavelength is within the effective range for erasure.
- Handling Precautions: Handle with care to avoid static discharge. Use appropriate ESD protection measures.
- Storage and Handling: Store in a cool, dry place when not in use. Protect from excessive humidity and direct sunlight.
- Installation: Ensure proper orientation of the device during installation into the circuit board. Verify pin connections are correct to avoid shorts or misconnections.
