Instructions for Use:
- Power Supply: Ensure the power supply voltage is within the specified range of 4.5V to 5.5V.
- Installation: Install the 27C4002 in a suitable socket or directly on the PCB, ensuring correct orientation and secure placement.
- Programming:
- The device can be programmed using standard EPROM programmers compatible with the 27C4002.
- After programming, protect the window from light to prevent accidental erasure.
- Erasing: To erase data, expose the chip to ultraviolet light through the transparent window for approximately 20 minutes.
- Handling: Handle with care to avoid static damage; use anti-static precautions.
- Storage: Store in an anti-static bag when not in use to prevent damage.
- Temperature Considerations: Operate within the temperature range of 0°C to 70°C to ensure reliable performance.
