Additional Notes

The M2716 requires exposure to ultraviolet light for erasure, typically achieved using a UV EPROM eraser. The recommended erasure time is 15-20 minutes under a UV wavelength of 253.7 nm. After erasure, all bits return to a logical "1" state. For programming, a dedicated EPROM programmer is required, adhering to the specified voltage and timing requirements to ensure proper data retention and device longevity.
