Lamps lose intensity as they age. The distance from lamp to unit should be maintained at 1 inch. This exposure discharges the floating gate to its initial state through induced photo current.
Program Inhibit Mode The program inhibit mode allows programming several MMES simultaneously with different data for each one by controlling which ones receive the program pulse. Full text of ” IC Datasheet: All bits will be at a “1” level output high in this initial state and after any full erasure.
Typical conditions are for operation at: An opaque coating paint, tape, label, etc. Programmers, components, and system designs have been erroneously suspected when incom- plete erasure was the basic problem. The transparent lid allows the user to expose the chip to ultraviolet light to erase the bit pattern. The UV content of sunlight may cause a partial erasure of some bits in a relatively short period of time.

It is recommended that the MME be kept out of direct sunlight. The table of “Electrical Characteristics” provides conditions for actual device operation. The MME is packaged in a pin dual-in-line package with transparent lid. MMES sprom be programmed in parallel with the same data in this mode.
All input voltage levels, including the program pulse on chip-enable are TTL compatible.

Search 27116 history of over billion web pages on the Internet. Table II shows the 3 programming modes. Any or all of the 8 bits associated with an address location may be programmed wFth a single epom pulse applied to the chip enable pin. A new pattern can then be written into the device by following the programming procedure.
Program Verify Mode The programming of the MME may be verified either 1 word at a time during the programming as shown in the timing diagram or by reading all of the words out at the end of the programming sequence.
Transition times S 20 ns unless noted otherwise.
In- complete erasure will cause symptoms that can be misleading. The erasure time is increased by the square of the distance if the distance is doubled the erasure time goes up by a factor of 4.
No pins should be left open. The programming sequence is: Extended expo- sure to room level fluorescent lighting will also cause erasure.
2716 – 2716 16K EPROM Datasheet
Any individual address, a sequence of addresses, or addresses chosen at random may be programmed. This is done 8 bits a byte at a time.
These are shown in Table I. The MME to be erased should be placed 1 inch away from the lamp and no filters should be used.
EPROM Technical Data
To prevent damage the device it must not be inserted into a board with power applied. An erasure system should be calibrated periodically.
All similar inputs of the MME may be par- alleled. Capacitance Fatasheet guaranteed by periodic testing. Except for “Operating Temperature Range” they are not meant to imply that the devices should be operated at these limits. After the address and data signals are stable the program pin is pulsed from VI L to VIH with a pulse width between 45 ms and 55 ms.
Direct sunlight any intense light can cause temporary functional fail- ure due to generation of photo current. When a lamp is changed, the distance is changed, or the lamp is aged, the eprkm should be checked to make certain full erasure is occurring.
