MMES may 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. Full text of ” IC Dtasheet Search the history of over billion web pages on the Internet.
Programmers, components, and system designs have been erroneously suspected when incom- plete erasure was the basic problem.
Multiple pulses are not needed but will not cause device damage. The UV content of sunlight may cause a partial erasure of some bits in a relatively short period of time.
No pins should be left open. 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.
The distance from daasheet to unit should be maintained at 1 inch. Typical conditions are for operation at: All similar inputs of the MME may be par- alleled. Transition times S 20 ns unless noted otherwise. Capacitance Is guaranteed by periodic testing.

Extended expo- sure to room level fluorescent lighting will also cause erasure. Direct sunlight any intense light can cause temporary functional fail- ure due to generation of photo current.
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. 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.
A new pattern can then be written into the device by following the programming procedure. Lamps lose intensity as they age. The MME is epron in a pin dual-in-line package with transparent lid.

In- complete erasure will cause symptoms that can be misleading. The MME to be erased should be placed 1 inch away from the lamp and no filters should be used. The table of “Electrical Characteristics” provides conditions for actual device operation. Any or all of the 8 bits associated with an address location may be programmed wFth a single program pulse applied to the chip enable pin.
It is recommended that the MME be kept out of direct sunlight. All bits will be at a “1” level output high in this initial state and after any full erasure.
An opaque coating paint, tape, label, etc. This is done 8 bits a byte at a time. 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. This exposure discharges the floating gate to its initial state through induced photo current.
Except for “Operating Temperature Range” they are not meant to imply that the devices should be operated at these limits. Table II shows the 3 programming modes.
When a lamp is changed, the distance is changed, or the lamp is aged, the system should be checked to make certain full erasure is occurring.

The programming sequence is: To prevent damage the device eproj must not be inserted into a board with power applied. Any individual address, a sequence of addresses, or addresses chosen at random may be programmed. The transparent lid allows the user to expose the chip to ultraviolet light to erase the bit pattern.
An erasure system should be calibrated periodically. These are shown in Table I.
