2 EPROM PROGRAM MEMORY

The program memory of the OTP and EPROM de-

vices can be programmed with EPROM program-

ming tools available from STMicroelectronics

EPROM Erasure

EPROM devices are erased by exposure to high

intensity UV light admitted through the transparent

window. This exposure discharges the floating

gate to its initial state through induced photo cur-

rent.

It is recommended that the EPROM devices be

kept out of direct sunlight, since the UV content of

sunlight can be sufficient to cause functional fail-

ure. Extended exposure to room level fluorescent

lighting may also cause erasure.

An opaque coating (paint, tape, label, etc...)

should be placed over the package window if the

product is to be operated under these lighting con-

ditions. Covering the window also reduces IDD in

power-saving modes due to photo-diode leakage

currents.
