PROGRAMMING MODES
(Cont’d)
1.4.2 Program Memory
EPROM/OTP programming mode is set by a
+12.5V voltage applied to the TEST/V
PP
pin. The
programming flow of the ST62T15C,T25C/E25C is
described in the User Manual of the EPROM Pro-
gramming Board.
Table 2. ST62T15C Program Memory Map
Table 3. ST62T25C,E25C Program MemoryMap
Note
: OTP/EPROM devices can be programmed
with the development tools available from STMi-
croelectronics (ST62E2X-EPB or ST622X-KIT).
1.4.3 EPROM Erasing
The EPROM of the windowed package of the
MCUs may be erased by exposure to Ultra Violet
light. The erasure characteristic of the MCUs is
such that erasure begins when the memory is ex-
posed to light with a wave lengths shorter than ap-
proximately 4000. It should be noted that sun-
lights and some types of fluorescent lamps have
wavelengths in the range 3000-4000.
It is thus recommended that the window of the
MCUs packages be covered by an opaque label to
prevent unintentionalerasure problems when test-
ing the application in such an environment.
The recommended erasure procedure of the
MCUs EPROM is the exposure to short wave ul-
traviolet light which have a wave-length 2537A.
The integrateddose (i.e. U.V. intensity x exposure
time) for erasure should be a minimum of 30W-
sec/cm
2
. The erasure time with this dosage is ap-
proximately 30 to 40 minutes using an ultraviolet
lamp with
12000
μ
W/cm
2
ST62E25C should be placed within 2.5cm (1Inch)
of the lamp tubes during erasure.
