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
ST62T08C,T09C,T10C,T20C/E20C is described
in the User Manual of the EPROM Programming
Board.

Table 2. ST62T08C, T09C Program Memory Map
Table 3. ST62T10C Program Memory Map
Table 4. ST62T20C,E20C Program Memory Map
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 unintentional erasure 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 integrated dose (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 12000μW/cm
2
power rating. The
ST62E20C should be placed within 2.5cm (1Inch)
of the lamp tubes during erasure.
