3.2 PROGRAMMING MODES

3.2.1 Program Memory

EPROM/OTP programming mode is set by a

+12.5V voltage applied to the TEST/VPP pin. The

programming flow of the ST62T08C,T09C,T10C,

T20C and E20C is described in the User Manual of

the EPROM Programming Board.

Table 5. ST6220C Program Memory Map

Note: OTP/EPROM devices can be programmed

with

the

development

tools

available

from

STMicroelectronics (please refer to Section 12 on

page 99).

3.2.2 EPROM Erasing

The EPROM devices can be erased by exposure

to Ultra Violet light. The characteristics of the MCU

are such that erasure begins when the memory is

exposed to light with a wave lengths shorter than

approximately 4000Å. It should be noted that sun-

light and some types of fluorescent lamps have

wavelengths in the range 3000-4000Å.

It is thus recommended that the window of the

MCU 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 is exposure

to short wave ultraviolet light which have a wave-

length 2537Å. The integrated dose (i.e. U.V. inten-

sity x exposure time) for erasure should be a mini-

mum of 30W-sec/cm2. The erasure time with this

dosage is approximately 30 to 40 minutes using an

ultraviolet lamp with 12000µW/cm2 power rating.

The EPROM device should be placed within

2.5cm (1inch) of the lamp tubes during erasure.
