The programming flow of the 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 4000Å. It should be noted that sun- lights and some types of fluorescent lamps have wavelengths in the range 3000-4000Å. 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/cm2 power rating. The ST62E20C should be placed within 2.5cm (1Inch) of the lamp tubes during erasure.
