9. PROGRAM ERASURE (
m
PD75P3036KK-T ONLY)
The
m
PD75P3036KK-T is capable of erasing (FFH) the data written in a program memory and rewriting.
To erase the programmed data, expose the erasure window to light having a wavelength shorter than about 400 nm.
Normally, irradiate ultraviolet rays of 254-nm wavelength. The amount of exposure required to completely erase the
programmed data is as follows:
UV intensity x erasure time : 15 W s/cm
2
or more
Erasure time : 15 to 20 minutes (when a UV lamp of 12000
m
W/cm
2
is used. However, a longer time may be
needed because of deterioration in performance of the UV lamp, soiled erasure window, etc.)
When erasing the contents of data, set up the UV lamp within 2.5 cm from the erasure window. Further, if a filter is provided
for a UV lamp, irrradiate the ultraviolet rays after removing the filter.
10. OPAQUE FILM ON ERASURE WINDOW (
m
PD75P3036KK-T ONLY)
To protect from unintentional erasure by rays other than that of the lamp for erasing EPROM contents, and to protect
internal circuit other than EPROM from misoperating due to light radiation, cover the erasure window with an opaque film
when EPROM contents erasure is not performed.
11. ONE-TIME PROM SCREENING
Due to its structure, the one-time PROM versions (
m
PD75P3036GC-3B9,
m
PD75P3036GK-BE9) cannot be fully tested
before shipment by NEC. Therefore, NEC recommends that after the required data is written and the PROM is stored
under the temperature and time conditions shown below, the PROM should be verified via a screening.
