NOTES:
26. This parameter is only sampled and is not 100% tested.
27. Typical values are for T
A
= 25°C and nominal supply voltages.
To clear all locations of their programmed contents, expose the window packaged device to
an ultra-violet light source. A dosage of 30 W second/cm
2
is required. This dosage can be
obtained with exposure to a wavelength of 2537 and intensity of 12000 μW/cm
2
for 40 to
45 minutes. The device should be about 1 inch from the source, and all filters should be
removed from the UV light source prior to erasure.
The PSD211R and similar devices will erase with light sources having wavelengths
shorter than 4000 . Although the erasure times will be much longer than with UV sources
at 2537 , exposure to fluorescent light and sunlight eventually erases the device. For
maximum system reliability, these sources should be avoided. If used in such an
environment, the package window should be covered by an opaque substance. Upon
delivery from WSI, or after each erasure, the PSD211R EPROM in the “1” or high state.
The configuration bits are in the “0” or low state. The code, configuration, and PAD MAP
data are loaded through the procedure of programming
Information for programming the device is available directly from WSI. Please contact your
local sales representative.
