(INCLUDING
SCOPE AND JIG
CAPACITANCE)
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 PSD4XX 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 windows should be covered by an opaque substance.
Upon delivery from WSI, or after each erasure, the PSD4XX device has all bits in the PAD
and 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.
