9.6 EPROM Erasing
MC68HC705C8A — Rev. 3
MOTOROLA
The erased state of an EPROM or OTPROM byte is $00. EPROM
devices can be erased by exposure to a high intensity ultraviolet (UV)
light with a wave length of 2537 Å. The recommended erasure dosage
(UV intensity on a given surface area x exposure time) is 15 Ws/cm
lamps should be used without short-wave filters, and the EPROM device
should be positioned about one inch from the UV source.
OTPROM devices are shipped in an erased state. Once programmed,
they cannot be erased. Electrical erasing procedures cannot be
performed on either EPROM or OTPROM devices.
