UV Erasable Devices
One-Time-Programmable (OTP) Devices
Flash Devices
EEPROM Devices
The UV erasable version of EPROM program memory devices is optimal for prototype develop-
ment and pilot programs.
These devices can be erased and reprogrammed to any of the configuration modes. Third party
programmers are also available; refer to Microchip’s Third Party Guide (DS00104) for a list of
sources.
The amount of time required to completely erase a UV erasable device depends on: the wave-
length of the light, its intensity, distance from UV source, the process technology of the device
(how small are the memory cells).
The availability of OTP devices is especially useful for customers expecting code changes and
updates.
OTP devices, packaged in plastic packages, permit the user to program them once. In addition
to the program and data EPROM memories, the configuration bits must be programmed.
A Flash device allows its memory to be changed by an electric charge. This means that the sys-
tem can be designed so that programming may be performed in-circuit. Since no window is
required, the lower cost plastic packages can used for these devices.
An EEPROM device allows its memory to be erased by an electric charge. This means that the
system can be designed so that erasure and reprogramming may be performed in-circuit. Since
no window is required, the lower cost plastic packages can used for these devices.
Note:
Fluorescent lights and sunlight both emit ultraviolet light at the erasure wavelength.
Leaving a UV erasable device’s window uncovered could cause, over time, the
devices memory cells to become erased. The erasure time for a fluorescent light is
about three years, while sunlight requires only about one week. To prevent the mem-
ory cells from losing data, an opaque label should be placed over the erasure win-
dow.
