DESCRIPTION
The M27C800 is an 8 Mbit EPROM offered in the
two ranges UV (ultra violet erase) and OTP (one
time programmable). It is ideally suited for microprocessor systems requiring large data or program
storage. It is organised as either 1 Mwords of 8 bit
or 512 Kwords of 16 bit. The pin-out is compatible
with the most common 8 Mbit Mask ROM.
The FDIP42W (window ceramic frit-seal package)
has a transparent lid which allows the user to expose the chip to ultraviolet light to erase the bit pattern.
A new pattern can then be written rapidly to the device by following the programming procedure.
For applications where the content is programmed
only one time and erasure is not required, the
M27C800 is offered in PDIP42, PLCC44 and
SO44 packages.
