DESCRIPTION
TheM27C256Bis a256KbitEPROMofferedin the
two ranges UV (ultra violet erase) and OTP (one
time programmable). It is ideally suited for micro-
processorsystems and is organizedas 32,768 by
8 bits.
The FDIP28W (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 to the
deviceby following the programming procedure.
Forapplicationswherethe content isprogrammed
only one time and erasure is not required, the
M27C256B is offered in PDIP32, PLCC32 and
TSOP28(8 x 13.4mm) packages.
