DESCRIPTION
The M27C4001 is a 4 Mbit EPROM offered in the
two ranges UV (ultra violet erase) and OTP (one
time programmable). It is ideally suited for micro-
processor systems requiring large programs and
is organised as 524,288 by 8 bits.
The FDIP32W (window ceramic frit-seal package)
and LCCC32W (leadless chip carrier package)
have a transparent lid which allow the user to ex-
pose the chip to ultraviolet light to erase the bit pat-
tern. A new pattern can then be written to the
device by following the programming procedure.
For applications where the content is programmed
only one time and erasure is not required, the
M27C4001 is offered in PDIP32, PLCC32 and
TSOP32 (8 x 20 mm) packages.
