DESCRIPTION
The M27C1001 is a 1 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 programs and
is organized as 131,072 words of 8 bits. The FDIP32W (window ceramic
frit-seal package) and the LCCC32W (leadless chip carrier package)
have a transparent lids which allow the user to expose the chip to
ultraviolet light to erase the bit pattern. 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 M27C1001 is offered in PDIP32, PLCC32 and TSOP32
(8 x 20 mm) packages.
