DESCRIPTION
The M27V512 is a low voltage 512 Kbit EPROM
offered in the two ranges UV (ultra viloet erase)
and OTP (one time programmable). It is ideally
suited for microprocessor systems and is orga-
nized as 65,536 by 8 bits.
The M27V512 operates in the read mode with a
supply voltage as low as 3V. The decrease in op-
erating power allows either a reduction of the size
of the battery or an increase in the time between
battery recharges.
The FDIP28W (window ceramic frit-seal package)
has transparent lid which allows 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
M27V512 is offered in PDIP28, PLCC32 and
TSOP28 (8 x 13.4 mm) packages.
