SUMMARY DESCRIPTION
The M27W512 is a low voltage 512 Kbit EPROM
offered in the two range UV (ultra violet erase) and
OTP (one time programmable). It is ideally suited
for microprocessor systems and is organized as
65536 by 8 bits.
The M27W512 operates in the read mode with a
supply voltage as low as 2.7V at –40 to 85°C tem-
perature range. The decrease in operating power
allows either a reduction of the size of the battery
or an increase in the time between battery re-
charges.
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
M27W512 is offered in PDIP28, PLCC32 and
TSOP28 (8 x 13.4 mm) packages.
In addition to the standard versions, the packages
are also available in Lead-free versions, in compli-
ance with JEDEC Std J-STD-020B, the ST ECO-
PACK 7191395 Specification, and the RoHS
(Restriction of Hazardous Substances) directive.
