DESCRIPTION

The M27V256 is a low voltage 256 Kbit EPROM

offered in the two ranges UV (ultra violet erase)

and OTP (one time programmable). It is ideally

suited for microprocessor systems and is orga-

nized as 32,768 by 8 bits.

Figure 1. Logic Diagram

The M27V256 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 a 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.
