DESCRIPTION

The M27V201 is a low voltage 2 Mbit EPROM of-

fered in the two ranges UV (ultra violet erase) and

OTP (one time programmable). It is ideally suited

for microprocessor systems requiring large data or

program storage and is organised as 262,144 by 8

bits.

Figure 1. Logic Diagram

The M27V201 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 FDIP32W (window ceramic frit-seal package)

has a transparent lid which allow the user to ex-

pose the chip to ultraviolet light to erase the bit pat-

tern.
