DESCRIPTION
The M27V405 is a low voltage 4 Mbit EPROM of-
fered in the OTP range (one time programmable).
It is ideally suited for microprocessor systems re-
quiring large data or program storage and is orga-
nised as 524,288 by 8 bits.
The M27V405 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.
