DESCRIPTION  
The M27V401 is a low voltage 4 Mbit EPROM of-  
fered in the two range 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 524,288 by 8  
bits.

Figure 1. Logic Diagram  
The M27V401 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. A new pattern can then be written to the  
device by following the programming procedure.
