DESCRIPTION  
The M27V402 is a low voltage, low power 4 Mbit  
UV erasable and electrically programmable  
EPROM, ideally suited for handheld and portable  
microprocessor systems requiring large programs.  
It is organized as 262,144 by 16 bits.

Figure 1. Logic Diagram  
The M27V402 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 FDIP40W (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.
