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.
