DESCRIPTION  
The M27C256B is a 256 Kbit EPROM offered in  
the two ranges UV (ultra violet erase) and OTP  
(one time programmable). It is ideally suited for mi-  
croprocessor systems and is organized as 32,768  
by 8 bits.

TSOP28 (N)  
8 x 13.4 mm  
Figure 1. Logic Diagram  
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.  
For applications where the content is programmed  
only one time and erasure is not required, the  
M27C256B is offered in PDIP28, PLCC32 and  
TSOP28 (8 x 13.4 mm) packages.
