identical, but are packaged in 300-mil (7C291A, 7C293A) and  
600-mil wide plastic and hermetic DIP packages (7C292A).  
The CY7C293A has an automatic power down feature which  
reduces the power consumption by over 70% when deselect-  
ed. The 300-mil ceramic package may be equipped with an  
erasure window; when exposed to UV light the PROM is  
erased and can then be reprogrammed. The memory cells uti-  
lize proven EPROM floating-gate technology and byte-wide in-  
telligent programming algorithms.

CMOS for optimum speed/power

The CY7C291A, CY7C292A, and CY7C293A are plug-in re-  
placements for bipolar devices and offer the advantages of  
lower power, reprogrammability, superior performance and  
programming yield. The EPROM cell requires only 12.5V for  
the supervoltage and low current requirements allow for gang  
programming. The EPROM cells allow for each memory loca-  
tion to be tested 100%, as each location is written into, erased,  
and repeatedly exercised prior to encapsulation. Each PROM  
is also tested for AC performance to guarantee that after cus-  
tomer programming the product will meet DC and AC specifi-  
cation limits.
