CY7C291A  
CY7C292A/CY7C293A  
2K x 8 Reprogrammable PROM  
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.

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.

Notes:  
6. tHZCS2 and tACS2 refer to 7C293A CS1 only.  
These PROMs need to be within 1 inch of the lamp during  
erasure. Permanent damage may result if the PROM is ex-  
posed to high-intensity UV light for an extended period of time.  
Erasure Characteristics  
Wavelengths of light less than 4000 Angstroms begin to erase  
these PROMs. For this reason, an opaque label should be  
placed over the window if the PROM is exposed to sunlight or  
fluorescent lighting for extended periods of time.  
2
7258 Wsec/cm is the recommended maximum dosage.  
Programming Information  
The recommended dose of ultraviolet light for erasure is a  
wavelength of 2537 Angstroms for a minimum dose (UV inten-  
sity x exposure time) of 25 Wsec/cm2. For an ultraviolet lamp  
with a 12 mW/cm power rating, the exposure time would be  
approximately 35 minutes.  
Programming support is available from Cypress as well as  
from a number of third-party software vendors. For detailed  
programming information, including a listing of software pack-  
ages, please see the PROM Programming Information located  
at the end of this section. Programming algorithms can be ob-  
tained from any Cypress representative.
