CY7C261  
CY7C263/CY7C264  
8K x 8 Power-Switched and Reprogrammable PROM  
the CY7C261 automatically powers down into a low-power  
standby mode. It is packaged in a 300-mil-wide package. The  
Features  
• CMOS for optimum speed/power  
• Windowed for reprogrammability  
• High speed  
CY7C263 and CY7C264 are packaged in 300-mil-wide and  
600-mil-wide packages respectively, and do not power down  
when deselected. The reprogrammable packages are  
equipped with an erasure window; when exposed to UV light,  
these PROMs are erased and can then be reprogrammed.  
The memory cells utilize proven EPROM floating-gate  
technology and byte-wide intelligent programming algorithms.  
— 20 ns (Commercial)  
— 25 ns (Military)  
• Low power  
The CY7C261, CY7C263, and CY7C264 are plug-in replace-  
ments for bipolar devices and offer the advantages of lower  
power, 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 location 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 customer  
programming the product will meet DC and AC specification  
limits.  
— 660 mW (Commercial)  
— 770 mW (Military)  
• Super low standby power (7C261)  
— Less than 220 mW when deselected  
— Fast access: 20 ns  
• EPROM technology 100% programmable  
• Slim 300-mil or standard 600-mil packaging available  
• 5V ± 10% VCC, commercial and military  
• Capable of withstanding greater than 2001V static  
discharge  
• TTL-compatible I/O  
• Direct replacement for bipolar PROMs  
Read is accomplished by placing an active LOW signal on CS.  
The contents of the memory location addressed by the  
address line (A0−A12) will become available on the output lines  
(O0−O7).  
Functional Description  
The CY7C261, CY7C263, and CY7C264 are high-perfor-  
mance 8192-word by 8-bit CMOS PROMs. When deselected,
