CY7C291A  
2K x 8 Reprogrammable PROM  
Features  
Functional Description  
• Windowed for reprogrammability  
• CMOS for optimum speed/power  
• High speed  
The CY7C291A is a high-performance 2K-word by 8-bit  
CMOS PROM. It is packaged in a 300-mil ceramic package  
which may be equipped with an erasure window; when  
exposed to UV light the PROM is erased and can then be  
reprogrammed. The memory cells utilize proven EPROM  
— 20 ns (Commercial)  
floating-gate  
programming algorithms.  
technology  
and  
byte-wide  
intelligent  
— 35 ns (Military)  
• Low power  
The CY7C291A is a plug-in replacement for bipolar devices  
and offers the advantage 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 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 perfor-  
mance to guarantee that after customer programming the  
product will meet DC and AC specification limits.  
— 660 mW (Commercial and Military)  
• Low standby power  
— 220 mW (Commercial and Military)  
• EPROM technology 100% programmable  
• Slim 300-mil or standard 600-mil packaging available  
5V ±10% VCC, commercial and military  
TTL-compatible I/O  
Direct replacement for bipolar PROMs  
Capable of withstanding >2001V static discharge  
A read is accomplished by placing an active LOW signal on  
CS1, and active HIGH signals on CS2 and CS3. The contents  
of the memory location addressed by the address line  
(A0A10) will become available on the output lines (O0O7).
