Reprogrammable PROM  
low-power stand-by mode. The CY7C271 is packaged in the  
300-mil slim package. The CY7C274 is packaged in the  
industry standard 600-mil package. Both the CY7C271 and  
CY7C274 are available in a cerDIP package equipped with an  
erasure window to provide for reprogrammability. When  
exposed to UV light, the PROM is erased and can be repro-  
grammed. The memory cells utilize proven EPROM floating  
gate technology and byte-wide intelligent programming  
algorithms.  
Features  
• CMOS for optimum speed/power  
• Windowed for reprogrammability  
• High speed  
— 30 ns (Commercial)  
— 35 ns (Military)  
• Low power  
The CY7C271 and CY7C274 offer the advantage of lower  
power, superior performance, and programming yield. The  
EPROM cell requires only 12.5V for the super voltage, and low  
current requirements allow for gang programming. The  
EPROM cells allow each memory location to be tested 100%  
because 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)  
— 715 mW (military)  
• Super low standby power  
— Less than 165 mW when deselected  
• EPROM technology 100% programmable  
• Slim 300-mil package (7C271)  
• Direct replacement for bipolar PROMs  
• Capable of withstanding >2001V static discharge  
Reading the 7C271 is accomplished by placing active LOW  
signals on CS1 and CE, and an active HIGH on CS2. Reading the  
7C274 is accomplished by placing active LOW signals on OE and  
CE. The contents of the memory location addressed by the address  
lines (A0A14) will become available on the output lines (O0O7).  
Functional Description  
The CY7C271 and CY7C274 are high-performance  
32,768-word by 8-bit CMOS PROMs. When disabled (CE  
HIGH), the 7C271/7C274 automatically powers down into a
