CY7C235A  
1K x 8 Registered PROM  
• Direct replacement for bipolar PROMs  
Features  
• Capable of withstanding greater than 2001V static dis-  
charge  
• CMOS for optimum speed/power  
• High speed  
Functional Description  
— 18 ns address set-up  
— 12 ns clock to output  
The CY7C235A is a high-performance 1024 word by 8 bit elec-  
trically programmable read only memory packaged in a slim  
300-mil plastic or hermetic DIP, 28-pin leadless chip carrier, or  
28-pin plastic leaded chip carrier. The memory cells utilize  
proven EPROM floating gate technology and byte-wide intelli-  
gent programming algorithms.  
• Low power  
— 495 mW (commercial)  
— 660 mW (military)  
• Synchronous and asynchronous output enables  
• On-chip edge-triggered registers  
• Programmable asynchronous registers (INIT)  
• EPROM technology, 100% programmable  
The CY7C235A replaces bipolar devices pin for pin and offers  
the advantages of lower power, superior performance, and  
high 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 the  
product will meet AC specification limits after customer pro-  
gramming.
