CY7C245A  
2K x 8 Reprogrammable Registered PROM  
Functional Description  
Features  
• Windowed for reprogrammability  
• CMOS for optimum speed/power  
The CY7C245A is a high-performance, 2K x 8, electrically pro-  
grammable, read only memory packaged in a slim 300-mil  
plastic or hermetic DIP. The 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 utilize proven EPROM floating-gate technology  
and byte-wide intelligent programming algorithms.  
• High speed  
— 15-ns address set-up  
— 10-ns clock to output  
• Low power  
The CY7C245A replaces bipolar devices and offers the advan-  
tages of lower power, reprogrammability, superior perfor-  
mance and high programming yield. The EPROM cell requires  
only 12.5V for the supervoltage, and low current requirements  
allow gang programming. The EPROM cells allow each mem-  
ory location to be tested 100%, because each location is writ-  
ten into, erased, and repeatedly exercised prior to encapsula-  
tion. Each PROM is also tested for AC performance to  
guarantee that after customer programming the product will  
meet AC specification limits.  
— 330 mW (commercial) for -25 ns  
— 660 mW (military)  
• Programmable synchronous or asynchronous output  
enable  
• On-chip edge-triggered registers  
• Programmable asynchronous register (INIT)  
• EPROM technology, 100% programmable  
• Slim, 300-mil, 24-pin plastic or hermetic DIP  
• 5V ±10% VCC, commercial and military  
• TTL-compatible I/O  
The CY7C245A has an asynchronous initialize function (INIT).  
This function acts as a 2049th 8-bit word loaded into the on-chip  
register. It is user programmable with any desired word, or may be  
used as a PRESET or CLEAR function on the outputs. INIT is trig-  
gered by a low level, not an edge.  
• Direct replacement for bipolar PROMs  
• Capable of withstanding greater than 2001V static dis-  
charge
