CY7C1049V33  
512K x 8 Static RAM  
sion is provided by an active LOW Chip Enable (CE), an active  
LOW Output Enable (OE), and three-state drivers. Writing to  
the device is accomplished by taking Chip Enable (CE) and  
Features  
• High speed  
Write Enable (WE) inputs LOW. Data on the eight I/O pins (I/O

through I/O ) is then written into the location specified on the  
7
• Low active power  
address pins (A through A ).

— 504 mW (max.)  
Reading from the device is accomplished by taking Chip  
Enable (CE) and Output Enable (OE) LOW while forcing Write  
Enable (WE) HIGH. Under these conditions, the contents of  
the memory location specified by the address pins will appear  
on the I/O pins.  
• Low CMOS standby power (Commercial L version)  
— 1.8 mW (max.)  
• 2.0V Data Retention (660 W at 2.0V retention)  
• Automatic power-down when deselected  
• TTL-compatible inputs and outputs  
µ
The eight input/output pins (I/O through I/O ) are placed in a

high-impedance state when the device is deselected (CE  
HIGH), the outputs are disabled (OE HIGH), or during a write  
operation (CE LOW, and WE LOW).  
• Easy memory expansion with CE and OE features  
Functional Description  
The CY7C1049V33 is available in a standard 400-mil-wide  
36-pin SOJ package with center power and ground (revolution-  
ary) pinout.  
The CY7C1049V33 is a high-performance CMOS Static RAM  
organized as 524,288 words by 8 bits. Easy memory expan-
