049B  
CY7C1049B  
512K x 8 Static RAM  
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  
Write Enable (WE) inputs LOW. Data on the eight I/O pins (I/O0  
through I/O7) is then written into the location specified on the  
address pins (A0 through A18).  
Features  
• High speed  
— tAA = 12 ns  
• Low active power  
— 1320 mW (max.)  
Reading from the device is accomplished by taking Chip En-  
able (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)  
— 2.75 mW (max.)  
• 2.0V Data Retention (400 µW at 2.0V retention)  
• Automatic power-down when deselected  
• TTL-compatible inputs and outputs  
• Easy memory expansion with CE and OE features  
The eight input/output pins (I/O0 through I/O7) 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).  
Functional Description[1]  
The CY7C1049B is available in a standard 400-mil-wide  
36-pin SOJ package with center power and ground (revolu-  
tionary) pinout.  
The CY7C1049B is a high-performance CMOS static RAM or-  
ganized as 524,288 words by 8 bits. Easy memory expansion
