PRELIMINARY  
CY7C1049  
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 de-  
vice is accomplished by taking chip enable (CE) and write en-  
able (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 = 15 ns  
• Low active power  
— 1210 mW (max.)  
Reading from the device is accomplished by taking chip en-  
able (CE) and output enable (OE) LOW while forcing write en-  
able (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  
The CY7C1049 is available in a standard 400-mil-wide 36-pin  
SOJ package with center power and ground (revolutionary)  
pinout.  
The CY7C1049 is a high-performance CMOS static RAM or-  
ganized as 524,288 words by 8 bits. Easy memory expansion
