CY7C1049BV33  
512K x 8 Static RAM  
expansion is provided by an active LOW Chip Enable (CE), an  
active LOW Output Enable (OE), and three-state drivers. Writ-  
ing 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 = 15 ns  
• Low active power  
— 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 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 CY7C1049BV33 is available in a standard 400-mil-wide  
36-pin SOJ and 44-pin TSOPII packages with center power  
and ground (revolutionary) pinout.  
The CY7C1049BV33 is a high-performance CMOS Static  
RAM organized as 524,288 words by 8 bits. Easy memory
