CY7C1046CV33  
1M x 4 Static RAM  
Writing to the device is accomplished by taking Chip Enable  
(CE) and Write Enable (WE) inputs LOW. Data on the four I/O  
pins (I/O0 through I/O3) is then written into the location  
specified on the address pins (A0 through A19).  
Features  
• High speed  
— tAA = 10ns  
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 active power for 10 ns speed  
— 324 mW (max.)  
• 2.0V data retention  
• Automatic power-down when deselected  
• TTL-compatible inputs and outputs  
• Easy memory expansion with CE and OE features  
The four input/output pins (I/O0 through I/O3) 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 CY7C1046CV33 is available in a standard 400-mil-wide  
32-pin SOJ package with center power and ground (revolu-  
tionary) pinout.  
The CY7C1046CV33 is a high-performance CMOS static  
RAM organized as 1,048,576 words by 4 bits. Easy memory  
expansion is provided by an active LOW Chip Enable (CE), an  
active LOW Output Enable (OE), and three-state drivers.
