CY7C1046DV33  
4-Mbit (1 M × 4) Static RAM  
4-Mbit (1  
M × 4) Static RAM  
Features  
Functional Description  
Pin- and function-compatible with CY7C1046CV33  
The CY7C1046DV33[1] is a high-performance CMOS static  
RAM organized as 1M words by 4 bits. Easy memory  
expansion is provided by an active LOW Chip Enable (CE), an  
active LOW Output Enable (OE), and tri-state drivers. 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).  
High speed  
tAA = 10 ns  
Low active power  
ICC = 90 mA @ 10 ns  
Low CMOS standby power  
ISB2 = 10 mA  
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.  
2.0 V data retention  
Automatic power-down when deselected  
TTL-compatible inputs and outputs  
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).  
Easy memory expansion with CE and OE features  
Available in lead-free 400-mil-wide 32-pin SOJ package  
The CY7C1046DV33 is available in a standard 400-mil-wide  
32-pin SOJ package with center power and ground  
(revolutionary) pinout.
