Features  
Functional Description  
Pin- and function-compatible with CY7C1018CV33 and  
CY7C1019CV33  
The CY7C1018DV33/CY7C1019DV33 is a high-performance  
CMOS static RAM organized as 131,072 words by 8 bits. Easy  
memory expansion is provided by an active LOW Chip Enable  
(CE), an active LOW Output Enable (OE), and three-state  
drivers. This device has an automatic power-down feature that  
significantly reduces power consumption when deselected.  
High speed  
tAA = 10 ns  
Low Active Power  
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 A16).  
ICC = 60 mA @ 10 ns  
Low CMOS Standby Power  
ISB2 = 3 mA  
2.0 V Data retention  
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.  
Automatic power-down when deselected  
CMOS for optimum speed/power  
Center power/ground pinout  
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).  
Easy memory expansion with CE and OE options  
Available in Pb-free 32-pin 400-Mil wide Molded SOJ, 32-pin  
The CY7C1018DV33/CY7C1019DV33 are available in Pb-free  
32-pin 400-Mil wide Molded SOJ, 32-pin TSOP II and 48-ball  
VFBGA packages.
