CY7C1009  
128K x 8 Static RAM  
active HIGH chip enable (CE2), an active LOW output enable  
(OE), and three-state drivers. Writing to the device is accom-  
plished by taking chip enable one (CE1) and write enable (WE)  
inputs LOW and chip enable two (CE2) input HIGH. 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).  
Features  
• High speed  
— tAA = 10 ns  
• Low active power  
— 1017 mW (max., 12 ns)  
Reading from the device is accomplished by taking chip en-  
able one (CE1) and output enable (OE) LOW while forcing  
write enable (WE) and chip enable two (CE2) HIGH. Under  
these conditions, the contents of the memory location speci-  
fied by the address pins will appear on the I/O pins.  
• Low CMOS standby power  
— 55 mW (max.), 4 mW (Low power version)  
• 2.0V Data Retention (Low power version)  
• Automatic power-down when deselected  
• TTL-compatible inputs and outputs  
• Easy memory expansion with CE1, CE2, and OEoptions  
The eight input/output pins (I/O0 through I/O7) are placed in a  
high-impedance state when the device is deselected (CE1  
HIGH or CE2 LOW), the outputs are disabled (OE HIGH), or  
during a write operation (CE1 LOW, CE2 HIGH, and WE LOW).  
Functional Description  
The CY7C109 is available in standard 400-mil-wide SOJ and  
32-pin TSOP type I packages. The CY7C1009 is available in  
a 300-mil-wide SOJ package. The CY7C1009 and CY7C109  
are functionally equivalent in all other respects.  
The CY7C109 / CY7C1009 is a high-performance CMOS stat-  
ic RAM organized as 131,072 words by 8 bits. Easy memory  
expansion is provided by an active LOW chip enable (CE1), an
