CY7C109BN  
CY7C1009BN  
128K x 8 Static RAM  
Features  
Functional Description[1]  
• High speed  
The CY7C109BN/CY7C1009BN 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  
(CE1), an active HIGH Chip Enable (CE2), an active LOW  
Output Enable (OE), and three-state drivers. Writing to the  
device is accomplished 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).  
— tAA = 12 ns  
• Low active power  
— 495 mW (max. 12 ns)  
• Low CMOS standby power  
— 55 mW (max.) 4 mW  
• 2.0V Data Retention  
• Automatic power-down when deselected  
• TTL-compatible inputs and outputs  
• Easy memory expansion with CE1, CE2, and OE options  
Reading from the device is accomplished by taking Chip  
Enable 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  
specified by the address pins will appear on the I/O pins.  
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).  
The CY7C109BN is available in standard 400-mil-wide SOJ  
and 32-pin TSOP type I packages. The CY7C1009BN is  
available in a 300-mil-wide SOJ package. The CY7C1009BN  
and CY7C109BN are functionally equivalent in all other  
respects.
