CY7C109D  
CY7C1009D  
PRELIMINARY  
1-Mbit (128K x 8) Static RAM  
memory expansion is provided by an active LOW Chip Enable  
(CE1), an active HIGH Chip Enable (CE2), an active LOW  
Output Enable (OE), and tri-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).  
Features  
• Pin- and function-compatible with  
CY7C109B/CY7C1009B  
• High speed  
— tAA = 10 ns  
• Low active power  
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.  
— ICC = 60 mA @ 10 ns  
• Low CMOS standby power  
— ISB2 = 1.2 mA (‘L’ Version only)  
• 2.0V Data Retention  
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).  
• Automatic power-down when deselected  
• TTL-compatible inputs and outputs  
• Easy memory expansion with CE1, CE2, and OE options  
• Available in Pb-Free Packages  
The CY7C109D is available in standard 400-mil-wide SOJ and  
32-pin TSOP type I packages. The CY7C1009D is available in  
a 300-mil-wide SOJ Pb-Free package. The CY7C1009D and  
CY7C109D are functionally equivalent in all other respects.  
Functional Description[1]  
The CY7C109D/CY7C1009D is a high-performance CMOS  
static RAM organized as 131,072 words by 8 bits. Easy
