PRELIMINARY  
CY7C1049D  
4-Mbit (512K x 8) Static RAM  
Features  
Functional Description[1]  
• Pin- and function-compatible with CY7C1049B  
• High speed  
The CY7C1049D is a high-performance CMOS static RAM  
organized as 524,288 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.  
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 A18).  
— tAA = 10 ns  
• Low active power  
— ICC = 80 mA @ 10 ns (Commercial)  
— ICC = 90 mA @ 10 ns (Industrial)  
• 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.  
• 2.0V Data Retention  
• Automatic power-down when deselected  
• TTL-compatible inputs and outputs  
• Easy memory expansion with CE and OE features  
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).  
• Available in Lead-Free 36-Lead (400-Mil) Molded SOJ  
V36 package  
The CY7C1049D is available in a standard 400-mil-wide  
36-pin SOJ package with center power and ground (revolu-  
tionary) pinout.
