CY7C1021  
64K x 16 Static RAM  
(BLE) is LOW, then data from I/O pins (I/O1 through I/O8), is  
written into the location specified on the address pins (A0  
through A15). If Byte High Enable (BHE) is LOW, then data  
from I/O pins (I/O9 through I/O16) is written into the location  
specified on the address pins (A0 through A15).  
Features  
• High speed  
— tAA = 12 ns  
• CMOS for optimum speed/power  
• Low active power  
Reading from the device is accomplished by taking Chip En-  
able (CE) and Output Enable (OE) LOW while forcing the write  
enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then  
data from the memory location specified by the address pins  
will appear on I/O1 to I/O8. If Byte High Enable (BHE) is LOW,  
then data from memory will appear on I/O9 to I/O16. See the  
truth table at the back of this data sheet for a complete descrip-  
tion of read and write modes.  
— 1320 mW (max.)  
• Automatic power-down when deselected  
• Independent Control of Upper and Lower bits  
• Available in 44-pin TSOP II and 400-mil SOJ  
Functional Description  
The input/output pins (I/O1 through I/O16) are placed in a  
high-impedance state when the device is deselected (CE  
HIGH), the outputs are disabled (OE HIGH), the BHE and BLE  
are disabled (BHE, BLE HIGH), or during a write operation (CE  
LOW, and WE LOW).  
The CY7C1021 is a high-performance CMOS static RAM or-  
ganized as 65,536 words by 16 bits. This device has an auto-  
matic power-down feature that significantly reduces power  
consumption when deselected.  
Writing to the device is accomplished by taking Chip Enable  
(CE) and Write Enable (WE) inputs LOW. If Byte Low Enable  
The CY7C1021 is available in standard 44-pin TSOP Type II  
and 400-mil-wide SOJ packages.
