CY7C1021DV33  
PRELIMINARY  
1-Mbit (64K x 16) Static RAM  
Writing to the device is accomplished by taking Chip Enable  
(CE) and Write Enable (WE) inputs LOW. If Byte Low Enable  
(BLE) is LOW, then data from I/O pins (I/O0 through I/O7), 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/O8 through I/O15) is written into the location  
specified on the address pins (A0 through A15).  
Features  
• Pin- and function-compatible with CY7C1021CV33  
• High speed  
— tAA = 8 ns  
• CMOS for optimum speed/power  
• Low active power  
Reading from the device is accomplished by taking Chip  
Enable (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/O0 to I/O7. If Byte High Enable (BHE) is  
LOW, then data from memory will appear on I/O8 to I/O15. See  
the truth table at the end of this data sheet for a complete  
description of Read and Write modes.  
— ICC = 75 mA @ 8 ns  
• Low CMOS standby power  
— ISB2 = 3 mA  
• Data retention at 2.0V  
• Automatic power-down when deselected  
• Independent control of upper and lower bits  
The input/output pins (I/O0 through I/O15) 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).  
• Available in 44-pin TSOP II, 400-mil SOJ, 48-ball FBGA  
Pb-Free Packages  
Functional Description[1]  
The CY7C1021DV33 is available in standard 44-pin TSOP  
Type II 400-mil-wide SOJ packages, as well as a 48-ball FBGA  
Pb-Free packages.  
The CY7C1021DV33 is a high-performance CMOS static  
RAM organized as 65,536 words by 16 bits. This device has  
an automatic power-down feature that significantly reduces  
power consumption when deselected.
