CY7C1021D  
1-Mbit (64K x 16) Static RAM  
Features  
Functional Description [1]  
• Pin-and function-compatible with CY7C1021B  
• High speed  
The CY7C1021D 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. The input/output pins  
(IO0 through IO15) are placed in a high-impedance state when:  
— tAA = 10 ns  
• Low active power  
— ICC = 80 mA @ 10 ns  
• Deselected (CE HIGH)  
• Outputs are disabled (OE HIGH)  
• Low CMOS Standby Power  
— ISB2 = 3 mA  
• BHE and BLE are disabled (BHE, BLE HIGH)  
• When the write operation is active (CE LOW, and WE LOW)  
• 2.0V Data Retention  
Write to the device by taking Chip Enable (CE) and Write  
Enable (WE) inputs LOW. If Byte Low Enable (BLE) is LOW,  
then data from IO pins (IO0 through IO7), is written into the  
location specified on the address pins (A0 through A15). If Byte  
High Enable (BHE) is LOW, then data from IO pins (IO8  
through IO15) is written into the location specified on the  
address pins (A0 through A15).  
• Automatic power-down when deselected  
• CMOS for optimum speed/power  
• Independent control of upper and lower bits  
• Available in Pb-free 44-pin 400-Mil wide Molded SOJ and  
44-pin TSOP II packages  
Read from the device 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 appears on IO0 to IO7.  
If Byte High Enable (BHE) is LOW, then data from memory  
appears on IO8 to IO15. See the “Truth Table” on page 8 for a  
complete description of read and write modes.
