CY7C1061BV33  
16-Mbit (1M x 16) Static RAM  
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 A19). 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 A19).  
Features  
• High speed  
— tAA = 10 ns  
• Low active power  
Reading from the device is accomplished by enabling the chip  
by taking CE LOW while forcing the Output Enable (OE) LOW  
and 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 back of this data sheet for a  
complete description of Read and Write modes.  
— 990 mW (max.)  
• Operating voltages of 3.3 ± 0.3V  
• 2.0V data retention  
• Automatic power-down when deselected  
• TTL-compatible inputs and outputs  
• Available in Pb-free and non Pb-free 54-pin TSOP II  
package  
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).  
Functional Description  
The CY7C1061BV33 is a high-performance CMOS Static  
RAM organized as 1,048,576 words by 16 bits.  
The CY7C1061BV33 is available in a 54-pin TSOP II package  
with center power and ground (revolutionary) pinout.  
Writing to the device is accomplished by enabling the chip (CE  
LOW) while forcing the Write Enable (WE) input LOW. If Byte
