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

9. These parameters are guaranteed by design and are not tested.
10. The internal Write time of the memory is defined by the overlap of CE LOW and WE LOW. Chip enables must be active and WE and byte enables must be LOW to
initiate a Write, and the transition of any of these signals can terminate the Write. The input data set-up and hold timing should be referenced to the leading edge
of the signal that terminates the Write.
11. The minimum Write cycle time for Write Cycle No. 3 (WE controlled, OE LOW) is the sum of t
