CY7C1061DV33
PRELIMINARY
16-Mbit (1M x 16) Static RAM
Features
Functional Description
• High speed
The CY7C1061DV33 is a high-performance CMOS Static
RAM organized as 1,048,576 words by 16 bits.
— tAA = 10 ns
Writing to the device is accomplished by enabling the chip
(CE1 LOW and CE2 HIGH) while forcing the Write Enable
(WE) input 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 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).
• Low active power
— ICC = 125 mA @ 10 ns
• Low CMOS standby power
— ISB2 = 25 mA
• Operating voltages of 3.3 ± 0.3V
• 2.0V data retention
• Automatic power-down when deselected
• TTL-compatible inputs and outputs
• Easy memory expansion with CE1 and CE2 features
• Available in Pb-free 54-pin TSOP II package and 48-ball
VFBGA packages
Reading from the device is accomplished by enabling the chip
by taking CE1 LOW and CE2 HIGH 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.
The input/output pins (I/O0 through I/O15) are placed in a
high-impedance state when the device is deselected (CE1
HIGH/CE2 LOW), the outputs are disabled (OE HIGH), the
BHE and BLE are disabled (BHE, BLE HIGH), or during a
Write operation (CE1 LOW, CE2 HIGH, and WE LOW).
The CY7C1061DV33 is available in a 54-pin TSOP II package
with center power and ground (revolutionary) pinout, and a
48-ball Very fine-pitch ball grid array (VFBGA) package

3. Tested initially and after any design or process changes that may affect these parameters.
4. Valid SRAM operation does not occur until the power supplies have reached the minimum operating VDD (3.0V). 100µs (tpower) after reaching the minimum
operating VDD, normal SRAM operation can begin including reduction in VDD to the data retention (VCCDR, 2.0V) voltage.

Notes:
5. Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V. Test conditions for the Read cycle use
output loading shown in part a) of the AC test loads, unless specified otherwise.
6. tPOWER gives the minimum amount of time that the power supply should be at typical VCC values until the first memory access can be performed.
7. tHZOE, tHZCE, tHZWE, tHZBE and tLZOE, tLZCE, t\LZWE, tLZBE are specified with a load capacitance of 5 pF as in (b) of AC Test Loads. Transition is measured ±200 mV from steady-state
voltage.
8. These parameters are guaranteed by design and are not tested.
9. The internal Write time of the memory is defined by the overlap of CE1 LOW (CE2 HIGH) 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.
10. The minimum Write cycle time for Write Cycle No. 3 (WE controlled, OE LOW) is the sum of tHZWE and tSD.
