16-Mbit (1M x 16) Static RAM
Features
Functional Description
■
High speed
❐ tAA = 10 ns
The CY7C1061DV33 is a high performance CMOS Static RAM
organized as 1,048,576 words by 16 bits.
■
Low active power
❐ ICC = 175 mA at 10 ns
■
Low CMOS standby power
❐ ISB2 = 25 mA
■
Operating voltages of 3.3 ± 0.3V
To write to the device, take Chip Enables (CE1 LOW and CE2
HIGH) and Write Enable (WE) input 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 A19).
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 A19).
■
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 and 48-Ball VFBGA
packages
To read from the device, take Chip Enables (CE1 LOW and CE2
HIGH) 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 9
for a complete description of Read and Write modes.
The input or output pins (IO0 through IO15) 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 VFBGA package.

3. Valid SRAM operation does not occur until the power supplies have reached the minimum operating VDD (3.0V). 100 µs (tpower) after reaching the minimum operating
VDD, normal SRAM operation begins including reduction in VDD to the data retention (VCCDR, 2.0V) voltage.

Notes
4. Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, and input pulse levels of 0 to 3.0V. Test conditions for the read cycle use output
loading shown in part a) of AC Test Loads and Waveforms, unless specified otherwise.
5. tPOWER gives the minimum amount of time that the power supply is at typical VCC values until the first memory access is performed.
6. tHZOE, tHZCE, tHZWE, tHZBE , tLZOE, tLZCE, tLZWE, and tLZBE are specified with a load capacitance of 5 pF as in (b) of AC Test Loads and Waveforms. Transition is measured ±200 mV
from steady state voltage.
7. These parameters are guaranteed by design and are not tested.
8. The internal write time of the memory is defined by the overlap of WE, CE1 = VIL, and CE2 = VIH. 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 input data setup and hold timing should be referenced to the edge of the signal that
terminates the write.
9. The minimum write cycle time for Write Cycle No. 2 (WE controlled, OE LOW) is the sum of tHZWE and tSD.

15. CE is a shorthand combination of both CE1 and CE2 combined. It is active LOW.
16. Data IO is high impedance if OE, BHE, and/or BLE = VIH.
17. If CE goes HIGH simultaneously with WE going HIGH, the output remains in a high impedance state.
