CY7C1069DV33
16-Mbit (2M x 8) Static RAM
Features
Functional Description
■
High speed
❐ tAA = 10 ns
The CY7C1069DV33 is a high performance CMOS Static RAM
organized as 2,097,152 words by 8 bits.
■
Low active power
❐ ICC = 175 mA at 10 ns
■
Low CMOS standby power
❐ ISB2 = 25 mA
To write to the device, take Chip Enables (CE1 LOW and CE2
HIGH) and Write Enable (WE) input LOW. Data on the eight IO
pins (IO0 through IO7) is then written into the location specified
on the address pins (A0 through A20).
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. Under these conditions, the contents of the
memory location specified by the address pins will appear on the
IO pins. See Truth Table on page 8 for a complete description of
Read and Write modes.
■
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 and 48-Ball VFBGA
packages
The input and output pins (IO0 through IO7) are placed in a high
impedance state when the device is deselected (CE1 HIGH or
CE2 LOW), the outputs are disabled (OE HIGH), or during a write
operation (CE1 LOW, CE2 HIGH, and WE LOW).
The CY7C1069DV33 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. 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, tLZOE, tLZCE, and tLZWE 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. CE1 and WE are LOW along with CE2 HIGH 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 = VIH.
17. If CE goes HIGH simultaneously with WE going HIGH, the output remains in a high impedance state.
