CY7C1069AV33 2M x 8 Static RAM Features • High speed — tAA = 8, 10, 12 ns • Low active power — 1080 mW (max.) • 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 device is accomplished by enabling the chip (by taking CE1 LOW and CE2 HIGH) and Write Enable (WE) inputs LOW. Reading from the device is accomplished by enabling the chip (CE1 LOW and CE2 HIGH) as well as forcing the Output Enable (OE) LOW while forcing the Write Enable (WE) HIGH. 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/O7) 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 CY7C1069AV33 is available in a 54-pin TSOP II package with center power and ground (revolutionary) pinout, and a 48-ball fine-pitch ball grid array (FBGA) package.

Valid SRAM operation does not occur until the power supplies have reached the minimum operating VDD (3.0V). As soon as 1ms (Tpower) after reaching the minimum operating VDD , normal SRAM operation can begin including reduction in VDD to the data retention (VCCDR, 2.0V) voltage. 4. 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, and output loading of the specified IOL/IOH and transmission line loads. Test conditions for the Read cycle use output loading shown in part a) of the AC test loads, unless specified otherwise. 5. This part has a voltage regulator which steps down the voltage from 3V to 2V internally. tpower time has to be provided initially before a Read/Write operation is started. 6. tHZOE, tHZSCE, tHZWE and tLZOE, tLZCE, and tLZWE 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. 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 CE1 LOW / CE2 HIGH, and WE LOW. CE1 and WE must be LOW along with CE2 HIGH 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. 9. The minimum Write cycle time for Write Cycle No. 3 (WE controlled, OE LOW) is the sum of tHZWE and tSD.
