CY7C1034DV33 6-Mbit (256K X 24) Static RAM Features Functional Description High speed tAA = 10 ns Low active power ICC = 175 mA at f = 100 MHz The CY7C1034DV33 is a high performance CMOS static RAM organized as 256K words by 24 bits. This device has an automatic power-down feature that significantly reduces power consumption when deselected. Low CMOS standby power ISB2 = 25 mA To write to the device, enable the chip (CE1 LOW, CE2 HIGH, and CE3 LOW) while forcing the Write Enable (WE) input LOW. To read from the device, enable the chip by taking CE1 LOW, CE2 HIGH, and CE3 LOW, while forcing the Output Enable (OE) LOW and the Write Enable (WE) HIGH. See the Truth Table on page 7 for a complete description of Read and Write modes. Operating voltages of 3.3 0.3 V 2.0 V data retention Automatic power-down when deselected Transistor-transistor logic (TTL) compatible inputs and outputs Easy memory expansion with CE1, CE2, and CE3 features Available in Pb-free standard 119-Ball PBGA The 24 IO pins (IO0 to IO23) are placed in a high impedance state when the device is deselected (CE1 HIGH, CE2 LOW, or CE3 HIGH) or when the output enable (OE) is HIGH during a write operation. (CE1 LOW, CE2 HIGH, CE3 LOW, and WE LOW).

Valid SRAM operation does not occur until the power supplies reach the minimum operating VDD (3.0 V). 100 s (tpower) after reaching the minimum operating VDD, normal SRAM operation begins including reduction in VDD to the data retention (VCCDR, 2.0 V) voltage. 5. Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5 V, and input pulse levels of 0 to 3.0V. Test conditions for the read cycle use output loading as shown in part a) of the AC Test Loads and Waveform [4], unless specified otherwise. 6. tPOWER gives the minimum amount of time that the power supply is at typical VCC values until the first memory access is performed. 7. tHZOE, tHZCE, tHZWE, tLZOE, tLZCE, and tLZWE are specified with a load capacitance of 5 pF as in part (b) of AC Test Loads and Waveform [4]. Transition is measured 200 mV from steady state voltage. 8. These parameters are guaranteed by design and are not tested.

Data Retention Waveform DATA RETENTION MODE VCC 3.0V tCDR VDR > 2V 3.0V tR CE Notes 9. The internal write time of the memory is defined by the overlap of CE1 LOW, CE2 HIGH, CE3 LOW, and WE LOW. Chip enables must be active and WE must be LOW to initiate a write and the transition of any of these signals terminates the write. The input data setup and hold timing are 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. 11. Tested initially and after any design or process changes that may affect these parameters. 12. Full device operation requires linear VCC ramp from VDR to VCC(min) > 50 s or stable at VCC(min) > 50 s.
