| CY7C1010DV33 2-Mbit (256K x 8)Static RAM Features * Pin and function compatible with CY7C1010CV33 * High speed -- tAA = 10 ns * Low active power -- ICC = 90 mA @ 10 ns * Low CMOS standby power * * * * * -- ISB2 = 10 mA 2.0V data retention Automatic power-down when deselected TTL-compatible inputs and outputs Easy memory expansion with CE and OE features Available in Lead-Free 44-pin TSOP II package Functional Description[1] The CY7C1010DV33 is a high-performance CMOS Static RAM organized as 256K words by 8 bits. Easy memory expansion is provided by an active LOW Chip Enable (CE), an active LOW Output Enable (OE), and three-state drivers. Writing to the device is accomplished by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. Data on the eight I/O pins (I/O0 through I/O7) is then written into the location specified on the address pins (A0 through A17). Reading from the device is accomplished by taking Chip Enable (CE) and Output Enable (OE) LOW while forcing Write Enable (WE) HIGH. Under these conditions, the contents of the memory location specified by the address pins will appear on the I/O pins. The eight input/output pins (I/O0 through I/O7) are placed in a high-impedance state when the device is deselected (CE HIGH), the outputs are disabled (OE HIGH), or during a Write operation (CE LOW, and WE LOW). The CY7C1010DV33 is available in standard 44-pin TSOP II package with center power and ground (revolutionary) pinout.

AC characteristics (except High-Z) are tested using the load conditions shown in Figure (a). High-Z characteristics are tested for all speeds using the test load shown in Figure (c). 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. 6. tPOWER gives the minimum amount of time that the power supply should be at stable, typical VCC values until the first memory access can be performed. 7. tHZOE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in part (d) of AC Test Loads. Transition is measured when the outputs enter a high impedance state. 8. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given device. 9. The internal Write time of the memory is defined by the overlap of CE LOW, and WE LOW. CE and WE must be LOW to initiate a Write, and the transition of either 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.
