| CY7C1049CV33 4-Mbit (512K x 8) Static RAM Features * Temperature Ranges -- Commercial: 0C to 70C -- Industrial: -40C to 85C -- Automotive: -40C to 125C * High speed -- tAA = 10 ns * Low active power -- 324 mW (max.) * 2.0V data retention * Automatic power-down when deselected * TTL-compatible inputs and outputs * Easy memory expansion with CE and OE features Functional Description[1] The CY7C1049CV33 is a high-performance CMOS Static RAM organized as 524,288 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 A18). 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 CY7C1049CV33 is available in standard 400-mil-wide 36-pin SOJ package and 44-pin TSOP II package with center power and ground (revolutionary) pinout.

Max. Min. -20 Max. Unit Notes: 6. 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. 7. 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. 8. tHZOE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in part (d) of AC Test Loads. Transition is measured 500 mV from steady-state voltage. 9. 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. 10. 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. 11. The minimum Write cycle time for Write Cycle No. 3 (WE controlled, OE LOW) is the sum of tHZWE and tSD.
