CY7C1049DV33 4-Mbit (512 K × 8) Static RAM 4-Mbit (512 K × 8) Static RAM Features Functional Description ■ Pin and function compatible with CY7C1049CV33 The CY7C1049DV33 is a high performance CMOS Static RAM organized as 512K words by 8-bits. Easy memory expansion is provided by an Active LOW Chip Enable (CE), an Active LOW Output Enable (OE), and tri-state drivers. You can write to the device by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. Data on the eight IO pins (IO0 through IO7) is then written into the location specified on the address pins (A0 through A18). ■ High speed ❐ tAA = 10 ns ■ Low active power ❐ ICC = 90 mA @ 10 ns (Industrial) ■ Low CMOS standby power ❐ ISB2 = 10 mA ■ 2.0 V data retention ■ Automatic power down when deselected ■ TTL compatible inputs and outputs ■ Easy memory expansion with CE and OE features ■ Available in Pb-free 36-pin (400 Mil) Molded SOJ and 44-pin TSOP II packages You can read from the device 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 appear on the IO pins. The eight input or output pins (IO0 through IO7) 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 CY7C1049DV33 is available in standard 400 Mil wide 36 -pin SOJ package and 44-pin TSOP II package with center power and ground (revolutionary) pinout.

Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5 V, input pulse levels of 0 to 3.0 V, and output loading of the specified IOL/IOH and 30 pF load capacitance. 8. tPOWER gives the minimum amount of time that the power supply must be at stable, typical VCC values until the first memory access is performed. 9. At any 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. tHZOE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in part (c) of Figure 1 on page 5. Transition is measured when the outputs enter a high impedance state. 11. 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 must be referred to the leading edge of the signal that terminates the write. 12. The minimum write cycle time for Write Cycle No. 2 (WE controlled, OE LOW) is the sum of tHZWE and tSD.
