Cypress’s state-of-the-art RadStop technology is radiation hardened through proprietary design and process hardening techniques. The 4-Mbit fast asynchronous SRAM with RadStop technology is also QML V certified with Defense Logistics Agency Land and Maritime (DLAM). To write to the device, take 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). To read from the device, take Chip Enable (CE) and Output Enable (OE) LOW while forcing the Write Enable (WE) HIGH. Under these conditions, the contents of the memory location specified by the address pins appear on the I/O pins. See the Truth Table on page 11 for a complete description of read and write modes. The eight input or 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 CYRS1049DV33 is available in a ceramic 36-pin Flatpackage with center power and ground (revolutionary) pinout. Easy memory expansion is provided by utilizing OE, CE, and tri-state drivers. For best practice recommendations, refer to the Cypress application note AN1064, SRAM System Guidelines.

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. 6. tPOWER gives the minimum amount of time that the power supply should be at typical VCC values until the first memory access is performed. 7. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, tHZBE is less than tLZBE, and tHZWE is less than tLZWE for any given device. 8. tHZOE, tHZCE, tHZBE, and tHZWE are specified with a load capacitance of 5 pF as in part (c) of Figure 2 on page 5. Transition is measured when the outputs enter a high impedance state. 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 setup 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. 4 (WE controlled, OE LOW) is the sum of tHZWE and tSD.
