CY62187EV30, MoBL(R)
64 Mbit (4M x 16) Static RAM
ideal for providing More Battery LifeTM (MoBL(R)) in portable applications such as cellular telephones. The device also has an automatic power down feature that significantly reduces power consumption by 99 percent when addresses are not toggling. The device can also be put into standby mode when deselected (CE1 HIGH or CE2 LOW or both BHE and BLE are HIGH). The input and output pins (IO0 through IO15) are placed in a high impedance state when: deselected (CE1HIGH or CE2 LOW), outputs are disabled (OE HIGH), both Byte High Enable and Byte Low Enable are disabled (BHE, BLE HIGH), or during a write operation (CE1 LOW, CE2 HIGH and WE LOW). To write to the device, take Chip Enables (CE1 LOW and CE2 HIGH) and Write Enable (WE) input LOW. If Byte Low Enable (BLE) is LOW, then data from I/O pins (IO0 through IO7), is written into the location specified on the address pins (A0 through A21). If Byte High Enable (BHE) is LOW, then data from I/O pins (IO8 through IO15) is written into the location specified on the address pins (A0 through A21). To read from the device, take Chip Enables (CE1 LOW and CE2 HIGH) and Output Enable (OE) LOW while forcing the Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then data from the memory location specified by the address pins appear on IO0 to IO7. If Byte High Enable (BHE) is LOW, then data from memory appears on IO8 to IO15. See the Truth Table on page 9 for a complete description of read and write modes.

Notes 10. Test conditions for all parameters other than tri-state parameters assume signal transition time of 1V/ns, timing reference levels of VTH, input pulse levels of 0 to VCC(typ), and output loading of the specified IOL/IOH as shown in AC Test Loads on page 4. 11. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZBE is less than tLZBE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given device. 12. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedence state. 13. The internal Write time of the memory is defined by the overlap of WE, CE1 = VIL, BHE and/or BLE = VIL, and CE2 = VIH. All signals must be ACTIVE to initiate a write and any of these signals can terminate a write by going INACTIVE. The data input setup and hold timing should be referenced to the edge of the signal that terminates the write.

Notes 17. Data I/O is high impedance if OE = VIH. 18. If CE1 goes HIGH and CE2 goes LOW simultaneously with WE = VIH, the output remains in a high impedance state. 19. During this period the I/Os are in output state and input signals should not be applied.
