CY62148CV25/30/33 MoBLTM
512K x 8 MoBL Static RAM
Features
* High Speed -- 55 ns and 70 ns availability * Low voltage range: -- CY62148CV25: 2.2V-2.7V -- CY62148CV30: 2.7V-3.3V -- CY62148CV33: 3.0V-3.6V * Pin compatible with CY62148V * Ultra low active power -- Typical active current: 1.5 mA @ f = 1MHz * * * * -- Typical active current: 5.5 mA @ f = fmax (70 ns speed) Low standby power Easy memory expansion with CE and OE features Automatic power-down when deselected CMOS for optimum speed/power advanced circuit design to provide ultra-low active current. This is ideal for providing More Battery LifeTM (MoBLTM) in portable applications such as cellular telephones. The device also has an automatic power-down feature that significantly reduces power consumption by 80% when addresses are not toggling. The device can be put into standby mode when deselected (CE HIGH). 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 CY62148CV25/30/33 are available in a 36-ball FBGA package.

Notes: 7. Test conditions assume signal transition time of 5 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to VCC(typ.), and output loading of the specified IOL/IOH and 30 pF load capacitance. 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. tHZOE, tHZCE, and tHZWE are specified with CL = 5 pF as in part (b) of AC Test Loads. Transition is measured 200 mV from steady-state voltage. 10. The internal write time of the memory is defined by the overlap of CE LOW and WE LOW. Both signals must be LOW to initiate a write and either signal can terminate a write by going HIGH. The data input set-up and hold timing should be referenced to the rising edge of the signal that terminates the write. 11. The minimum write cycle time for Write Cycle #3 (WE controlled, OE LOW) is the sum of tHZWE and tSD.

Data I/O is high impedance if OE = VIH. 16. If CE goes HIGH simultaneously with WE HIGH, the output remains in a high-impedance state. 17. During this period, the I/Os are in output state and input signals should not be applied.
