CY62128DV30 MoBL
1 Mb (128K x 8) Static RAM
Features
* * * * Very high speed: 55 and 70 ns Wide voltage range: 2.2V to 3.6V Pin compatible with CY62128V Ultra-low active power -- Typical active current: 0.85 mA @ f = 1 MHz -- Typical active current: 5 mA @ f = fMAX Ultra-low standby power Easy memory expansion with CE1, CE2, and OE features Automatic power-down when deselected Packages offered in a 32-lead SOIC, a 32-lead TSOP, a 32-lead Short TSOP, and a 32-lead Reverse TSOP power consumption by 90% when addresses are not toggling. The device can be put into standby mode reducing power consumption by more than 99% when deselected Chip Enable 1 (CE1) HIGH or Chip Enable 2 (CE2) LOW. The input/output pins (I/O0 through I/O7) are placed in a high-impedance state when: deselected Chip Enable 1 (CE1) HIGH or Chip Enable 2 (CE2) LOW, outputs are disabled (OE HIGH), or during a write operation (Chip Enable 1 (CE1) LOW and Chip Enable 2 (CE2) HIGH and Write Enable (WE) LOW). Writing to the device is accomplished by taking Chip Enable 1 (CE1) LOW with Chip Enable 2 (CE2) HIGH and Write Enable(WE) LOW. Data on the eight I/O pins is then written into the location specified on the Address pin (A0 thro. A16). Reading from the device is accomplished by taking Chip Enable 1 (CE1) LOW with Chip Enable 2 (CE2) HIGH 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 will appear on the I/O pins. The eight input/output pins (I/Oo through I/O7) are placed in a high-impedance state when the device is deselected (CE1 HIGH or CE2 LOW), the outputs are disabled (OE HIGH) or during a write operation (CE1 LOW, CE2 HIGH), and WE LOW).

Notes: 3. VIL(min.) = -2.0V for pulse durations less than 20 ns., VIH(max.) = Vcc+0.75V for pulse durations less than 20 ns. 4. Full device operation requires linear ramp of Vcc from 0V to Vcc(min) and Vcc must be stable at Vcc(min) for 500 s. 5. Typical values are included for reference only and are not guaranteed or tested. Typical values are measured at VCC = VCC(typ), TA = 25C. 6. Tested initially and after any design or proces changes that may affect these parameters.

Notes: 8. Test conditions assume signal transition time of 1V/ns or less, timing reference levels of VCC(typ.)/2, input pulse levels of 0 to VCC(typ.), and output loading of the specified IOL. 9. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZBE is less than tLZBE, tHZOE is less than t. 10. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high-impedance state. 11. The internal write time of the memory is defined by the overlap of WE, CE1 = VIL, and CE2 = VIH. All signals. 12. Device is continuously selected. OE, CE1 = VIL, CE2 = VIH. 13. WE is HIGH for Read cycle.
