CY62147EV30 MoBL(R)
4-Mbit (256K x 16) Static RAM
Features

Very high speed: 45 ns Temperature ranges Industrial: -40C to +85C Automotive-A: -40C to +85C Automotive-E: -40C to +125C Wide voltage range: 2.20V to 3.60V Pin compatible with CY62147DV30 Ultra low standby power Typical standby current: 1 A Maximum standby current: 7 A (Industrial) Ultra low active power Typical active current: 2 mA at f = 1 MHz Easy memory expansion with CE [1] and OE features Automatic power down when deselected CMOS for optimum speed and power Available in Pb-free 48-ball VFBGA (single/dual CE option) and 44-pin TSOPII packages Byte power down feature
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 when addresses are not toggling. Placing the device into standby mode reduces power consumption by more than 99% when deselected (CE HIGH or both BLE and BHE are HIGH). The input and output pins (IO0 through IO15) are placed in a high impedance state when:

Deselected (CE HIGH) Outputs are disabled (OE HIGH) Both Byte High Enable and Byte Low Enable are disabled (BHE, BLE HIGH) Write operation is active (CE LOW and WE LOW)

To write to the device, take Chip Enable (CE) and Write Enable (WE) inputs LOW. If Byte Low Enable (BLE) is LOW, then data from IO pins (IO0 through IO7) is written into the location specified on the address pins (A0 through A17). If Byte High Enable (BHE) is LOW, then data from IO pins (IO8 through IO15) is written into the location specified on the address pins (A0 through A17). To read from the device, take Chip Enable (CE) 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. For best practice recommendations, refer to the Cypress application note AN1064, SRAM System Guidelines.

Notes 5. VIL(min) = -2.0V for pulse durations less than 20 ns. 6. VIH(max) = VCC + 0.75V for pulse durations less than 20 ns. 7. Full device AC operation assumes a minimum of 100 s ramp time from 0 to VCC(min) and 200 s wait time after VCC stabilization. 8. Only chip enable (CE) and byte enables (BHE and BLE) need to be tied to CMOS levels to meet the ISB2 / ICCDR spec. Other inputs can be left floating. 9. Tested initially and after any design or process changes that may affect these parameters.

Notes 12. Test conditions for all parameters other than tri-state parameters assume signal transition time of 3 ns (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/IOH as shown in the AC Test Load and Waveforms on page 4. 13. AC timing parameters are subject to byte enable signals (BHE or BLE) not switching when chip is disabled. See application note AN13842 for further clarification. 14. At any 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 device. 15. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedance state. 16. The internal write time of the memory is defined by the overlap of WE, CE = VIL, BHE, BLE, or both = VIL. 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 must be referenced to the edge of the signal that terminates the write.
