MoBL® CY62148EV30 4-Mbit (512K x 8) Static RAM Features Functional Description The CY62148EV30[2] is a high performance CMOS static RAM organized as 512K words by 8 bits. This device features advanced circuit design to provide ultra low active current. This is ideal for providing More Battery Life™ (MoBL®) in portable applications such as cellular telephones. The device also has an automatic power down feature that significantly reduces power consumption. Placing the device into standby mode reduces power consumption by more than 99 percent when deselected (CE HIGH). The eight input and output pins (IO0 through IO7) 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). ■ Very high speed: 45 ns ❐ Wide voltage range: 2.20V to 3.60V ■ Temperature ranges ❐ Industrial: –40°C to +85°C ❐ Automotive-A: –40°C to +85°C ■ Pin compatible with CY62148DV30 ■ Ultra low standby power ❐ Typical standby current: 1 μA ❐ Maximum standby current: 7 μA (Industrial) ■ Ultra low active power ❐ Typical active current: 2 mA at f = 1 MHz ■ Easy memory expansion with CE, and OE features ■ Automatic power down when deselected ■ CMOS for optimum speed and power ■ Available in Pb-free 36-ball VFBGA, 32-pin TSOP II and 32-pin SOIC [1] packages To write to the device, take Chip Enable (CE) and Write Enable (WE) inputs LOW. Data on the eight IO pins (IO0 through IO7) 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 Write Enable (WE) HIGH. Under these conditions, the contents of the memory location specified by the address pins appear on the IO pins.

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 μs ramp time from 0 to VCC(min) and 200 μs wait time after VCC stabilization. 8. Under DC conditions the device meets a VIL of 0.8V (for VCC range of 2.7V to 3.6V) and 0.6V (for VCC range of 2.2V to 2.7V). However, in dynamic conditions Input LOW voltage applied to the device must not be higher than 0.6V and 0.4V for the above ranges. This is applicable to SOIC package only. Please refer to AN13470 for details. 9. Only chip enable (CE) must be HIGH at CMOS level to meet the ISB2 / ICCDR spec. Other inputs can be left floating.

Test Conditions for all parameters other than tri-state parameters assume signal transition time of 3 ns or less (1 V/ns), 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 Loads and Waveforms” on page 4. 13. 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. 14. tHZOE, tHZCE, and tHZWE transitions are measured when the output enter a high impedance state. 15. The internal write time of the memory is defined by the overlap of WE, CE = 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.
