Functional Description

The CY62126EV30 is a high performance CMOS static RAM

organized as 64K words by 16 bits[1]. 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 when addresses are not toggling. Placing the

device in standby mode reduces power consumption by more

than 99 percent when deselected (CE HIGH). The input and

output pins (IO0through 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 (IO0through IO7) is written into the location

specified on the address pins (A0through A15). If Byte High

Enable (BHE) is LOW, then data from IO pins (IO8through IO15)

is written into the location specified on the address pins (A0

through A15).

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 IO0to IO7. If

Byte High Enable (BHE) is LOW, then data from memory

appears on IO8to IO15. See the “Truth Table” on page 9 for a

complete description of read and write modes.

Note

1. For best practice recommendations, refer to the Cypress application note AN1064, SRAM System Guidelines.

Notes

4. VIL(min) = –2.0V for pulse durations less than 20 ns.

5. VIH(max) = VCC+0.75V for pulse durations less than 20 ns.

6. Full device AC operation assumes a 100 μs ramp time from 0 to Vcc(min) and 200 μs wait time after Vcc stabilization.

7. 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.

Notes

10. Test conditions assume signal transition time of 3 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 and 30-pF load capacitance.

11. 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.

12. 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.

13. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedance state.

14. 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 refer to the edge of signal that terminates write.
