CY62126DV30 MoBL(R) 1-Mbit (64K x 16) Static RAM Features advanced circuit design to provide ultra-low active current. This is 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 by 90% when addresses are not toggling. The device can be put into standby mode reducing power consumption by more than 99% when deselected (CE HIGH). The input/output pins (I/O0 through I/O15) 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) or during a write operation (CE LOW and WE LOW). * Very high speed -- 55 ns * Temperature Ranges -- Industrial: -40C to 85C -- Automotive: -40C to 125C * Wide voltage range -- 2.2V - 3.6V * Pin compatible with CY62126BV * Ultra-low active power -- Typical active current: 0.85 mA @ f = 1 MHz -- Typical active current: 5 mA @ f = fMax (55 ns speed) * Ultra-low standby power * Easy memory expansion with CE and OE features * Automatic power-down when deselected * Available in Pb-free and non Pb-free 48-ball VFBGA and 44-pin TSOP Type II packages Functional Description[1] The CY62126DV30 is a high-performance CMOS static RAM organized as 64K words by 16 bits. This device features Writing to the device is accomplished by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. If Byte Low Enable (BLE) is LOW, then data from I/O pins (I/O0 through I/O7), is written into the location specified on the address pins (A0 through A15). If Byte High Enable (BHE) is LOW, then data from I/O pins (I/O8 through I/O15) is written into the location specified on the address pins (A0 through A15). Reading from the device is accomplished by taking 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 will appear on I/O0 to I/O7. If Byte High Enable (BHE) is LOW, then data from memory will appear on I/O8 to I/O15. See the truth table at the back of this data sheet for a complete description of read and write modes.

At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZBE is less than tLZBE, tHZOE is less than tLZOE. 12. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high-impedance state. 13. The internal Write time of the memory is defined by the overlap of WE, CE = VIL, BHE and/or BLE = 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 set-up and hold timing should be referenced to the edge of the signal that terminates the write.
