The access time is 70ns (tAVQV) over the commercial

temperature range (0°C to +70°C) and VCC supply

voltage range of 4.75V-5.25V. At lower VCC voltages,

the access times are 80ns (4.5V-5.5V), 100ns (3.0V-

3.6V) and 120ns (2.7V-3.6V).

The Automatic Power Savings (APS) feature

substantially reduces active current when the device

is in static mode (addresses not switching). In APS

mode, the typical ICCR current is 1 mA at 5V VCC.

When either BE0# or BE1L#, BE1H# and RP# pins are

at VCC, the ICC CMOS standby mode is enabled.

When the RP# pin is at GND, deep power-down

mode is enabled which minimizes power

consumption and provides write protection during

reset. A reset time (tPHQV) is required from RP#

switching high until outputs are valid. Likewise, the

device has a wake time (tPHEL) from RP#-high until

writes to the CUI are recognized. With RP# at GND,

the WSM is reset and the status register is cleared.

The device is available in 56-Lead TSOP (Thin Small

Outline Package, 1.2 mm thick). Pinout is shown in

Figure 2.
