ULTRA LOW POWER CMOS STATIC RAM

FEATURES

DESCRIPTION

The ISSI IS62WV2568ALL / IS62WV2568BLL are high-

speed, 2M bit static RAMs organized as 256K words by 8

bits. It is fabricated using ISSI's high-performance CMOS

technology. This highly reliable process coupled with

innovative circuit design techniques, yields high-

performance and low power consumption devices.

• High-speed access time: 55ns, 70ns

• CMOS low power operation

– 36 mW (typical) operating

– 9 µW (typical) CMOS standby

• TTL compatible interface levels

• Single power supply

When CS1 is HIGH (deselected) or when CS2 is LOW

(deselected)orwhenCS1isLOW,CS2isHIGH,thedevice

assumes a standby mode at which the power dissipation

can be reduced down with CMOS input levels.

– 1.65V--2.2V V^CC(62WV2568ALL)

– 2.5V--3.6V V^CC(62WV2568BLL)

Easy memory expansion is provided by using Chip Enable

and Output Enable inputs. The active LOW Write Enable

(WE) controls both writing and reading of the memory.

• Fully static operation: no clock or refresh

required

TheIS62WV2568ALLandIS62WV2568BLLarepackaged

in the JEDEC standard 32-pin TSOP (TYPE I), sTSOP

(TYPE I), and 36-pin mini BGA.

• Three state outputs

• Industrial temperature available

• Lead-free available
