The BS62LV4005 is a high performance, low power CMOS

Static Random Access Memory organized as 524,288 words by 8 bits

and operates from a wide range of 4.5V to 5.5V supply voltage.

Advanced CMOS technology and circuit techniques provide both high

speed and low power features with maximum access time of 55/ 70ns

in 5V operation.

Easy memory expansion is provided by active LOW chip

enable (CE), active LOW output enable (OE) and three-state

output drivers.

The BS62LV4005 has an automatic power down feature, reducing the

power consumption significantly when chip is deselected.

The BS62LV4005 is available in the JEDEC standard 32 pin SOP

, TSOP, TSOP II and STSOP .
