SPEED

(ns)

The BS62UV2001 is a high performance, Ultra low power CMOS

Static Random Access Memory organized as 262,144 words by 8 bits

and operates from a wide range of 1.8V to 3.6V supply voltage.

Advanced CMOS technology and circuit techniques provide both high

speed and low power features with a typical CMOS standby current of

0.1uA and maximum access time of 70ns in 3.0V operation.

Easy memory expansion is provided by an active LOW chip

enable (CE1), an active HIGH chip enable (CE2), and active LOW

output enable (OE) and three-state output drivers.

The BS62UV2001 has an automatic power down feature, reducing the

power consumption significantly when chip is deselected.

The BS62UV2001 is available in the JEDEC standard 32 pin

450mil Plastic SOP, 8mmx13.4mm STSOP and 8mmx20mm TSOP.
