• Automatic power down when chip is deselected

• Three state outputs and TTL compatible

• Fully static operation

• Data retention supply voltage as low as 1.5V

• Easy expansion with CE2, CE1, and OE options

The BS62LV1028 is a high performance, very low power CMOS

Static Random Access Memory organized as 131,072 words by 8 bits

and operates from a wide range of 2.4V 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

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 BS62LV1028 has an automatic power down feature, reducing the

power consumption significantly when chip is deselected.

The BS62LV1028 is available in DICE form , JEDEC standard 32 pin

450mil Plastic SOP, 300mil Plastic SOJ, 600mil Plastic DIP, 8mmx13.4

mm STSOP and 8mmx20mm TSOP.
