n DESCRIPTION
The BS62LV2006 is a high performance, very low power CMOS
Static Random Access Memory organized as 262,144 by 8 bits and
operates form a wide range of 2.4V to 5.5V supply voltage.
Advanced CMOS technology and circuit techniques provide both
high speed and low power features with typical CMOS standby
current of 0.1uA at 3.0V/25^OC and maximum access time of 55ns at
3.0V/85^OC.
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 BS62LV2006 has an automatic power down feature, reducing
the power consumption significantly when chip is deselected.
The BS62LV2006 is available in DICE form, JEDEC standard 32 pin
450mil Plastic SOP, 8mmx13.4mm STSOP, 8mmx20mm TSOP and
36-ball BGA package.
