• Data retention supply voltage as low as 1.5V
• Easy expansion with CE and OE options
• Three state outputs and TTL compatible
The BS62LV4006 is a high performance, very low power CMOS
Static Random Access Memory organized as 524,288 words by 8 bits
and operates from 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 a typical CMOS standby current of
0.45uA at
Easy memory expansion is provided by an active LOW chip enable
(CE) , and active LOW output enable (OE) and three-state output
drivers.
The BS62LV4006 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS62LV4006 is available in the JEDEC standard 32L SOP, TSOP
, PDIP, TSOP II and STSOP package.
