-55
55ns
-70
70ns
• Automatic power down when chip is deselected
• Three state outputs and TTL compatible
• Fully static operation

• I/O Configuration x8/x16 selectable by LB and UB pin
DESCRIPTION
The BS616LV4018 is a high performance, very low power CMOS Static
Random Access Memory organized as 262,144 words by 16 bits and
operates from a range of 4.5V 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
2.0uA at 5.0V/25
o
C and maximum access time of 55ns at 5.0V/85
o
C.
Easy memory expansion is provided by an active LOW chip enable (CE)
,active LOW output enable(OE) and three-state output drivers.
The BS616LV4018 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616LV4018 is available in DICE form , JEDEC standard 44-pin
TSOP Type II package and 48-ball BGA package.
