„ FEATURES
• Vcc operation voltage : 4.5V ~ 5.5V
• Very low power consumption :
Vcc = 5.0V C-grade : 35mA (Max.) operating current
I- grade : 40mA (Max.) operating current
0.4uA (Typ.) CMOS standby current
• High speed access time :
-55
55ns (Max.) at Vcc = 5.0V
• 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 CE and OE options
• I/O Configuration x8/x16 selectable by LB and UB pin
„ DESCRIPTION
The BS616LV1015 is a high performance, very low power CMOS Static
Random Access Memory organized as 65,536 words by 16 bits and
operates from a wide 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 0.4uA and maximum access time of 55ns in 5V operation.
Easy memory expansion is provided by an active LOW chip
enable(CE) and active LOW output enable(OE) and three-state output
drivers.
The BS616LV1015 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616LV1015 is available in the JEDEC standard 44-pin TSOP
Type II and 48-pin BGA package.
