BSI ^{Very Low Power/Voltage CMOS SRAM}
512K X 16 bit
BS616LV8011
„ FEATURES
• Very low operation voltage : 2.7 ~ 3.6V
• Very low power consumption :
Vcc = 3.0V C-grade: 40mA (Max.) operating current
I-grade : 50mA (Max.) operating current
1uA (Typ.) CMOS standby current
• High speed access time :
-70
70ns (Max.) at Vcc=3.0V
-10 100ns (Max.) at Vcc=3.0V
• 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 CE1,CE2 and OE options
„ DESCRIPTION
The BS616LV8011 is a high performance, very low power CMOS Static
Random Access Memory organized as 524,288 words by 16 bits and
operates from a wide range of 2.7V 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 1uA and maximum access time of 70/100ns in 3V operation.
Easy memory expansion is provided by an active LOW chip
enable(CE1,CE2) and active LOW output enable(OE) and three-state
output drivers.
The BS616LV8011 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616LV8011 is available in 48-pin BGA package.
