Ultra Low Power/Voltage CMOS SRAM
256K X 8 bit
BSI
BS62UV2001
DESCRIPTION
FEATURES
The BS62UV2001 is a high performance, Ultra low power CMOS
Static Random Access Memory organized as 262,144 words by 8 bits
and operates from a wide range of 1.8V 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
0.1uA and maximum access time of 70ns in 3.0V operation.
• Wide Vcc operation voltage : 1.8V ~ 3.6V
• Ultra low power consumption :
Vcc = 2.0V C-grade : 15mA (Max.) operating current
I- grade : 20mA (Max.) operating current
0.08uA (Typ.) CMOS standby current
Vcc = 3.0V C-grade : 20mA (Max.) operating current
I- grade : 25mA (Max.) operating current
0.1uA (Typ.) CMOS standby current
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.
• High speed access time :
The BS62UV2001 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.

450mil Plastic SOP, 8mmx13.4mm STSOP and 8mmx20mm TSOP.
• 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 CE2, CE1, and OE options
