Very Low Power/Voltage CMOS SRAM
128K X 8 bit
BSI
BS62LV1024
DESCRIPTION
FEATURES
• Wide Vcc operation voltage : 2.4V ~ 5.5V
• Very low power consumption :
The BS62LV1024 is a high performance, very low power CMOS
Static Random Access Memory organized as 131,072 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
0.02uA and maximum access time of 70ns in 3V operation.
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.
Vcc = 3.0V C-grade : 20mA (Max.) operating current
I- grade : 25mA (Max.) operating current
0.02uA (Typ.) CMOS standby current
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 :
-70
70ns (Max.) at Vcc = 3.0V
The BS62LV1024 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
• Automatic power down when chip is deselected
• Three state outputs and TTL compatible
• Fully static operation
The BS62LV1024 is available in DICE form, JEDEC standard 32 pin
450mil Plastic SOP, 300mil Plastic SOJ, 600mil Plastic DIP, 8mmx13.4mm
STSOP and 8mmx20mm TSOP.
• Data retention supply voltage as low as 1.5V
• EPasRyOexDpaUnCsiTonFwAithMCILE2Y, CE1, and OE options
