R0201-BS62LV8000
Very Low Power/Voltage CMOS SRAM
1M X 8 bit
Wide Vcc operation voltage : 2.4V ~ 5.5V
Very low power consumption :
Vcc = 3V C-grade: 20mA (Max.) operating current
I -grade: 25mA (Max.) operating current
0.5uA (Typ.) CMOS standby current
Vcc = 5V C-grade: 45mA (Max.) operation current
I -grade: 50mA (Max.) operating current
3uA (Typ.) CMOS standby current
High speed access time :
-70 70ns (Max) at Vcc = 3V
-10 100ns (Max) at Vcc = 3V
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
The BS62LV8000 is a high performance, very low power CMOS
Static Random Access Memory organized as 1,048,576 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
0.5uA 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.
The BS62LV8000 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS62LV8000 is available in 44 pin TSOP2 and 48-pin BGA type.
