R0201-BS62LV8005
Very Low Power/Voltage CMOS SRAM
1M X 8 bit
• Wide Vcc operation voltage : 4.5V ~ 5.5V
• Very low power consumption :
Vcc = 5V C-grade: 45mA (Max.) operation current
I -grade: 50mA (Max.) operating current
3uA (Typ.) CMOS standby current
• High speed access time :
-55 55ns (Max) at Vcc = 5V
-70 70ns (Max) at Vcc = 5V
• 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 BS62LV8005 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 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
3uA and maximum access time of 55ns in 5V 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 BS62LV8005 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS62LV8005 is available in 44 pin TSOP2 and 48-pin BGA type.
