Very Low Power/Voltage CMOS SRAM
2M X 8 bit
GENERAL DESCRIPTION
BS62LV1605
• Vcc operation voltage : 4.5V ~ 5.5V
• Very low power consumption :
Vcc = 5.0V C-grade: 113mA (@55ns) operating current
I -grade: 115mA (@55ns) operating current
C-grade: 90mA (@70ns) operating current
I -grade: 92mA (@70ns) operating current
15uA (Typ.) CMOS standby current
• High speed access time :
-55
55ns
-70
70ns
• 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 BS62LV1605 is a high performance , very low power CMOS Static
Random Access Memory organized as 2048K words by 8 bits and
operates from a 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
15uA at 5.0V/25
o
C and maximum access time of 55ns at 5.0V/85
o
C.
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 BS62LV1605 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS62LV1605 is available in 48B BGA and 44L TSOP2 packages.
