R0201-BS62LV4006
Very Low Power/Voltage CMOS SRAM
512K X 8 bit
• Wide Vcc operation voltage : 2.4V ~ 5.5V
• Very low power consumption :
Vcc = 3.0V C-grade: 29mA (@55ns) operating current
I -grade: 30mA (@55ns) operating current
C-grade: 24mA (@70ns) operating current
I -grade: 25mA (@70ns) operating current
0.45uA (Typ.) CMOS standby current
Vcc = 5.0V C-grade: 68mA (@55ns) operating current
I -grade: 70mA (@55ns) operating current
C-grade: 58mA (@70ns) operating current
I -grade: 60mA (@70ns) operating current
2.0uA (Typ.) CMOS standby current
• High speed access time :
-55 55ns
-70 70ns
• Automatic power down when chip is deselected
• Fully static operation
The BS62LV4006 is a high performance, very low power CMOS
Static Random Access Memory organized as 524,288 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
0.45uA at 3.0V/25oCand maximum access time of 55ns at 3.0V/85oC.
Easy memory expansion is provided by an active LOW chip enable
(CE) , and active LOW output enable (OE) and three-state output
drivers.
The BS62LV4006 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS62LV4006 is available in the JEDEC standard 32L SOP, TSOP
, PDIP, TSOP II and STSOP package.
