BSI
FEATURES
Very Low Power/Voltage CMOS SRAM
1M x 16 or 2M x 8 bit switchable
DESCRIPTION
BS616LV1623
• Vcc operation voltage :
2.7 ~ 3.6V
• Very low power consumption :
Vcc =
3.0V
C-grade: 45mA (@55ns) operating current
I -grade: 46mA (@55ns) operating current
C-grade: 36mA (@70ns) operating current
I -grade: 37mA (@70ns) operating current
3.0uA (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
• I/O Configuration x8/x16 selectable by CIO, LB and UB pin
The BS616LV1623 is a high performance, very low power CMOS Static
Random Access Memory organized as 1,048,676 words by 16 bits or
2,097,152 bytes by 8 bits selectable by CIO pin and operates in a Vcc
range of
2.7V to 3.6V
supply voltage.
Advanced CMOS technology and circuit techniques provide both high
speed and low power features with a typical CMOS standby current
of
3.0uA
at
3.0V/25
o
C
and maximum access time of 55ns at
3.0V/85
o
C
.
This device provide three control inputs and three states output drivers
for easy memory expansion.
The BS616LV1623 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616LV1623 is available in 48-pin 12mmx20mm TSOP1 package.
