FEATURES
DESCRIPTION
• Vcc operation voltage : 2.7 ~ 3.6V
• Very low power consumption :
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/25oC and maximum access time of 55ns at 3.0V/85oC .
This device provide three control inputs and three states output drivers
for easy memory expansion.
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 :

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.
• 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
