R0201-BS616LV2018

Very Low Power/Voltage CMOS SRAM

128K X 16 bit

• Very low operation voltage : 2.4 ~ 3.6V

• Very low power consumption :

Vcc = 3.0V

C-grade: 16mA (Max.) operating current

I -grade: 20mA (Max.) operating current

0.1uA (Typ.) CMOS standby current

• High speed access time :

-70

70ns (Max.) at Vcc = 3.0V

• 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 CE and OE options

• I/O Configuration x8/x16 selectable by LB and UB pin

The BS616LV2018 is a high performance, very low power CMOS Static

Random Access Memory organized as 131,072 words by 16 bits and

operates from a wide range of 2.4V 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 0.1uA and maximum access time of 70ns in 3V operation.

Easy

memory

expansion is

provided by active LOW chip

enable(CE), active LOW output enable(OE) and three-state output

drivers.

The BS616LV2018 has an automatic power down feature, reducing the

power consumption significantly when chip is deselected.

The BS616LV2018 is available in DICE form, JEDEC standard 48-pin

TSOP Type I package and 48-ball BGA package.
