FEATURES

Very Low Power/Voltage CMOS SRAM

128K x 16 or 256K x 8 bit switchable

DESCRIPTION

BS616LV2021

• Very low operation voltage : 2.4 ~ 5.5V

• Very low power consumption :

Vcc = 3.0V

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

I-grade: 25mA (Max.) operating current

0.1uA (Typ.) CMOS standby current

Vcc = 5.0V

C-grade: 40mA (Max.) operating current

I-grade: 45mA (Max.) operating current

0.6uA (Typ.) CMOS standby current

• High speed access time :

-70

70ns (Max.) at Vcc = 3.0V

-10

100ns (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 CE1, CE2 and OE options

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

The BS616LV2021 is a high performance, very low power CMOS Static

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

262,144 bytes by 8 bits selectable by CIO pin 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 0.1uA and maximum access time of 70/100ns in 3V operation.

Easy memory expansion is provided by active HIGH chip

enable2(CE2), active LOW chip enable1(CE1), active LOW output

enable(OE) and three-state output drivers.

The BS616LV2021 has an automatic power down feature, reducing the

power consumption significantly when chip is deselected.

The BS616LV2021 is available in DICE form and 48-pin BGA type.
