R0201-BS62LV1600

Very Low Power/Voltage CMOS SRAM

2M X 8 bit

• Wide Vcc operation voltage : 2.4V ~ 5.5V

• 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

Vcc = 5.0V C-grade: 113mA (@55ns) operating current

I -grade: 115mA (@55ns) operating current

C-grade: 90mA (@70ns) operating current

I -grade: 92mA (@70ns) operating current

15uA (Typ.) CMOS standby current

• High speed access time :

• Automatic power down when chip is deselected

The BS62LV1600 is a high performance , very low power CMOS Static

Random Access Memory organized as 2048K 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

Easy memory expansion is provided by an active LOW chip enable (CE1)

, an active HIGH chip enable (CE2) and active LOW output enable (OE)

and three-state output drivers.

The BS62LV1600 has an automatic power down feature, reducing the

power consumption significantly when chip is deselected.

The BS62LV1600 is available in 48B BGA and 44L TSOP2 packages.
