BSI VeryLowPower/VoltageCMOSSRAM

1M x 16 or 2M x 8 bit switchable

The BS616LV1626 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 4.5V 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 15uA at 5.0V/25oC and maximum access time of 55ns at 5.0V/85oC .

This device provide three control inputs and three states output drivers

for easy memory expansion.

The BS616LV1626 has an automatic power down feature, reducing the

power consumption significantly when chip is deselected.

The BS616LV1626 is available in 48-pin 12mmx20mm TSOP1 package.

• Vcc operation voltage : 4.5 ~ 5.5V

• Very low power consumption :

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 :
