„ DESCRIPTION
The BS616LV1611 is a high performance, very low power CMOS Static
Random Access Memory organized as 1,048,576 words by 16 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 3.0uA at 3V/25^oC and maximum access time of 55ns at 3.0V/85^oC.
Easy memory expansion is provided by an active LOW chip enable(CE1)
, active HIGH chip enable (CE2), active LOW output enable(OE) and
three-state output drivers.
The BS616LV1611 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616LV1611 is available in 48-pin BGA package.
