R0201-BS616LV1615
Very Low Power/Voltage CMOS SRAM
1M X 16 bit (Dual CE Pins)
The BS616LV1615 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 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/25
o
C and maximum access time of 55ns at 5.0V/85
o
C.
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 BS616LV1615 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616LV1615 is available in 48-pin BGA package.
