Very Low Power/Voltage CMOS SRAM
512K x 16 or 1M x 8 bit switchable
BS616LV8023
R0201-BS616LV8023
The BS616LV8023 is a high performance, very low power CMOS Static
Random Access Memory organized as 524,288 words by 16 bits or
1,048,576 bytes by 8 bits selectable by CIO pin and operates from a wide
range of 2.4V to 3.6V supply voltage.
Advanced CMOS technology and circuit techniques provide both high
speed and low power features with a typical CMOS standby current
of 0.5uA and maximum access time of 70/100ns in 3.0V operation.
Easy memory expansion is provided by an active HIGH chip
enable2(CE2), active LOW chip enable1(CE1), active LOW output
enable(OE) and three-state output drivers.
The BS616LV8023 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616LV8023 is available in 48-pin BGA type.
