High Speed Super Low Power SRAM
512K Word By 8 Bit
CS18LV40963
GENERAL DESCRIPTION
The CS18LV40963 is a high performance, high speed, and super low power CMOS Static
Random Access Memory organized as 524,288 words by 8 bits and operates from a wide range of
2.7 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 0.50uA and maximum
access time of 55/70ns in 3.0V operation. Easy memory expansion is provided by an active LOW
chip enable (/CE) and active LOW output enable (/OE) and three-state output drivers.
The CS18LV40963 has an automatic power down feature, reducing the power consumption
significantly when chip is deselected. The CS18LV40963 is available in JEDEC standard 32-pin
sTSOP 1 -8x13.4 mm, TSOP 1 -8x20mm, TSOP 2 -400mil, SOP -450 mil and WSON –8x8mm
packages.
