LOW POWER 4M SRAM 512K BY 8
High Speed Super Low Power SRAM 512K Word By 8 Bit CS18LV40963 1 Rev. 2.3 Chiplus reserves the right to change product or specification without notice.
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 -8×13.4 mm, TSOP 1 -8x20mm, TSOP 2 -400mil and SOP -450 mil packages.
