- DESCRIPTION
The STC62WV51216 is a high performance, very low power CMOS Static Random Access Memory organized as 524,288 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 1.5u A at 3V/25o C and maximum access time of 55ns at 3.0V/85o C. Easy memory expansion is provided by an active LOW chip enable (CE) ,active LOW output enable(OE) and three-state output drivers. The STC62WV51216 has an automatic power down feature, reducing the power consumption significantly when chip is deselected. The STC62WV51216 is available in 48B BGA and 44L TSOP2 packages.
