„ DESCRIPTION
The STC62WV5128 is a high performance, very low power CMOS
Static Random Access Memory organized as 524,288 words by 8 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
0.45uA at 3.0V/25^oC and maximum access time of 55ns at 3.0V/85^oC.
Easy memory expansion is provided by an active LOW chip enable
(CE) , and active LOW output enable (OE) and three-state output
drivers.
The STC62WV5128 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The STC62WV5128 is available in the JEDEC standard 32L SOP, TSOP
, PDIP, TSOP II and STSOP package.
