„ DESCRIPTION
The STC62WV12816 is a high performance , very low power CMOS Static
Random Access Memory organized as 131,072 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
0.3uA at 3.0V /25^oC and maximum access time of 55ns at 3.0V / 85^oC.
Easy memory expansion is provided by active LOW chip enable (CE),
active LOW output enable(OE) and three-state output drivers.
The STC62WV12816 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The STC62WV12816 is available in DICE form , JEDEC standard 44-pin
TSOP Type II package and 48-ball BGA package.
