PRODUCT FAMILY
The
STC62WV256
is a high performance , very low power CMOS
Static Random Access Memory organized as 32,768 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
0.01uA and maximum access time of 70ns in 3V operation.
Easy memory expansion is provided by active LOW chip enable (CE),
active LOW output enable (OE) and three-state output drivers.
The
STC62WV256
has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The
STC62WV256
is available in the DICE form, JEDEC standard 28pin
330mil Plastic SOP, 300mil Plastic SOJ, 600mil Plastic DIP and 8mmx
13.4mm TSOP (normal type).
