Description
The UC62WV0256 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
2.7V to 5.6V supply voltage. Advanced CMOS technology
and circuit techniques provide both high speed and low
power features with a typical CMOS standby current of 1uA
and maximum access time of 70ns in 2.0V operation.
Easy memory expansion is provided enable (CE), and
active LOW output enable (OE) and three-state output
drivers.
The UC62WV0256 has an automatic power down
feature, reducing the power consumption significantly when
chip is deselected.
The UC62WV0256 is available in the JEDEC standard 28 pin
330mil Plastic SOP, 300mil Plastic SOJ, 600mil Plastic DIP
and 8mmx13.4mm TSOP (normal type).
