„ DESCRIPTION
The BS62UV256 is a high performance, ultra low power CMOS
Static Random Access Memory organized as 32,768 words by 8 bits
and operates from a wide range of 1.8V to 3.6V supply voltage.
Advanced CMOS technology and circuit techniques provide both high
speed and low power features with a typical CMOS standby current of
0.005uA and maximum access time of 150ns in 2V operation.
Easy memory expansion is provided by an active LOW chip
enable (CE), and active LOW output enable (OE) and three-state
output drivers.
The BS62UV256 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS62UV256 is available in the JEDEC standard 28 pin
330mil Plastic SOP, 8mmx13.4mm TSOP (normal type), 300mil Plastic
SOJ and 600mil Plastic DIP.
