The BS62UV4000 is a high performance, ultra low power CMOS
Static Random Access Memory organized as 524,288 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
0.2uA and maximum access time of 70ns in 2.0V 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 BS62UV4000 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS62UV4000 is available in the JEDEC standard 32 pin SOP
, TSOP, TSOP II and STSOP
