DESCRIPTION
The BS62UV256 is a high performance, ultra low power CMOS
Static Random Access Memory organized as 32,768 by 8 bits and
operates form 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 typical CMOS standby
current of 0.005uA and maximum access time of 150ns 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 BS62UV256 has an automatic power down feature, reducing
the power consumption significantly when chip is deselected.
The BS62UV256 is available in DICE form, JEDEC standard 28 pin
330mil Plastic SOP, 600mil Plastic DIP, 8mmx13.4mm TSOP
(normal type).
