DESCRIPTION
The BS62LV256 is a high performance, very low power CMOS Static
Random Access Memory organized as 32,768 by 8 bits and
operates form 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 maximum CMOS standby
current of 0.7uA/5uA at 3V/5V at 85
OC and maximum access time of
55/70ns.
Easy memory expansion is provided by an active LOW chip enable
(CE), and active LOW output enable (OE) and three-state output
drivers.
The BS62LV256 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS62LV256 is available in DICE form, JEDEC standard 28 pin
330mil Plastic SOP, 600mil Plastic DIP, 8mmx13.4mm TSOP
(normal type).
