All I/O pins are 3V/5V tolerant
FEATURES
The BS62LV2001 is a high performance, very low power CMOS
Static Random Access Memory organized as 262,144 words by 8 bits
and operates in 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 a typical CMOS standby current of
0.1uA and maximum access time of 70ns in 3V operation.
Easy memory expansion is provided by an active LOW chip
enable (CE1), an active HIGH chip enable (CE2), and active LOW
output enable (OE) and three-state output drivers.
The BS62LV2001 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS62LV2001 is available in DICE form, JEDEC standard 32 pin
450mil Plastic SOP, 8mmx13.4mm STSOP, and 8mmx20mm TSOP.
