„ DESCRIPTION
The BS62LV1025 is a high performance, very low power CMOS
Static Random Access Memory organized as 131,072 words by 8 bits
and operates from a wide range of 4.5V 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
0.4uA and maximum access time of 55ns in 5V 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 BS62LV1025 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS62LV1025 is available in DICE form, JEDEC standard 32 pin
450mil Plastic SOP, 300mil Plastic SOJ, 600mil Plastic DIP,
8mmx13.4mm STSOP and 8mmx20mm TSOP.
