„ DESCRIPTION
The BS62LV1027 is a high performance, very low power CMOS
Static Random Access Memory organized as 131,072 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 1.5/5uA at Vcc=3V/5V at 85 OC and maximum access time
of 55/70ns .
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 BS62LV1027 has an automatic power down feature, reducing
the power consumption significantly when chip is deselected.
The BS62LV1027 is available in DICE form, JEDEC standard 32 pin
450mil Plastic SOP, 600mil Plastic DIP, 8mmx13.4mm STSOP, and
8mmx20mm TSOP Package
