„ POWER CONSUMPTION
„ DESCRIPTION
The BS62LV8001 is a high performance, very low power CMOS
Static Random Access Memory organized as 1,048,576 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 8/50uA at Vcc=3/5V at 85OC 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 BS62LV8001 has an automatic power down feature, reducing
the power consumption significantly when chip is deselected.
The BS62LV8001 is available in DICE form, JEDEC standard 44-pin
TSOP II and 48-ball BGA package.
