„ POWER CONSUMPTION
„ DESCRIPTION
The BS62LV1600 is a high performance, very low power CMOS
Static Random Access Memory organized as 2048K 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 16/100uA at Vcc=3/5V 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 BS62LV1600 has an automatic power down feature, reducing
the power consumption significantly when chip is deselected.
The BS62LV1600 is available in JEDEC standard 44-pin TSOP II
and 48-ball BGA package.
