DESCRIPTION
The DS2064 is a 65536鈥揵it low power, fully static ran-
dom access memory organized as 8192 words by eight
bits using CMOS technology. The device operates from
a single power supply with a voltage input between 4.5V
and 5.5V. The chip enable inputs (CE1 and CE2) are
used for device selection and can be used in order to
achieve the minimum standby current mode, which fa-
cilitates both battery operate and battery backup appli-
cations. The device provides fast access time of 200 ns
and is most suitable for low power applications where
battery operation or battery backup for nonvolatility are
required. The DS2064 is a JEDEC鈥搒tandard 8K x 8
SRAM and is pin鈥揷ompatible with ROM and EPROM of
similar density.
