DESCRIPTION
The μPort Saver memories need no serial ports or special
hardware and connect to the processor memory bus.
Replacing bytewide data memory, the μPort Saver uses
bytewide memory control functions, takes a fraction of
the board space and consumes much less power.
Replacing serial memories, the μPort Saver provides all the
serial benefits, such as low cost, low power, low voltage,
and small package size while releasing I/Os for more
important uses.
The μPort Saver memory outputs data within 20ns of an
active read signal. This is less than the read access time
of most hosts and provides “no-wait-state” operation. This
prevents bottlenecks on the bus. With rates to
15MHz, the μPort Saver supplies data faster than
required by most host read cycle specifications. This
eliminates the need for software NOPs.
The μPort Saver memories communicate over one line of the
data bus using a sequence of standard bus read and
write operations. This “bit serial” interface allows the
μPort Saver to work well in 8-bit, 16 bit, 32-bit, and 64-bit
systems.
The X84160/640/128 provide additional data security
features through Block Lock and programmable Hardware
Write Protection. These allow some or all of the array to
be write protected by software command or by hardware.
System Configuration, Company ID, calibration information,
or other critical data can be secured against unexpected
or inadvertent program operations, leaving the remainder
of the memory available for the system or user access
A Write Protect (WP) pin prevents inadvertent writes to the
memory.
Xicor EEPROMs are designed and tested for
applications requiring extended endurance. Inherent data
retention is greater than 100 years.
