DESCRIPTION
The
μ
Port Saver memories need no serial ports or special
hardware and connect to the processor memory bus.
Replacing bytewide data memory, the
μ
Port Saver uses
bytewide memory control functions, takes a fraction of
the board space and consumes much less power.
Replacing serial memories, the
μ
Port 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
μ
Port Saver memory outputs data within 25ns 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 10
MHz, the
μ
Port Saver supplies data faster than required by
most host read cycle specifications. This eliminates
the need for software NOPs.
The
μ
Port 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
μ
Port
Saver to work well in 8-bit, 16 bit, 32-bit, and 64-bit
systems.
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.
