DESCRIPTION
The
cial hardware and connect to the processor memory bus.
Replacing bytewide data memory, the
bytewide memory control functions, takes a fraction of
the board space and consumes much less power.
Replacing serial memories, the
the serial benefits, such as low cost, low power, low volt-
age, and small package size while releasing I/Os for
more important uses.
μ
Port Saver memories need no serial ports or spe-
μ
Port Saver uses
μ
Port Saver provides all
The
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.
μ
Port Saver memory outputs data within 25ns of an
The
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.
μ
Port Saver memories communicate over one line of
A Write Protect (WP) pin prevents inadvertent writes to
the memory.
Xicor EEPROMs are designed and tested for applica-
tions requiring extended endurance. Inherent data reten-
tion is greater than 100 years.
