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 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

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.

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.
