µPort Saver EEPROM

FEATURES

DESCRIPTION

•Up to 10MHz data transfer rate

•25ns Read Access Time

The µPort Saver memories need no serial ports or special

hardware and connect to the processor memory bus.

•Direct Interface to Microprocessors and

Microcontrollers

—Eliminates I/O port requirements

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

—No interface glue logic required

—Eliminates need for parallel to serial converters

the serial benefits, such as low cost, low power, low voltage,

and small package size while releasing I/Os for

more important uses.

•Low Power CMOS

—1.8V–3.6V, 2.5V–5.5V and 5V 10% Versions

—Standby Current Less than 1µA

The µPort Saver memory outputs data within 25ns of an

active read signal. This is less than the read access time

—Active Current Less than 1mA

•Byte or Page Write Capable

of most hosts and provides “no-wait-state” operation. This

prevents bottlenecks on the bus. With rates to 10

—32-Byte Page Write Mode

•Typical Nonvolatile Write Cycle Time: 2ms

•High Reliability

MHz, the µPort Saver supplies data faster than required by

most host read cycle specifications. This eliminates

—100,000 Endurance Cycles

—Guaranteed Data Retention: 100 Years

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.
