Preliminary Information

ICmic

This X84160/640/128 device has been acquired by

IC MICROSYSTEMS from Xicor, Inc.

Advanced MPS™ Micro Port Saver EEPROM with Block Lock™ Protection

FEATURES

bytewide memory control functions, takes a fraction of

the board space and consumes much less power.

•Up to 15MHz data transfer rate

Replacing serial memories, the µPort Saver provides all the

•20ns Read Access Time

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

•Direct Interface to Microprocessors and

Microcontrollers

—Eliminates I/O port requirements

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

—No interface glue logic required

—Eliminates need for parallel to serial converters

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

prevents bottlenecks on the bus. With rates to

•Low Power CMOS

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

—Standby Current Less than 1µA

15MHz, the µPort Saver supplies data faster than

required by most host read cycle specifications. This

eliminates the need for software NOPs.

—Active Current Less than 1mA

•Byte or Page Write Capable

—32-Byte Page Write Mode

The µPort Saver memories communicate over one line of the

data bus using a sequence of standard bus read and

•New Programmable Block Lock™ Protection

—Software Write Protection

—Programmable Hardware Write Protection

write operations. This “bit serial” interface allows the

µPort Saver to work well in 8-bit, 16 bit, 32-bit, and 64-bit

systems.

•Block Lock (0, 1/4, 1/2, or all of the array)

•Typical Nonvolatile Write Cycle Time: 3ms

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

•High Reliability

—100,000 Endurance Cycles

—Guaranteed Data Retention: 100 Years

•Small Package Options

—8-Lead Mini-DIP Package

—8, 14-Lead SOIC Packages

—8, 20, 28-Lead TSSOP Packages

—8-Lead XBGA Packages

A Write Protect (WP) pin prevents inadvertent writes to the

memory.

DESCRIPTION

Xicor EEPROMs are designed and tested for

applications requiring extended endurance. Inherent data

retention is greater than 100 years.

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
