MPS^EEPROM

X84160/640/128

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.

Replacing serial memories, the µPort Saver provides all

the serial beneﬁts, such as low cost, low power, low volt-

age, and small package size while releasing I/Os for

more important uses.

• Up to 15MHz data transfer rate

• 20ns Read Access Time

• Direct Interface to Microprocessors and

Microcontrollers

—Eliminates I/O port requirements

—No interface glue logic required

—Eliminates need for parallel to serial converters

• Low Power CMOS

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

—Standby Current Less than 1µA

—Active Current Less than 1mA

• Byte or Page Write Capable

The µPort Saver memory outputs data within 20ns 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

15MHz, the µPort Saver supplies data faster than

required by most host read cycle speciﬁcations. This

eliminates the need for software NOPs.

—32-Byte Page Write Mode

• New Programmable Block Lock™ Protection

—Software Write Protection

—Programmable Hardware Write Protection

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

• Typical Nonvolatile Write Cycle Time: 3ms

• High Reliability

—100,000 Endurance Cycles

—Guaranteed Data Retention: 100Years

• Small Package Options

—8-Lead Mini-DIP Package

—8, 14-Lead SOIC Packages

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.

The X84160/640/128 provide additional data security

features through Block Lock and programmable Hard-

ware Write Protection. These allow some or all of the

array to be write protected by software command or by

hardware. System Conﬁguration, Company ID, calibra-

tion 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

—8, 20, 28-Lead TSSOP Packages

—8-Lead XBGA Packages

A Write Protect (WP) pin prevents inadvertent writes to

the memory.

DESCRIPTION

The µPort Saver memories need no serial ports or spe-

cial hardware and connect to the processor memory bus.

Replacing bytewide data memory, the µPort Saver uses

Xicor EEPROMs are designed and tested for applica-

tions requiring extended endurance. Inherent data reten-

tion is greater than 100 years.
