FEATURES

DESCRIPTION

™

• CONCURRENT READ WRITE

The X68C64 is an 8K x 8 E PROM fabricated with

advanced CMOS Textured Poly Floating Gate Technol-

ogy. The X68C64 features a Multiplexed Address and

Data bus allowing a direct interface to a variety of

popular single-chip microcontrollers operating in ex-

panded multiplexed mode without the need for addi-

tional interface circuitry.

—Dual Plane Architecture

—Isolates Read/Write Functions

Between Planes

—Allows Continuous Execution of Code

From One Plane While Writing in

the Other Plane

• Multiplexed Address/Data Bus

—Direct Interface to Popular 8-bit

Microcontrollers, e.g., Motorola M6801/03,

M68HC11 Family

• High Performance CMOS

—Fast Access Time, 120ns

—Low Power

TheX68C64isinternallyconfiguredastwoindependent

4K x 8 memory arrays. This feature provides the ability

toperformnonvolatilememoryupdatesinonearrayand

continue operation out of code stored in the other array;

effectively eliminating the need for an auxiliary memory

device for code storage.

—60mA Maximum Active

To write to the X68C64, a three-byte command

sequence must precede the byte(s) being written. The

X68C64 also provides a second generation software

data protection scheme called Block Protect. Block

Protect can provide write lockout of the entire device or

selected 1K blocks. There are eight 1K x 8 blocks that

can be write protected individually in any combination

required by the user. Block Protect, in addition to Write

Controlinput,allowsthedifferentsegmentsofthememory

to have varying degrees of alterability in normal system

operation.

—500µA Maximum Standby

• Software Data Protection

• Block Protect Register

—Individually Set Write Lock Out in 1K Blocks

• Toggle Bit Polling

—Early End of Write Detection

• Page Mode Write

—Allows up to 32 Bytes to be Written in

One Write Cycle

• High Reliability

—Endurance: 100,000 Write Cycles

—Data Retention: 100 Years
