DESCRIPTION
The X86C64 is an 8K x 8 E
2
PROM fabricated with
advanced CMOS Textured Poly Floating Gate Technol-
ogy. The X86C64 features a Multiplexed Address and
Data bus allowing direct interface to a variety of popular
single-chip microcontrollers operating in expanded mul-
tiplexed mode without the need for additional interface
circuitry.
The X86C64 is internally configured as two indepen-
dent 4K x 8 memory arrays. This feature provides the
ability to perform nonvolatile memory updates in one
array and continue operation out of code stored in the
other array; effectively eliminating the need for an aux-
iliary memory device for code storage.
To write to the X86C64, a three byte command
sequence must precede the byte(s) being written. The
X86C64 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
Control input, allows the different segments of the
memory to have varying degrees of alterability in nor-
mal system operation.
