DESCRIPTION
The XM28C040P is a high density CMOS byte alter-
able nonvolatile memory array constructed on a co-
fired ceramic substrate using Xicor’s 128K x 8 compo-
nents in 32-pad leadless chip carriers. The Substrate is
a 66-pin ceramic pin grid array.
The module is configured with four separate chip
enable and write enable inputs and 32 separate I/Os.
This, along with the small footprint, provides the end
user with a large degree of flexibility in board layout and
memory configuration. In addition, with the large num-
ber of pins and the growth path being implemented, the
module will be able to grow to 16 megabits.
