DESCRIPTION
The XM28C010P is a high speed, high density CMOS
byte alterable nonvolatile memory array constructed on
a co-fired ceramic substrate using Xicor’s High Speed
32K x 8 components 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.
