The X84041 MPS E2 is an attractive alternative to the
'add-on' parallel or serial nonvolatile memories that
have traditionally been used in microcontroller-based
systems. It features 4K bits of serial E2PROM
memory that is accessed via a standard parallel bus.
The serial architecture of the X84041 provides a cost
and space saving replacement for low density parallel
devices. Its unique parallel bus compatible interface
also offers an I/O-saving alternative to serial devices
that typically require two or three control pins for
communication purposes. Although the X84041 can be
used to interface with practically any 8, 16, or 32-bit
microcontroller, the code provided here is for the
widely used 8051 family.
