• Reprogrammable by the user via 10-pin ICP header
The NXP LCD Demo is a reference design for a low cost microcontroller and LCD solution. The
two main NXP parts used in this design can be purchased for less than $1.50 in 1,000 unit
quantities and only a few other external components are required. The Demo Board is controlled
by a simple two-button user interface (MODE and SELECT). The Demo Board CD includes
example code for several sample applications: an FM Radio display during a simulated channel
scan, a 15 minute count down timer, a repeating pattern of 4 text lines and a scrolling message
window. The user can edit this code and download to the reprogrammable Flash microcontroller
via a 10-pin header included on the board using any external ICP style programmer. A small USB
based ICP programmer that allows ICP programming of the P89LPC9103 and many other NXP
microcontrollers from any PC with a USB port is also available from Future Designs, Inc. Details
