Thanks dear for ur guidance
As I already have a board that is MCB2140 that is with lpc2148 on
board.
I need to interface LCD with traditional 11 pin way as 3 are control
lines and 8 datalines i.e. parellel interface but my problem is there
is no LCD on board and I have a 5V LCD, as lpc2148 is 5V tolerable
GPIO pins so I think I can interface LCD with this, and probably I
have to use pull-up for these pins.
and Well said as no one will design anything freely so tell me the
charges I need to interface traditional way LCD, one IR receiver for
my 10 button remote and 4MB of NV RAM and 4 pushbutton keys on port
as it seems very simple but I want to concentrate on programming part
only so dont want to give my time for hardware.

Pankaj:
I don't think that you will find anyone who would design something for
you free of charge, since there is a lot of work involved. If you
want something now then I would suggest going for one of the ready-
made development boards that come with all the hardware and software
required to get started.
You can see a (partial) list of available kits on a page on my website:
But before you even go there perhaps we should discuss your project
requirements first before we start figuring out what you want to
buy/build. What is this for, and what is needed? 4MB of non-voltaile
ram seems like a lot, is this actually required as RAM or just for
storage?

Pankaj,
If you need to be running quickly, Signum Systems has LPC2138 board
($195) available with 2x16 LCD, battery backed-up timer, speaker output
and many other useful open-source software (I2C, time-of-day,
interrupts, etc.)
The parallel bus LCD is connected to LPC2138 via PCA9555 I2C controller.
The board manual is on www.signum.com/lpc2138.htm but if you need
schematics, let me know. I think it should be relatively easy to apply
it to the LPC2214.
BTW - the board comes with a all GNU tools ready to re-compile the
project under Windows, so you do not have to waste time converting it
for another compiler.

Dear ARMiessssss..
I am very new to ARM world and here I need to interface 20X2 character
LCD module, and 4 MB Non Volatile RAM with LPC2214 as well as Full
modem DB9 connector,so can anybody design the schematic for me as I
can go easy with programming but hardware is little bit tough for me.
