1. Introduction
The SOMDIMM‐LPC2478 provides a quick and easy solution for implementing an ARM7TDMI‐S based design by
providing the basic functions necessary for a product on an easy to use SOMDIMM. The SOMDIMM uses an
industry standard 200 pin SO‐DIMM interface. These sockets are utilized by virtually every laptop on the market.
This SOMDIMM is compatible with FDI’s Family of Touch Screen LCD Kits but can also be used for custom platform
development or customer applications.

4. ESD Warning
The DK‐TS‐KIT shipped in a protective anti‐static package. The kit must not be subjected to high electrostatic
potentials. Damage may occur to the boards that will not be covered under warranty. General practice for working
with static sensitive devices should be followed when working with the DK‐TS‐KIT.
5. Requirements
The SOMDIMM‐LPC2478 requires a carrier board with a 200‐pin SO‐DIMM socket. The socket should have the key
at the 1.8V location (the SOMDIMM‐LPC2478 doesn’t require 1.8V). The CARRIER Board from Future Designs
provides this socket and should be utilized to develop your application for initial verification.
Example SO‐DIMM Socket Manufacturer and Part Number: TYCO 1473005‐4
Please refer to section 10 for the pin out details of the SOMDIMM Edge Finger.
