1. Introduction
USB-EK01 is designed as an evaluation board that can perform various tests using minimal memory
and I/O (refer to USB-EK01 User‟s Manual).
Internal 8K Byte memory was sufficient for most tests and applications, but there was a limit to
applications requiring large program capacity or large data memory. Therefore, it became necessary to
use external memory, and additional I/O expansion and the concept of allowing the user to change the
hardware configuration, we designed the USB-IK01 board that can be used by connecting to the
external expansion connector of the USB-EK01..
