Introduction
This document applies to revision 2.2 evaluation boards.
This evaluation board is intended to be used to:
●
enable quick evaluate and debugging of software for the SPEAr1340 embedded MPU
●
act as a learning tool for rapid familiarity with the features of the SPEAr1340
●
provide a reference design to use as a starting point for the development of a final
application board
The EVALSP1340CPU board is equipped with interfaces to the high-speed peripherals
embedded in SPEAr1340 device.
