2. Scope

This document describes the most important hardware features of the StampA5D3x. It includes all informations necessary to develop a customer specific hardware for the StampA5D3x. The Operating System Linux is described in a further document.

The AT91SAMA5D3x processor series consists of several MPUs, like the SAMA5D31, SAMA5D35 and SAMA5D36. Not all processors will be implemented as a Stamp CPU module, but these processors only vary in their variety of peripherals. The differences in peripherals are displayed in the following table.

Peripherals SAMA5D31 SAMA5D33 SAMA5D34 SAMA5D35 SAMA5D36

If a peripheral relates only to a specific MPU it will be declared in it's description.

The manual comprises only a brief description of the AT91SAMA5D3x processor, as this is already described in depth in the manual of the manufacturer Atmel®. Descriptions of the ARM® core Cortex-A5 are available from Atmel® and also at http://www.arm.com. It is much recommended to have a look at these documents for a thorough understanding of the processor and its integrated peripherals.
