Scope

This document is an overview of the main features of the SAM9X75 SiP microprocessor. The sole reference

documents for product information on SAM9X7 Series microprocessors and DDR3L SDRAM memories are listed

in Reference Documents.

Introduction

The SAM9X75 SiP integrates the ARM926 Arm® processor-based SAM9X75 MPU with an up to 2-Gbit DDR3L

SDRAM. By combining the SAM9X75 with a DDR SDRAM in a single package, PCB routing complexity, area and

number of layers are reduced in the majority of cases. This makes board design easier and more robust by

facilitating design for EMI, ESD and signal integrity.

The following SDRAM memory types and densities are available:

• 1-Gbit DDR3L SDRAM

• 2-Gbit DDR3L SDRAM
