SAMA5D2 SIP

SAMA5D2 System in Package (SIP) MPU with up to 1 Gbit

DDR2 SDRAM or 2 Gbit LPDDR2 SDRAM

Scope

This document is an overview of the main features of the SAMA5D2 SIP. The sole reference documents for product

information on the SAMA5D2 and the LPDDR2/DDR2-SDRAM memories are listed in the table below.

Introduction

The SAMA5D2 System-In-Package (SIP) integrates the Arm

® Cortex®-A5 processor-based SAMA5D2 MPU with up

to 1 Gbit DDR2-SDRAM or up to 2 Gbit LPDDR2-SDRAM in a single package.

By combining the high-performance, ultra-low power SAMA5D2 with LPDDR2/DDR2-SDRAM in a single package,

PCB routing complexity, area and number of layers is reduced in the majority of cases. This makes board design

easier and more robust by facilitating design for EMI, ESD and signal integrity.

DDR2-SDRAM memory sizes and package options available

• 128 Mbit, TFBGA196

• 512 Mbit and 1 Gbit, TFBGA289

LPDDR2-SDRAM memory sizes and package options available

• 1 Gbit and 2 Gbit, TFBGA361

While the smallest option targets applications with a small OS or bare metal, the larger options are suitable for

applications using Linux®.
