CPU Module (CM) Board
4.1
Overview
The CPU module (CM) board is the heart of the SAMA5D3x-EK. It connects to the main board through a SODIMM200
interface and integrates the SAMA5D3 series processor and external memories. The CM board serves as a minimal CPU
sub-system. All five SAMA5D31, SAMA5D33, SAMA5D34, SAMA5D35 and SAMA5D36 processors share the same CM
board circuitry with minor configuration settings.
The CM board connects to a carrier board containing its connectors, power supply and any expansion I/O through a
standard gold-plated SODIMM 200-pin connection.
Note:
There are five CM boards from three different manufacturers. The five processors are implemented as shown in
Table 4-1
.
The five CM boards share the same circuitry design with different designator information and PCB layouts. The circuitry
reference in this guide, for common design parts, refers to schematics from SAMA5D3 series-CM (mfg2). All the other
schematics are provided in the
Section 4.4 “Embest/Flextronics Schematics”
and
Section 4.5 “Ronetix Schematics”
.
