MYIR has released an Atmel SAMA5D3 ARM Cortex-A5 Development Board since April
2013 which has well received by customers worldwide. The board has one carrier
board to support four different CPU modules for SAMA5D3 series processors. It is
capable of running Linux and Android operating systems and offered with optional
4.3- and 7-inch LCD panels. It can work in harsh environment supporting -40 to
+85°C extended temperature operation.
The Cortex-A5 core has its special superiority besides performance compared to
Cortex-A8, Cortex-A9 and A15.
According to ARM official data, the ARM Cortex-A5 processor is the smallest,
lowest cost and lowest power ARMv7 application processor capable of delivering
the internet to the widest possible range of devices: from low-cost entry-level
smartphones, feature phones and smart mobile devices, to pervasive embedded
consumer and industrial devices.
It provides a high-value migration path for existing ARM926EJ-S™

ARM1176JZ-S™
http://www.arm.com/products/processors/classic/arm11/arm1176.php processor
designs. It achieves better than ARM1176JZ-S
http://www.arm.com/products/processors/classic/arm11/arm1176.php performance,
better power and energy efficiency than the ARM926EJ-S
http://www.arm.com/products/processors/classic/arm9/arm926.php, and 100%
Cortex-A http://www.arm.com/products/processors/cortex-a/index.php
compatibility.
The Cortex-A5 processor provides full instruction and feature compatibility
with the higher performance Cortex-A8, Cortex-A9, and Cortex-A15 processors -
all the way down to the operating system level. The Cortex-A5 processor also
maintains backwards application compatibility with Classic ARM processors
including the ARM926EJ-S, ARM1176JZ-S, and ARM7TDMI®.
So whether from the size, energy efficiency or cost, we think Cortex-A5 should
be a good choice for industrial applications.
MYIR’s MYD-SAMA5D3X series development boards include four models:
MYD-SAMA5D31, MYD-SAMA5D33, MYD-SAMA5D34 and MYD-SAMA5D35. The four CPUs are
fully pin-to-pin compatible with each other only have some minor difference with
Ethernet, UART, LCD and CAN configuration settings. User can select according to
their requirement.

From above table, we can see if you need Gigabit Ethernet, except SAMA5D31,
other three all can support; if you need two CANs, Gigabit Ethernet but no need
LCD, SAMA5D35 is a good choice; if you want to evaluate the performance of this
industrial board, SAMA5D34 has the most complete functions.
