1 Introduction
SMARC
2.0 Concept
The SMARC (“Smart Mobility ARChitecture”) is a versatile small form factor computer
Module definition targeting applications that require low power, low costs, and high
performance. The Modules will typically use ARM SOCs similar or the same as those used in
many familiar devices such as tablet computers and smart phones. Alternative low power
SOCs and CPUs, such as tablet oriented X86 devices and other RISC CPUs may
be used
as well. The Module power envelope is typically under 6W although designs up to about 15W
are possible.
Two Module sizes are defined: 82mm x 50mm and 82mm x 80mm. The Module PCBs have
314 edge fingers that mate with a low profile 314 pin 0.5mm pitch right angle connector (the
connector is sometimes identified as a 321 pin connector, but 7 pins are lost to the key).
The Modules are used as building blocks for portable and stationary embedded systems.
The core CPU and support circuits, including DRAM, boot flash, power sequencing, CPU
power supplies, GBE and dual channel LVDS display transmitter are concentrated on
the Module. The Modules are used with application specific Carrier Boards that
implement other features such as audio CODECs, touch controllers, wireless devices,
etc. The modular approach allows scalability, fast time to market and upgradability while
still maintaining low costs, low power and small physical size.
