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.

3.2.1 ATX / AT Power supply mode

When using an ATX power supply, the SMARC module starts after you press the power-on button SW1. The ATX power supply can also be used in AT mode. In this case the module starts when you turn on the power supply. Configure the power supply to ATX or AT mode with Jumper (JP14).

6 Additional Features

6.1 Power Button

The SMARC module performs a power up sequence when you press this button. The power button is connected to the SMARC module’s POWER_BTN# signal.

6.2 Reset Button

When you press this button, the SMARC module and all components connected on the SMARC will perform a hard reset. The reset button is connected to the SMARC module’s RESET_OUT# signal.

6.3 Sleep Button

The SMARC module enters a sleep state when you press this button. The sleep button is connected to the SMARC module’s SLEEP# signal.

6.4 Force Recovery Button

Low on this pin allows non-protected segments of Module boot device to be rewritten / restored from an external USB Host on Module USB0. The Module USB0 operates in Client Mode when Force Recovery function is invoked. Pull high on the Module for SOCs that do not implement a USB based Force Recovery functions, then a low on the Module FORCE_RECOV# pin may invoke the SOC native Force Recovery mode – such as over a Serial Port. For x86 systems this signal may be used to load BIOS defaults.

6.5 LID Button

Pressing the LID button creates a low active signal used by the ACPI operating system to detect a LID switch and to bring the system into either a sleep state or to wake it up again. The LID button is connected to the Qseven® module’s LID_BTN# signal.
