The TQMa31 with an i.MX31 processor by Freescale is predestined for applications that demand high computing power and superior graphics performance. The muscular performance is provided by the ARM11 core with up to 532 MHz and a vector floating point unit.

The mini-module possess an integrated graphics controller (with a 3D accelerator up to VGA) and an MPEG-4 encoder, and its power consumption is surprisingly low (approximately 3.3 Watts at 532 MHz).

Equipped with memory up to 256 MB DDR SDRAM and up to 1 GB NAND Flash, additional external memories, for example to integrate a file system, are unnecessary. Up to 128 MB NOR Flash for program code such as the bootloader and operating system are also available. With an additional memory interface for CF cards via ATA, the module has more than enough memory reserves for nearly any conceivable application.

In addition to the high processing performance, the TQMa31 also has extensive communication and expansion interfaces: USB OTG interfaces (High-speed), CAN-2.0B interfaces, I²C, SPI and serial interfaces.

An outstanding unique feature is the Altera FPGA integrated in the module with free resources for many applications such as signal processing.

Hence flexible expansions such as a second Ethernet or CAN interface or additional GPIOs are possible.

The I/O level conversion by the FPGA eliminates the need for components that are otherwise necessary since level conversion is no longer necessary on the mainboard.

Either Linux or Windows Embedded CE is available as an operating system for the module. The TQMa31 is the only module that offers Windows CE on a hardware platform for an extended temperature range.

Like all TQ modules, the TQMa31 was designed for hard use in an industrial environment: The small 75 x 60 mm module has exclusively long-lasting components tailored to industrial requirements that are available in an extended temperature range of -30°C to +85°C*. Particular care was given to finding the right connection system: The mezzanine connectors (480 pins) with a grid of 0.8 mm. Factors that ensure years of reliable operation in the terminal device.

Other additional core features are long-term availability and scalability of memory expansion.

For fast and easy startup, TQ Components offers an evaluation board. The plug and play principle can be used during software development when the actual target hardware is not available. This enables products to be launched more quickly and economically.
