Telit Communications plc has developed a dual-processor GSM/GPRS module that streamlines machine-to-machine (M2M) design for point-of-sale terminals, fleet management systems and automated meter reading applications.

The device is scheduled to be available in Q4, the Italian company's M2M technology arm said.

Dubbed the GE863-PRO3, the quad-band module incorporates two microprocessors based on the ARM9 core and has the same form factor as the compact GE863 BGA mounting technology. The device has integrated memory for software applications, including flash and RAM, and can be programmed in Python and C++ languages.

"With the GE863-PRO3, Telit becomes the first M2M supplier to offer a dual-core concept with independent processors for communication operations and customer real-time applications. This is a crucial advantage over comparable rival products where all applications run on a single CPU," says Dominikus Hierl, president of Telit Wireless Solutions.

The Atmel ARM9 processor enables control of real-time applications that require up to 200 MIPS, so the module is said to be particularly suited to applications requiring high processing power.

The GE863-PRO3 incorporates independent energy management for both CPUs, eliminating the need for additional external memory in the application design.

The module measures just 41mm x 31mm x 3.6mm and is certified for all relevant international markets. Like most of Telit's modules, the part offers remote software update capabilities via the integrated Firmware Over The Air technology.

As well as wireless installation of firmware upgrades, the module has numerous interfaces, including SPI, IIC, SD/MMC and USB, allowing connectivity with peripheral hardware or software such as a camera, keyboard, display, Wi-Fi, Bluetooth or Zigbee.
