Freescale and TMG TE Develop First PROFIBUS Interface Certified on Freescale Silicon

Scalable, single-chip solution based on Freescale's popular Tower development environment addresses Layer 2 through 7 processing; includes TMG PROFIBUS stack integrated on Freescale QorIQ P1025 device

BENGALURU, India (Freescale Technology Forum) - Freescale Semiconductor (NYSE: FSL) and TMG TE GmbH have successfully certified their first joint Process Field Bus (PROFIBUS) reference design through the authorized ComDeC PI Test Laboratory in Furth, Germany. The solution integrates the commercial TMG PROFIBUS DP slave protocol stack on Freescale's QorIQ P1025 multicore processor in a Freescale Tower System development platform module, called the TWR-P1025.

The PROFIBUS solution developed for the TWR-P1025 can port to additional QorIQ P1 family processors, including the P1012, P1021, P1016 and P1025 products, as well as Freescale's MPC8309 PowerQUICC processor.

PROFIBUS is a popular field bus (communication) technology commonly used in industrial automation equipment, and is overseen by the PROFIBUS and PROFINET International (PNO/PI) organization. Through better control and online diagnostics, PROFIBUS enables improved asset management for industrial equipment, helping to ensure lower life cycle costs, better quality and higher productivity.

"For the first time, our customers can combine their control application simultaneously with PROFIBUS and/or PROFINET industrial protocols using a single Freescale processor," said Nikolay Guenov, marketing director for Freescale's Networking Processor Division. "This PI-certified reference platform helps reduce chip counts and system costs by connecting the QorIQ P1025 processor directly to an RS-485 transceiver, thereby eliminating the need for separate PROFIBUS ASICs or FPGAs."

The TWR-P1025 module is part of the Freescale Tower System portfolio, a modular development platform consisting of more than 50 controller and peripheral modules, enabling rapid prototyping and tool reuse through reconfigurable hardware. The TWR-P1025 processor module also can operate as a stand-alone single board computer (SBC) development platform.

For PROFIBUS evaluation, the TWR-P1025 controller module is enabled with an executable version of the TMG PROFIBUS software stack, Freescale PROFIBUS layer 2 microcode and applications programming interface (API) source code.

Earlier this year, Freescale demonstrated a PROFIBUS pre-release solution running on the TWR-P1025 module at the 2012 Embedded World conference and at the Freescale Technology Forum-San Antonio.

About the QorIQ and PowerQUICC processors

Freescale's QorIQ P1 processor family includes single- and dual-core options that integrate Power Architecture® cores with a single precision floating point unit, 256 KB L2 cache, a DDR2/3 memory controller with ECC protection, an integrated security engine and extensive connectivity including dual gigabit Ethernet, dual PROFIBUS, dual UART, SPI, I2C, dual PCI Express®, dual USB and GPIO. QorIQ P1 processors are also capable of simultaneously running PROFINET, EtherCAT® and EtherNet/IP(TM) with performance headroom to spare for additional applications.

The MPC8309 PowerQUICC processor delivers 835 DMIPS of core performance at less than 1.6 watts. Critical control applications benefit from its double-precision floating point unit, ECC-protected DRAM memory, and extensive connectivity (dual 10/100 Ethernet, quad CAN, dual UART, SPI, I2C, PCI, USB and GPIO).

Both the MPC8309 and the QorIQ P1 family of processors are included in the Freescale Product Longevity Program, which ensures they will be available for a minimum 10 years from time of launch. For terms and conditions or to obtain a list of available products please see
