Freescale certifies PROFIBUS reference design in Germany
Freescale Semiconductor and TMG TE of Germany have announced certification of a joint Process Field Bus (PROFIBUS) reference design through the authorized ComDeC PI Test Laboratory in Furth, Germany.
The reference design 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 design 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.
The PROFIBUS field bus is typically used for comms in industrial automation equipment.
“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,” said Guenov.
The TWR-P1025 module can also 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.
