PROFIBUS on AM335x and AM1810 Sitara ARM Microprocessors
PROFIBUS is installed in more than 35 million industrial nodes worldwide and is growing at a rate of approximately 10 percent each year. TI first offered integrated PROFIBUS slave functionality in the Sitara AM1810 ARM9 microprocessor. This is now enhanced to include PROFIBUS master, as well and an entirely new generation of Sitara AM335x ARM Cortex-A8 microprocessors with integrated PROFIBUS master and slave. In both AM1810 and AM335x MPUs, the PROFIBUS Link Layer is implemented by the integrated programmable real-time unit (PRU) subsystem that makes a dedicated PROFIBUS ASIC or FPGA unnecessary. The benefits of this integration not only include lower cost but also smaller size, reduced complexity and lower power.
