Industrial MCU Merges Ethernet With CAN Or USB

April 12, 2004

The 150-MHz, 200-MIPS TriCore-based TC1130 MCU built by Infineon Technologies packs motor control with a host of communication options. The MCU has an MMU, a two-cycle hardware context switch, and a four-stage pipeline with a 16-kbyte instruction cache and 4-kbyte data cache. There are 32 kbytes of on-chip program memory and 32 kbytes of data memory plus a 64-kbyte local memory unit.

Two versions of the chip are available, each with a 10/100-Mbit/s Ethernet interface. One has a USB 1.1 host interface. The other has a MultiCAN module capable of supporting four CAN nodes with 64 message buffers. Both chips have two high-speed serial and three async serial interfaces, as well as two high-speed Micro Link Interfaces (MLIs). The Multifunctional General-Purpose Timer Units have three timers plus one-channel and three-channel, 16-bit, capture and compare timers for pulse-width modulation generation.

The TC1130 runs Linux, Nucleus, and OSE. Starter kits are available with GNU and Tasking C compilers.

I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.

I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
