            The AMIC110 device is a multiprotocol programmable industrial communications processor providingready-to-use solutions for most industrial Ethernet and fieldbus communications slaves, as well as somemasters. The device is based on the ARM Cortex-A8 processor, peripherals, and industrial interfaceoptions. The device supports high-level operating systems (HLOS). Linux? and TI-RTOS are available freeof charge from TI. Other RTOS are also offered by TI ecosystem partners. The AMIC110 microprocessoris an ideal companion communications chip to the C2000 family of microcontrollers for connected drives.

            The AMIC110 microprocessor contains the subsystems shown in Figure 1 and a brief description ofeach follows:The microprocessor unit (MPU) subsystem is based on the ARM Cortex-A8 processor. The PRU-ICSS isseparate from the ARM core, allowing independent operation and clocking for greater efficiency andflexibility. The PRU-ICSS enables additional peripheral interfaces and real-time protocols such asEtherCAT, PROFINET IRT, EtherNet/IP, PROFIBUS, Ethernet Powerlink, Sercos III, and others.

            Additionally, the programmable nature of the PRU-ICSS, along with its access to pins, events and allsystem-on-chip (SoC) resources, provides flexibility in implementing fast, real-time responses, specializeddata handling operations, custom peripheral interfaces, and in offloading tasks from the other processorcores of SoC.
