1.5 Interface

An additional block that, while not typically associated with the real-time control loop of the system, is almost always needed from a system integration point of view. Good integration of the interface block with the CPU is essential to avoid high overhead that could impact the control loop. From serial data streams to multi-channel inputs, as well as industry standard options to proprietary formats, the interface sub-system supports a wide array of communications options.

  • Controller Area Network (CAN) – The CAN module supports the Bosch™ CAN protocol standard.
  • External Memory InterFace (EMIF) – Parallel data bus typically used to support connections to SDRAM as well as wide bus peripherals.
  • EtherCAT Slave Controller (EtherCAT) – This module allows for the C2000 MCU to act as a slave node in an EtherCAT network.
  • Ethernet – 10/100 Mbps Ethernet controller and physical interface for external communications across this bus.
  • Fast Serial Interface (FSI) – 2 or 3 line simplex serial data transmit or receive. Designed to meet both the high speed (100Mbps) as well as the variable latency introduced when crossing an isolation boundary.
  • Host Interface Controller (HIC) - Grants ability for other devices to control/interact with the C2000 peripherals
  • Inter-Integrated Circuit (I2C) – Interface/controller for an I2C bus
  • Serial Peripheral Interface (SPI) – Interface/controller for a standard Serial Peripheral Interface bus.
  • Universal Asynchronous Receiver/Transmitter (UART) – Interface/controller for Universal Asynchronous Receiver Transmitter bus
  • Universal Serial Bus (USB) – USB 2.0 MAC and PHY used to interface to standard USB network.

Note: Peripheral counts, as well as features, may vary from device to device. For a complete listing of the number of a peripherals on a device, see the data sheets referenced at the end of each section. For the feature sets supported on a given device, see the C2000 Real-Time Control Peripherals Reference Guide.
