Ny avancerede kommunikationsfaciliteter i C2000 MCU'er

Texas Instruments præsenterer C2000 MCU'er, der understøtter udvidet konnektivitet som EtherCAT, Ethernet og CAN inklusiv CAN FD (in english).

Texas Instruments has introduced new communications capabilities on its C2000 microcontrollers (MCUs). C2000 F2838x 32-bit MCUs enable designers to use a single chip to implement connectivity, including EtherCAT, Ethernet and Controller Area Network with Flexible Data Rate (CAN FD), in AC servo drives and other industrial systems.

Systems with communication interfaces often require an external application-specific integrated circuit (ASIC) or dedicated host control microprocessor, which limits the flexibility of the design architecture, adds complexity and takes up space on the board. The new C2000 F2838x MCUs do not require an external ASIC, therefore reducing overall solution size and bill of materials.


By integrating three industrial communication protocols, the F2838x MCUs give designers the ability to tailor one MCU to the unique needs of each system. A key component in achieving this is a new connectivity manager, an Arm Cortex-M4-based subsystem, which offloads processing-intensive communications and optimizes connectivity. In addition to these capabilities, C2000 F2838x MCUs offer enhanced real-time control performance and higher flexibility than previous C2000 series MCUs.

Key features and benefits of the C2000 F2838x series includes:

• Integrates EtherCAT, Ethernet and CAN FD: For electrically isolated architectures, the new MCUs use a fast serial interface with eight receiving channels to facilitate chip-to-chip communication at up to 200 Mbps using minimal pins. Designers can build on this high level of integration in CAN FD designs and quickly increase the number of available CAN FD ports by pairing the F2838x with a TI system basis chip (SBC), such as the TCAN4550 SBC with integrated CAN FD controller and transceiver.

• Maximizes real-time control performance: With a 64-bit floating-point unit and fast integer division hardware, the C28x central processing unit-based control allows for differentiated capability and high-precision designs. For servo drive applications, the fast current-loop technology processes field-oriented control in less than 500 ns to enable more precise position control.

• Flexible integration of sensing facilitates real-time control: The C2000 F2838x series also integrates a single-ended 16-bit analog-to-digital converter, which doubles the number of available channels compared to previous C2000 MCUs to minimize external components, minimize system latency and maximize control-loop accuracy. An expanded configurable logic block enables designers to customize peripherals and removes or reduces the need for a field-programmable gate array.
