●Description
●The Concerto™ family is a multi-core system-on-chip microcontroller with independent communication and real-time control subsystems. The F28M35x is the first series in the Concerto family.
●The communications subsystem is based on the industry-standard 32-bit ARM®Cortex™-M3 CPU and features a wide variety of communication peripherals, including Ethernet 1588, USB OTG with PHY, CAN, UART, SSI, I2C, and an external interface.
●The real-time control subsystem is based on TI’s industry-leading proprietary 32-bit C28x™ Floating-Point CPU and features the most flexible and high-precision control peripherals, including ePWMs with fault protection, and encoders and captures—all as implemented by TI’s C2000™ Piccolo™ and Delfino™ families. In addition, the C28-CPU has been enhanced with the addition of the Viterbi, Complex Math, CRC Unit (VCU) instruction accelerator that implements efficient Viterbi, Complex Arithmetic, 16-bit FFTs and CRC algorithms.
●A high-speed analog subsystem and supplementary RAM memory is shared, along with on-chip voltage regulation and redundant clocking circuitry. Safety considerations also include Error Correction Code (ECC), Parity, and Code Secure Memory, as well as documentation to assist with system-level industrial safety certification.
