Concerto Microcontroller


The Concerto family is a multicore system-on-chip microcontroller unit (MCU) with independent communication and real-time control subsystems. The F28M35x family of devices 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, Controller Area Network (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 TMS320C2000™ Piccolo™ and Delfino™ families. In addition, the C28-CPU has been enhanced with the addition of the 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.
