2.3.1 TMS320F2800137

The TMS320F280013x is a member of the C2000™ real-time microcontroller family of scalable, ultra-low latency devices designed for efficiency in power electronics applications. The real-time control subsystem is based on TI’s 32-bit C28x DSP core, which provides 120MHz of signal-processing performance for floating- or fixed-point code running from either on-chip flash or Static Random Access Memory (SRAM). The C28x Central Processing Unit (CPU )is further boosted by the Trigonometric Math Unit (TMU) and Cyclical Redundancy Check (VCRC) extended instruction sets, speeding up common algorithms key to real-time control systems. High-performance analog blocks are integrated on the F280013x real-time microcontroller (MCU) and are closely coupled with the processing and PWM units to provide excellent real-time signal chain performance. Fourteen PWM channels, all supporting frequency-independent resolution modes, enable control of various power stages from a three-phase inverter to advanced multilevel power topologies. Interfacing is supported through various industry-standard communication ports (such as Serial Peripheral Interface (SPI), three SCI, UART, I2C, and Controller Area Network (CAN)) and offers multiple pin-multiplexing options for excellent signal placement.
