F280039CSPM

The TMS320F28003x (F28003x) is a scalable, ultra-low-latency device series designed to improve the efficiency of power electronics, including but not limited to high power density, high switching frequency, and support for the use of GaN and SiC technologies. These applications include motor drives, appliances, hybrid, electric, and powertrain systems, solar and electric vehicle charging, digital power supplies, body electronics and lighting, and test and measurement. The real-time control subsystem is based on TI's 32-bit C28x DSP core, which can provide 120MHz signal processing performance for floating-point or fixed-point code running from on-chip flash or SRAM. The floating-point unit (FPU), trigonometric function accelerator (TMU), and VCRC (cyclic redundancy check) extended instruction set further enhance the performance of the C28x CPU, thereby accelerating the speed of key common algorithms in real-time control systems. The CLA can offload a large number of common tasks from the main C28x CPU. The CLA is an independent 32-bit floating-point math accelerator that executes in parallel with the CPU. In addition, the CLA has its own dedicated storage resources and can directly access the key peripherals required in typical control systems. Like the main features such as hardware breakpoints and hardware task switching, ANSI C subset support is standard. The F28003x supports up to 384KB (192KW) of flash memory, which is divided into three 128KB (64KW) banks and supports parallel programming and execution. Up to 69KB (34.5KW) of on-chip SRAM can also be used to supplement the flash memory. The real-time firmware update hardware enhancement on the F28003x allows for fast context switching from old firmware to new firmware to minimize application downtime when updating the device firmware. The high-performance analog module is integrated on the F28003x real-time microcontroller (MCU) and is tightly coupled with the processing unit and PWM unit to provide better real-time signal chain performance. All 16 PWM channels support frequency-independent resolution modes, which can control various power stages from three-phase inverters to power factor correction and advanced multi-level power topologies. By adding configurable logic blocks (CLBs), users can add custom logic and integrate FPGA-like functions into the C2000 real-time MCU. Various industry-standard communication ports (such as SPI, SCI, I2C, PMBus, LIN, CAN, and CAN FD) not only support connectivity but also provide multiple pin multiplexing options for excellent signal layout. The fast serial interface (FSI) enables robust communication at up to 200Mbps across isolation boundaries. The C2000 platform has added a host interface controller (HIC), which is a high-throughput interface that allows an external host to directly access the resources of the TMS320F28003x.
