F280049CPMS

Piccolo TMS320F28004x (F28004x) is a powerful 32-bit floating-point microcontroller unit (MCU) that allows designers to integrate critical control peripherals, differential analog, and non-volatile memory on a single device. Real-time control subsystem is based on TI's 32-bit C28x CPU, which provides 100MHz signal processing performance. The performance of the C28x CPU is further enhanced by the new TMU extended instruction set and VCU-I extended instruction set. The TMU extended instruction set can quickly execute algorithms containing trigonometric operations common in transformation and torque loop calculations, and the VCU-I extended instruction set can reduce the latency of complex mathematical operations common in coding applications. CLA allows a large number of common tasks to be offloaded from the C28x CPU. CLA is an independent 32-bit floating-point math accelerator that executes in parallel with the CPU. In addition, CLA has its own dedicated storage resources, which can directly access the main peripherals required in typical control systems. ANSI C subset support is standard, as are key features such as hardware breakpoints and hardware task switching. F28004x supports up to 256KB (128KW) of flash memory, which is divided into two 128KB (64KW) banks to support parallel programming and execution. In addition, up to 100KB (50KW) of on-chip SRAM is provided in 4KB (2KW) and 16KB (8KW) blocks for efficient system partitioning. Flash ECC, SRAM ECC/parity, and dual-region security are also supported. High-performance analog blocks are integrated on the F28004x MCU to further support system integration. Three independent 12-bit ADCs can accurately and efficiently manage multiple analog signals, ultimately improving system throughput. Seven PGAs on the analog front end can achieve on-chip voltage regulation before conversion. Seven analog comparator modules can continuously monitor the input voltage level for trip conditions. TMS 320C2000 devices include industry-leading control peripherals (with frequency-independent ePWM/HRPWM and eCAP), allowing for first-class control of the system. The built-in 4-channel SDFM allows seamless integration of oversampling Σ-Δ modulators across isolation layers. Connectivity is supported through various industry-standard communication ports (such as SPI, SCI, I2C, LIN, and CAN), and multiple multiplexing is provided to achieve optimal signal placement in various applications. A fully compliant PMBus is new to the C2000 platform. In addition, FSI leads the industry in achieving high-speed and reliable communication to complement the rich set of peripherals embedded in the device. The specially implemented device model TMS320F28004xC allows access to a configurable logic block (CLB) for additional connectivity features and also allows access to a secure ROM that contains libraries for supporting InstaSPIN-FOC. For more information, see the device comparison. The embedded real-time analysis and diagnostic (ERAD) module enhances the device's debugging and system analysis capabilities by providing additional hardware breakpoints and counters for analysis.
