C2000™ 32-bit microcontrollers are optimized for processing, sensing, and actuation to improve closed-loop performance in real-time control applications such as industrial motor drives; solar inverters and digital power; electrical vehicles and transportation; motor control; and sensing and signal processing. The C2000 line includes the Delfino™ Premium Performance family and the Piccolo™ Entry Performance family.
The Piccolo™ TMS320F28004x (F28004x) is a powerful 32-bit floating-point microcontroller unit (MCU) that lets designers incorporate crucial control peripherals, differentiated analog, and nonvolatile memory on a single device.
The real-time control subsystem is based on TI’s 32-bit C28x CPU, which provides 100 MHz of signal processing performance. The C28x CPU is further boosted by the new TMU extended instruction set, which enables fast execution of algorithms with trigonometric operations commonly found in transforms and torque loop calculations; and the VCU-I extended instruction set, which reduces the latency for complex math operations commonly found in encoded applications.
The CLA allows significant offloading 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. Additionally, the CLA has its own dedicated memory resources and it can directly access the key peripherals that are required in a typical control system. Support of a subset of ANSI C is standard, as are key features like hardware breakpoints and hardware task-switching.
The F28004x supports up to 256KB (128KW) of flash memory divided into two 128KB (64KW) banks, which enables programming and execution in parallel. Up to 100KB (50KW) of on-chip SRAM is also available in blocks of 4KB (2KW) and 16KB (8KW) for efficient system partitioning. Flash ECC, SRAM ECC/parity, and dual-zone security are also supported.
High-performance analog blocks are integrated on the F28004x MCU to further enable system consolidation. Three separate 12-bit ADCs provide precise and efficient management of multiple analog signals, which ultimately boosts system throughput. Seven PGAs on the analog front end enable on-chip voltage scaling before conversion. Seven analog comparator modules provide continuous monitoring of input voltage levels for trip conditions.
The TMS320C2000™ devices contain industry-leading control peripherals with frequency-independent ePWM/HRPWM and eCAP allow for a best-in-class level of control to the system. The built-in 4-channel SDFM allows for seamless integration of an oversampling sigma-delta modulator across an isolation barrier.
Connectivity is supported through various industry-standard communication ports (such as SPI, SCI, I2C, LIN, and CAN) and offers multiple muxing options for optimal signal placement in a variety of applications. New to the C2000™ platform is the fully compliant PMBus. Additionally, in an industry first, the FSI enables high-speed, robust communication to complement the rich set of peripherals that are embedded in the device.
A specially enabled device variant, TMS320F28004xC, allows access to the Configurable Logic Block (CLB) for additional interfacing features and allows access to the secure ROM, which includes a library to enable InstaSPIN-FOC™. See Device Comparison for more information.
The Embedded Real-Time Analysis and Diagnostic (ERAD) module enhances the debug and system analysis capabilities of the device by providing additional hardware breakpoints and counters for profiling.
