描述 Description

The Piccolo™ TMS320F28004x (F28004x) is a powerful32-bit floating-point microcontroller unit (MCU) that lets designers incorporate crucial controlperipherals, differentiated analog, and nonvolatile memory on a single device.
The real-time control subsystem is based on TI’s 32-bit C28x CPU, which provides100 MHz of signal processing performance. The C28x CPU is further boosted by the newTMU extended instruction set, which enables fast execution of algorithms with trigonometricoperations commonly found in transforms and torque loop calculations; and the VCU-I extendedinstruction set, which reduces the latency for complex math operations commonly found in encodedapplications.
The CLA allows significant offloading of common tasks from the main C28x CPU. The CLAis 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 keyperipherals that are required in a typical control system. Support of a subset of ANSI C isstandard, 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 isalso 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 enablesystem consolidation. Three separate 12-bit ADCs provide precise and efficient management ofmultiple analog signals, which ultimately boosts system throughput. Seven PGAs on the analog frontend enable on-chip voltage scaling before conversion. Seven analog comparator modules providecontinuous monitoring of input voltage levels for trip conditions.
The TMS320C2000™ devices contain industry-leadingcontrol peripherals with frequency-independent ePWM/HRPWM and eCAP allow for a best-in-class levelof control to the system. The built-in 4-channel SDFM allows for seamless integration of anoversampling sigma-delta modulator across an isolation barrier.
Connectivity is supported through various industry-standard communication ports (suchas SPI, SCI, I2C, LIN, and CAN) and offers multiple muxing options for optimal signal placement ina variety of applications. New to the C2000™ platform is the fullycompliant PMBus. Additionally, in an industry first, the FSI enables high-speed, robustcommunication to complement the rich set of peripherals that are embedded in the device.
A specially enabled device variant, TMS320F28004xC, allows access to the ConfigurableLogic Block (CLB) for additional interfacing features and allows access to the secure ROM, whichincludes a library to enable InstaSPIN-FOC™. See Device Comparison for more information.
The Embedded Real-Time Analysis and Diagnostic (ERAD) module enhances the debug andsystem analysis capabilities of the device by providing additional hardware breakpoints andcounters for profiling.
