C2000™ 32-bit MCU with 100-MHz, FPU, TMU, 128-kb flash, InstaSPIN-FOC, CLB, PGAs, SDFM

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 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 100MHz 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™ microcontrollers

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.
