3 Description

The TMS320F28003x (F28003x) is a member of the C2000? real-time microcontroller family of scalable, ultralow

latency devices designed for efficiency in power electronics, including but not limited to: high power density,

high switching frequencies, and supporting the use of GaN and SiC technologies.

These include such applications as:

? Motor drives

? Appliances

? Hybrid, electric & powertrain systems

? Solar & EV charging

? Digital power

? Body electronics & lighting

? Test & measurement

The real-time control subsystem is based on TI’s 32-bit C28x DSP core, which provides 120 MHz of signalprocessing

performance for floating- or fixed-point code running from either on-chip flash or SRAM. The

C28x CPU is further boosted by the Floating-Point Unit (FPU), Trigonometric Math Unit (TMU), and VCRC

(Cyclical Redundancy Check) extended instruction sets, speeding up common algorithms key to real-time control

systems.

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 F28003x supports up to 384KB (192KW) of flash memory divided into three 128KB (64KW) banks, which

enable programming and execution in parallel. Up to 69KB (34.5KW) of on-chip SRAM is also available to

supplement the flash memory.

The Live Firmware Update hardware enhancements on F28003x allow fast context switching from the old

firmware to the new firmware to minimize application downtime when updating the device firmware.

High-performance analog blocks are integrated on the F28003x real-time microcontroller (MCU) and are closely

coupled with the processing and PWM units to provide optimal real-time signal chain performance. Sixteen PWM

channels, all supporting frequency-independent resolution modes, enable control of various power stages from a

3-phase inverter to power factor correction and advanced multilevel power topologies.

The inclusion of the Configurable Logic Block (CLB) allows the user to add custom logic and potentially integrate

FPGA-like functions into the C2000 real-time MCU.

Interfacing is supported through various industry-standard communication ports (such as SPI, SCI, I2C, PMBus,

LIN, CAN and CAN FD) and offers multiple pin-muxing options for optimal signal placement. The Fast Serial

Interface (FSI) enables up to 200Mbps of robust communications across an isolation boundary.

New to the C2000 platform is the Host Interface Controller (HIC), a high-throughput interface that allows an

external host to access the resources of the TMS320F28003x directly.
