Working Principle of TMS320F28062PFPS

The TMS320F28062PFPS is based on a 32-bit RISC processor core. This processor core integrates a communications port, memory interface, and peripheral interface. The processor core’s internal architecture includes two 32-bit buses, the program bus and the data bus. The processor core also includes two instruction pipelines and two execution units, allowing for two simultaneous operations.

The processor core can access one internal SRAM unit (16Kbytes), four external SRAM/Flash memory buses, a cache memory unit (16Kbytes), an interrupt controller, a PWM controller, and eight General-Purpose I/O (GPIO) pins.

For multiple motor control applications, the TMS 320F28062PFPS integrates a floating-point unit (FPU) with fast (12-bit) and slow (8-bit) Fourier Transform (FFT) operations, a PID controller, and a fuzzy logic controller. This allows the TMS320F28062PFPS to effectively and accurately control the speed and position of the drive motor.

The TMS320F28062PFPS also includes an 8-bit pulse width modulation (PWM) module for controlling the DC motor drive currents.This module consists of a fast PWM generation engine with high-speed, up to 16-bit resolution PWM generation capability.

The TMS320F28062PFPS also includes a 10-bit and 8-bit 12-bit analog subsystem. This subsystem comprises an A/D converter and a D/A converter with up to 12-bit resolution. It also includes two serial communication ports (SPI, UART, I2C) with support for up to 3 Mbps data rates.

The peripheral interface module (PIM) provides access to the external memory and allows connection to other embedded systems as well as communication with external peripherals. The PIM also provides a debug interface, which allows the TMS320F28062PFPS to connect to a computer for debugging, programming and testing.

In addition to its core functions, the TMS320F28062PFPS also includes safety features such as watchdog timers, an error management module and an error injection unit. The error injection unit can be used to inject faults into the microcontroller to test the system\'s error handling capabilities.

TI has dedicated TMS320F28062PFPS kits and development boards to facilitate and simplify the development of the system. TI also provides hardware and software tools and reference designs to help users develop, debug and test their applications.
