The TMS320F28021DAS (Digital Analogue Signal) microcontroller is a modern, low power, embedded microcontroller and versatile digital signal processor (DSP) blend by Texas Instruments. It is an integrated circuit and has a range of applications in both industrial and consumer systems. The combination of the two technologies of a microcontroller and a DSP enhances the performance of the products and adds great value to the system designs.

Overview of TMS320F28021DAS

The TMS320F28021DAS is a 32-bit microcontroller and digital signal processor (DSP) integrated in a single, char- tured design. It is based on the TMS320F2802x architecture and has an optimized core architecture and simplified instruction set. The F2802x processor combines a highlyconfigurable RISC controller corewith a floating-point digital signal processor core to make it an ideal solution for real-time embedded control and signal processing applications. The F2802x core consists of a floating- point DSP core, a segmented RISC microcontroller core, an integrated on-chip memory controller, and peripheral support for PWM, CAN, SPI, I2C, I2S and UART.

TMS320F28021DAS Application Field

The TMS320F28021DAS has several applications in automotive, industrial, consumer, and communication markets. Its low-power rating combined with its powerful dual-core architecture has made it a popular choice for embedded applications. It is used in automotive engine and motor control systems, solar inverters, motor drives, power train systems, consumer appliances, and monitoring and measurement systems.

The F2802x devices have also been designed for a variety of industrial and consumer-driven applications, including Smart Meters, Gateways and Nodes for IoT, Portable Medical Instruments, Motor and Powertrain Control, Set Top Boxes, Air Conditioners, White Goods, Telecommunications, Industrial Automation and Process Control, and Home Automation. The TMS320F28021DAS microcontroller is also used in healthcare and medical systems, industrial drives, automotive instrumentation control systems, industrial machinery maintenance, and many more applications.

TMS320F28021DAS Working Principle

The TMS320F28021DAS operates with a two-stage pipeline consisting of an instruction fetch stage and an execution stage. Instructions are fetched from the program memory and either decoded and executed or data is fetched from the data memory. This two-stage pipeline allows the processor to execute instructions and data simultaneously. The F2802x core contains two separate instruction and data memory systems which are connected to an internal data bus and an instruction bus respectively. These two buses are connected to the two memory systems which are further connected to the RISC and the DSP cores.

The F2802x core also contains DMA logic that can transfer data between on-chip peripheral functions such as PWM, SPI, I2C, etc., memories such as SRAM, Flash, and external memories such as SRAM and SDRAM. This core has been designed to reduce the processor overhead in the data transfer across peripheral to memory and vice versa.

The F2802x Scratchpad memory consists of eight byte-addressable memory sections, local and global. These sections are used for scratchpad data storage and data manipulation and can be accessed directly from both the DSP and the RISC cores. The core also contains an integrated system timer unit which can be configured to generate periodic interrupts to the RISC core.

The F2802x processor core also supports special instructions to enhance the speed of calculations and data processing operations. These instructions provide special functions including SIMD packing and unpacking, conversion, scaling, and divide operations. These functions can be used to streamline the execution of complex software routines.

Conclusion

The TMS320F28021DAS microcontroller has become an ideal choice for embedded applications due to its low-power rating and powerful dual-core architecture. This processor offers enhanced performance and simplified instruction set as well as integration of peripheral support for PWM, CAN, SPI, I2C, I2S and UART. It offers multiple application areas such as automotive, industrial, consumer, and communication systems, making it a popular choice for embedded development. Its scratchpad memory sections and special instructions further help streamline the execution of complex software routines.
