Introduction

The Texas Instruments TMS320F28027FPTT is an embedded microcontroller designed for cost-sensitive applications with an integrated 16-bit system-on-chip (SoC) architecture. This device provides flexibility, integration and performance for many embedded applications, such as industrial motor control, automotive infotainment systems, digital power supplies, industrial automation and white goods. This article will discuss the TMS320F28027FPTT application field and working principles.

Application Field

The TMS320F28027FPTT is a microcontroller that is designed for battery-powered, cost-sensitive embedded applications. It is a low-power SoC containing integrated communications and timing peripherals. The device is suitable for applications such as industrial motor control, digital power supplies, white goods and other embedded systems. The TMS320F28027FPTT contains a system controller, 16-bit timer/counter and three low-power watchdog timers. It supports up to 8 kB Flash with EEPROM emulation, 8051 peripheral controllers, an external memory controller and a communications controller. Additionally, the device has a high-frequency serial communications (HISCI) interface with Synergy E20 transceivers that support CAN, CAN FD, UART, SPI and I2C communications. The on-chip TIM2 timer/counter features an anti-lock braking (ABS) and traction control system (TCS). These features are done using pulse-width modulation (PWM), which allows for accurate control of motor and output devices. The device also supports serial communication peripherals such as I2C, SPI, and UART protocols.

Working Principle

The working principle of the TMS320F28027FPTT is based on an integration of several processors. The device contains an integrated Cortex-M3 processor, a single-cycle 16-bit timer/counter, three low-power watchdog timers and an external memory controller.The Cortex-M3 processor is the core of the TMS320F28027FPTT. It is a 32-bit processor with a maximum clock frequency of 80 MHz. The processor contains four working modes: Supervisor, User, System and Abort, which are used to limit access to specific peripherals and memories depending on the application requirements.The device also contains a single-cycle 16-bit timer/counter that can be used for time-based functions such as timer interrupts or for pulse-width modulation (PWM). Additionally, the device has three low-power watchdog timers that are used to monitor the processor health and guarantee its quick recovery from potential errors.The external memory controller supports up to 8 kB Flash with EEPROM emulation. This memory can be used to store the application code and the data necessary for the system operation. In addition to Flash, external memories can also be connected, such as serial and parallel memories.The device also has a high-frequency serial communications (HISCI) interface with Synergy E20 transceivers. This allows the device to communicate with other devices through CAN, CAN FD, UART, SPI and I2C protocols.

Conclusion

The TMS320F28027FPTT is an embedded microcontroller designed for cost-sensitive battery-powered applications. It is a low-power SoC with integrated communications and timing peripherals. It contains an integrated Cortex-M3 processor, a single-cycle 16-bit timer/counter, three low-power watchdog timers and a high-frequency serial communications (HISCI) interface with Synergy E20 transceivers. The device also features anti-lock braking (ABS) and traction control system (TCS) as well as support for external memories such as Flash and serial memories.
