TMS320F28034PNT Digital Signal Controller: Detailed Overview
The Texas Instruments TMS320F28034PNT is a high-performance 32-bit digital signal controller (DSC) from the C2000™ real-time control series, combining a 60 MHz C28x DSP core with integrated floating-point unit (FPU) and advanced control peripherals. Housed in a 64-pin LQFP package, it operates within a wide temperature range of -40°C to +125°C, making it suitable for industrial and automotive environments. The device features 128 KB of flash memory, 20 KB of RAM, and multiple communication interfaces, including SPI, I²C, CAN, and UART. It supports a supply voltage range of 3.3 V with robust analog integration, such as a 12-bit ADC with 16 channels and 3.55 MSPS sampling rate.
C28x Piccolo™ IC Key Features
The TMS320F28034PNT excels in real-time control applications with its high-resolution pulse-width modulation (HRPWM) modules (150 ps resolution), enabling precise motor and power supply control. Its CLA (Control Law Accelerator) co-processor operates independently of the main CPU, allowing parallel execution of complex algorithms for faster loop closure. Enhanced safety features include parity protection for memory, CRC error checking, and dual-zone code security. The integrated analog comparators, on-chip oscillators, and low-power modes (standby current < 2 µA) further optimize system efficiency and reliability.
Typical Applications
This DSC is widely used in applications demanding real-time processing and high-precision control, such as industrial motor drives (BLDC, PMSM), solar inverters, electric vehicle charging systems, and digital power converters (AC/DC, DC/DC). It also serves in automation equipment (PLC, robotics), medical power supplies, and automotive subsystems like battery management (BMS) and electronic power steering. Its robust analog integration and control peripherals make it ideal for renewable energy systems and factory automation.
Selection Advantages
The TMS320F28034PNT outperforms competitors with its unique blend of DSP performance, analog integration, and real-time control capabilities. Compared to general-purpose microcontrollers, its HRPWM and CLA reduce latency by up to 50% in control loops. The on-chip 12-bit ADC and comparators eliminate external components, reducing BOM costs. Compliance with automotive AEC-Q100 standards and TI’s comprehensive software ecosystem (including ControlSUITE™ and C2000Ware) accelerate development. Additionally, its functional safety documentation supports ISO 26262 ASIL-B/C certification, critical for automotive and industrial safety-critical designs.
