TMS320F28027PTR 32-bit Real-Time Control Microcontroller

TMS320F28027PTR Overview

The TMS320F28027PTR is a single-chip digital signal microcontroller optimized for real-time control in power-conversion and motor-control systems. It combines a 32?bit fixed-point C28x core with integrated analog and PWM peripherals to reduce external components and speed development. Designers get more real-time determinism with higher control-loop rates and fewer interrupts than many 8? or 16?bit alternatives. For sourcing and component reference, see IC Manufacturer.

TMS320F28027PTR Key Features

• Single 32?bit C28x CPU core for faster integer math and tighter control loops compared to 16?bit controllers.
• On?chip 12?bit ADC with multiple channels to sample current and voltage signals without external converters.
• Three high?resolution ePWM modules to generate synchronized, phase?shifted PWM for multi?phase motor drives and converters.
• Multiple serial interfaces (SPI, I2C, UART) that simplify sensor and communication integration while reducing board count.
• Compact 28?pin package for space?constrained designs while still offering over 20 GPIOs for control and monitoring.
• Industrial temperature rating and 3.3 V operation for compatibility with common industrial power rails and peripherals.

Typical Applications

• Motor control systems where deterministic PWM timing and sub?100 ??s control loops improve torque ripple and efficiency in compact inverters.
• Power?conversion controllers for DC?DC and AC?DC supplies that need integrated ADCs and multiple PWM outputs to lower BOM cost.
• Appliance and HVAC controls requiring precise, real?time control of motors and sensors in a small, industrial?rated package.
• Sensor?fusion and embedded control nodes that combine analog acquisition with serial communication to downstream controllers and displays.

TMS320F28027PTR Advantages vs Typical Alternatives

The device offers a clear performance step up versus many 8? and 16?bit microcontrollers. With a 32?bit core running at 60 MHz, more integer operations complete per cycle and control algorithms execute faster. Integrated ADC and multiple ePWM modules reduce external components and board area compared with discrete ADC?plus?FPGA solutions. The compact 28?pin package supplies more GPIOs and peripherals than similar small packages, making the part a better fit for compact industrial controllers and cost?sensitive designs.
