Overview

The TMS320F28069 is a high-performance 90MHz 32-bit microcontroller from the C2000 Piccolo family, featuring an integrated Floating-Point Unit (FPU) and a Viterbi, Complex Math, and CRC Unit (VCU). It is designed to handle complex control algorithms with its 256KB Flash and 100KB RAM, making it a robust choice for real-time control applications that require high-precision math and efficient interrupt processing.

Why Choose This Part

This MCU provides native single-precision floating-point support and a Control Law Accelerator (CLA) that executes code independently of the main CPU, significantly reducing latency. Its Harvard bus architecture and atomic operations ensure high-speed data throughput and reliable real-time performance in demanding industrial environments.

Applications

Digital Motor Control
Leverages the C28x core and FPU to execute sensorless field-oriented control (FOC) and high-frequency PWM generation.
Solar Inverters
Utilizes high-resolution PWMs and the 12-bit ADC for precise power conversion and maximum power point tracking (MPPT).
Digital Power Supplies
Handles complex compensation loops in switched-mode power supplies (SMPS) using the DMA and fast interrupt response.
Electric Vehicle Charging
Manages power factor correction (PFC) and communication via the integrated CANbus interface.
