Overview
The TMS320F28379DZWTQR is a powerful 32-bit floating-point microcontroller unit (MCU) from Texas Instruments, part of the C2000™ microcontroller family. This device is designed for advanced closed-loop control applications, leveraging a dual-core architecture to significantly enhance system performance. Each core is based on TI's 32-bit C28x CPUs, operating at 200 MHz and featuring an IEEE 754 single-precision Floating-Point Unit (FPU), a Trigonometric Math Unit (TMU), and a Viterbi/Complex Math Unit (VCU-II). The MCU also includes two programmable Control Law Accelerators (CLAs) that can execute code independently of the main CPU, further optimizing real-time control tasks.
