Overview
TMS320F28384SPTPQR from Texas Instruments is a dual-core real-time microcontroller featuring two 200-MHz C28x DSP CPUs, one 125-MHz Arm Cortex-M4 Connectivity Manager (CM), IEEE 754 double-precision FPU, 512KB flash per CPU, and 128KB global shared RAM - designed for high-fidelity motor control and industrial power conversion where deterministic latency and protocol offload are critical.
For engineers reviewing the TMS320F28384SPTPQR datasheet, TMS320F28384SPTPQR pinout, TMS320F28384SPTPQR application, or TMS320F28384SPTPQR equivalent, this device delivers verified dual-CPU real-time control with integrated EtherCAT Slave Controller, CAN FD, USB 2.0, and 10/100 Ethernet - enabling concurrent high-speed motion control and networked system management without external co-processors.
Technical Context
The TMS320F28384SPTPQR implements a tightly coupled heterogeneous architecture: dual C28x CPUs execute time-critical PWM, ADC, and CLA-based control loops at 200 MHz, while the independent Arm Cortex-M4 CM handles connectivity protocols (EtherCAT, CAN FD, USB, Ethernet) and security functions (AES, GCRC) at 125 MHz - with dedicated 512KB ECC-protected flash and 96KB RAM.
Its analog subsystem includes four 16-bit/12-bit ADCs (1.1 MSPS in 16-bit mode, 3.5 MSPS in 12-bit mode), eight windowed comparators with 12-bit DAC references, three buffered 12-bit DAC outputs, and 32 ePWM channels (16 with high-resolution extension) - all synchronized to support multi-axis servo drive and multilevel inverter topologies.
