Product details
Overview
TMS320F28386DZWTQR from Texas Instruments is a dual-CPU real-time microcontroller with integrated Connectivity Manager (CM), featuring two 200-MHz C28x DSP cores, one 125-MHz Arm Cortex-M4 core, 1 MB total flash (512 KB per C28x + 512 KB CM), 216 KB RAM, and support for CAN FD, EtherCAT, USB 2.0, and 10/100 Ethernet - deployed in industrial servo drives and solar string inverters.
For engineers reviewing the TMS320F28386DZWTQR datasheet, TMS320F28386DZWTQR pinout, TMS320F28386DZWTQR application, or TMS320F28386DZWTQR equivalent, key selection criteria include dual-core deterministic control latency, CM-offloaded protocol stack execution, functional safety certification (ASIL B / SIL 2), and nFBGA-337 packaging for high-density power electronics layouts.
Technical Context
The TMS320F28386DZWTQR implements a heterogeneous dual-domain architecture: the C28x subsystem handles time-critical PWM generation (32 channels, 16 high-resolution), ADC sampling (4× 16-bit/1.1 MSPS), and CLA-accelerated control law execution, while the independent Arm Cortex-M4 CM subsystem manages connectivity protocols including EtherCAT Slave Controller, MCAN (CAN FD), USB 2.0, and Ethernet 1588.
Memory is partitioned across domains: each C28x CPU has dedicated 512 KB ECC-protected flash and 44 KB local RAM; 128 KB global RAM is shared between CPUs with parity protection; the CM has 512 KB ECC-protected flash and 96 KB protected RAM. Inter-processor communication uses IPC with MSGRAM and hardware mailbox synchronization.
