Texas Instruments F28386DZWTS

Overview

TMS320F28386DZWTS from Texas Instruments is a dual-CPU real-time microcontroller with integrated Arm Cortex-M4 Connectivity Manager, 200 MHz C28x DSP cores, IEEE 754 double-precision FPU, 512KB flash per CPU, and 128KB global shared RAM. It delivers deterministic control for high-frequency power electronics including three-phase inverters, servo drives, and digital power supplies.

For engineers reviewing the TMS320F28386DZWTS datasheet, TMS320F28386DZWTS pinout, TMS320F28386DZWTS application, or TMS320F28386DZWTS equivalent, key selection criteria include dual-core C28x + CM architecture, EtherCAT Slave Controller support, CAN FD interface, 32-channel high-resolution PWM, and functional safety certification up to ASIL B/SIL 2.

Technical Context

The TMS320F28386DZWTS implements two independent 200 MHz C28x CPUs with IEEE 754 double-precision FPU, TMU, and VCRC acceleration, each backed by 512KB ECC-protected flash and 44KB local RAM. A dedicated 125 MHz Arm Cortex-M4 Connectivity Manager handles protocol offload with 512KB ECC flash, 96KB RAM, AES accelerator, and 10/100 Ethernet 1588.

Its analog subsystem includes four 16-bit/12-bit ADCs (1.1 MSPS in 16-bit mode), eight windowed comparators with 12-bit DAC references, and three 12-bit buffered DAC outputs. Control peripherals deliver 32 ePWM channels (16 high-resolution), seven eCAP modules (two with HRCAP), and three eQEP modules - all synchronized across dual C28x domains.

Equivalent & Alternatives

The following parts are listed as comparable options for similar real-time control applications.

Compared with TMS320F28388DZWTS, the TMS320F28386DZWTS offers identical CM capabilities and pin compatibility in ZWT package but reduces C28x resources to one core and removes CLA-ideal for applications needing protocol offload without dual-core control overhead. Versus TMS320F28386SPTP, it adds a second C28x core, EtherCAT, and 72 additional GPIO while retaining the same CM feature set.

FAQ

What is the core architecture of the TMS320F28386DZWTS?

The TMS320F28386DZWTS integrates two independent 200 MHz TMS320C28x 32-bit DSP cores and a 125 MHz Arm Cortex-M4 Connectivity Manager. Each C28x core includes IEEE 754 double-precision FPU, Trigonometric Math Unit (TMU), and VCRC engine. The CM handles Ethernet, USB, CAN FD, and EtherCAT offload. This architecture enables true hardware partitioning between real-time control and connectivity tasks in the TMS320F28386DZWTS.

Does the TMS320F28386DZWTS support functional safety standards?

Yes, the TMS320F28386DZWTS is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD. It includes hardware safety features such as Hardware Built-in Self Test (HWBIST), Embedded Real-time Analysis and Diagnostic (ERAD), Background CRC (BGCRC), dual-zone security, and systematic capability support for ASIL D/SIL 3 system designs - all documented to aid functional safety development for the TMS320F28386DZWTS.

What package and pin count does the TMS320F28386DZWTS use?

The TMS320F28386DZWTS uses a 337-ball New Fine Pitch Ball Grid Array (nFBGA) package with ZWT suffix, measuring 16 mm × 16 mm and featuring 0.5 mm ball pitch and an exposed thermal pad. It provides 169 GPIO pins shared across both C28x CPUs and the Connectivity Manager, supporting flexible signal routing via Input/Output Crossbar (XBAR) matrices.

Which communication protocols are hardware-accelerated in the TMS320F28386DZWTS?

The TMS320F28386DZWTS includes hardware-accelerated EtherCAT Slave Controller, MCAN (CAN FD), 10/100 Ethernet 1588 (MII/RMII), USB 2.0 (MAC + PHY), and Fast Serial Interface (FSI) capable of 200 Mbps. These accelerators offload protocol processing from the C28x CPUs, enabling deterministic real-time control while maintaining high-bandwidth connectivity - a defining capability of the TMS320F28386DZWTS.

Can the TMS320F28386DZWTS replace older C2000 devices like the F28379D?

The TMS320F28386DZWTS is not a pin-compatible replacement for the F28379D due to different package (ZWT vs PTP), increased pin count (169 vs 176), and architectural differences including the integrated Connectivity Manager. While it offers superior performance, EtherCAT, and CAN FD, migration requires PCB redesign and firmware adaptation. The TMS320F28386DZWTS targets next-generation systems where protocol offload and dual-core determinism justify the transition.
