Texas Instruments F28384DZWTS

Overview

TMS320F28384DZWTS 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 and GaN/SiC-based motor drives.

For engineers reviewing the TMS320F28384DZWTS datasheet, TMS320F28384DZWTS pinout, TMS320F28384DZWTS application, or TMS320F28384DZWTS equivalent, key selection criteria include dual-core C28x + CM architecture, EtherCAT Slave Controller support, CAN FD capability, 32-channel ePWM with high-resolution mode, and functional safety certification up to ASIL B / SIL 2.

Technical Context

The TMS320F28384DZWTS implements two independent 200-MHz C28x CPUs with IEEE 754 double-precision FPU, TMU, VCRC, and CLA accelerators-each running at 200 MHz with single-precision FPU and autonomous execution. Its dedicated Arm Cortex-M4 Connectivity Manager operates at 125 MHz with 512KB ECC-protected flash and 96KB protected RAM.

Hardware coherency is maintained via IPC (Inter-Processor Communication), MSGRAM, and shared peripherals including EtherCAT Slave Controller, USB 2.0 (MAC+PHY), MCAN (CAN FD), and 10/100 Ethernet MII/RMII. The analog subsystem integrates four 16-bit/12-bit ADCs (1.1 MSPS/3.5 MSPS), eight windowed comparators, and three 12-bit DACs tightly coupled to PWM timing resources.

FAQ

What is the package type and pin count of the TMS320F28384DZWTS?

The TMS320F28384DZWTS uses a 337-ball New Fine Pitch Ball Grid Array (nFBGA) package with a 16 mm × 16 mm body size and 0.8-mm ball pitch. It provides 169 GPIO pins shared across the dual C28x CPUs and Arm Cortex-M4 Connectivity Manager, along with dedicated power, analog, clock, and debug interface terminals. This ZWT package variant is lead-free and RoHS-compliant.

Does the TMS320F28384DZWTS support functional safety standards?

Yes, the TMS320F28384DZWTS 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), dual-clock comparator (DCC), windowed watchdog timer, and memory protection mechanisms. Safety documentation and FMEDA reports are available to support system-level certification efforts.

How does the Connectivity Manager (CM) subsystem interact with the C28x CPUs in the TMS320F28384DZWTS?

The TMS320F28384DZWTS uses Inter-Processor Communication (IPC) registers and Message RAM (24KB shared across C28x CPU1, CPU2, and CM-M4) to coordinate tasks. The CM-M4 runs protocol stacks (EtherCAT, USB, Ethernet) independently, while C28x CPUs handle time-critical PWM, ADC, and control law execution. Shared peripherals like MCAN and USB are accessible by either subsystem via configurable routing, enabling flexible partitioning of real-time and application-layer responsibilities.

What analog capabilities does the TMS320F28384DZWTS provide for closed-loop control?

The TMS320F28384DZWTS integrates four high-speed ADCs - each configurable for 16-bit mode (1.1 MSPS) or 12-bit mode (3.5 MSPS) - with 12 differential or 24 single-ended inputs. Each ADC includes a dedicated sample-and-hold and hardware post-processing. Eight windowed comparators with 12-bit DAC references and three buffered 12-bit DAC outputs enable real-time overcurrent protection, voltage clamping, and feedback conditioning directly in hardware, reducing CPU interrupt load.

Can the TMS320F28384DZWTS be used in automotive applications?

The TMS320F28384DZWTS is rated for –40°C to 125°C junction temperature and supports functional safety requirements up to ASIL B, but it is not AEC-Q100 qualified. For automotive applications requiring AEC-Q100 Grade 1 or Grade 0 qualification, TI offers the pin-compatible TMS320F28384D-Q1 variant. The TMS320F28384DZWTS remains suitable for non-safety-critical automotive subsystems (e.g., cabin HVAC, auxiliary power supplies) where industrial-grade reliability meets design requirements.
