Texas Instruments F28384DPTPQR

Overview

TMS320F28384DPTPQR from Texas Instruments is a dual-core C28x real-time microcontroller with integrated Arm Cortex-M4 Connectivity Manager, operating at 200 MHz (C28x) and 125 MHz (CM), featuring 512KB flash per C28x CPU, 96KB CM RAM, and 128KB global shared RAM. It delivers deterministic control for industrial motor drives, solar inverters, and EV on-board chargers via 32 high-resolution PWM channels, four 16-bit ADCs (1.1 MSPS), and EtherCAT/USB 2.0/CAN FD interfaces.

For engineers reviewing the TMS320F28384DPTPQR datasheet, TMS320F28384DPTPQR pinout, TMS320F28384DPTPQR application, or TMS320F28384DPTPQR equivalent, key selection criteria include dual-CPU real-time determinism, CM-based protocol offload (Ethernet 1588, USB, CAN FD), functional safety certification (ISO 26262 ASIL B, IEC 61508 SIL 2), and HLQFP-176 thermal performance in industrial ambient conditions.

Technical Context

The TMS320F28384DPTPQR implements a tightly coupled dual-C28x architecture where each CPU runs independent 200-MHz code with IEEE 754 double-precision FPU, TMU, and CLA acceleration-enabling concurrent execution of high-speed motor control loops and background diagnostics. Its dedicated Connectivity Manager (Arm Cortex-M4 @ 125 MHz) handles Ethernet 1588, USB 2.0, and CAN FD traffic without burdening C28x cores.

Hardware-level isolation is enforced via dual-zone security (DCSM), ERAD debug trace, and BGCRC memory integrity checking across 512KB C28x flash (ECC-protected), 96KB CM RAM (ECC/parity), and 128KB global RAM (parity-protected). The device supports functional safety development with HWBIST, windowed watchdog timers, and ASIL B/SIL 2 certified hardware blocks.

FAQ

What is the core architecture of the TMS320F28384DPTPQR?

The TMS320F28384DPTPQR features a single 32-bit TMS320C28x CPU core running at 200 MHz, paired with an independent Arm Cortex-M4 Connectivity Manager (CM) operating at 125 MHz. Unlike the dual-C28x F28386D/F28388D variants, the F28384D uses one C28x core to balance cost and performance for mid-tier real-time control applications while retaining full CM functionality including Ethernet 1588, USB 2.0, and CAN FD.

Does the TMS320F28384DPTPQR support functional safety standards?

Yes, the TMS320F28384DPTPQR is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD. It includes hardware safety mechanisms such as Hardware Built-in Self Test (HWBIST), dual-clock comparator (DCC), windowed watchdog timers, and memory protection units-enabling its use in automotive and industrial safety-critical systems when implemented per TI's functional safety documentation.

What package and thermal characteristics does the TMS320F28384DPTPQR have?

The TMS320F28384DPTPQR is offered exclusively in the 176-pin PowerPAD™ HLQFP package (PTP suffix), measuring 24 mm × 24 mm with exposed thermal pad. Its thermal resistance (θ_JA) is 21.2°C/W under JEDEC JESD51-7 conditions, supporting operation up to 125°C ambient temperature with standard PCB copper pour and airflow-making it suitable for convection-cooled industrial motor drive enclosures.

How many ADC channels and what resolution does the TMS320F28384DPTPQR provide?

The TMS320F28384DPTPQR integrates four independent ADC modules, each configurable for 16-bit mode (1.1 MSPS, 12 differential or 24 single-ended inputs) or 12-bit mode (3.5 MSPS, 24 single-ended inputs). Each ADC includes a dedicated sample-and-hold circuit and hardware post-processing for windowed comparisons-enabling precise, low-latency current/voltage sensing in multi-phase inverter topologies without external signal conditioning.

Can the TMS320F28384DPTPQR be used for EtherCAT slave applications?

Yes, the TMS320F28384DPTPQR includes a fully integrated EtherCAT Slave Controller (ESC) within its Connectivity Manager subsystem. This hardware block handles all EtherCAT frame processing, synchronization (DC cycle management), and mailbox communication independently of the C28x CPU-achieving sub-1 µs jitter and eliminating the need for external ESC ASICs in industrial PLC and servo drive designs.
