Texas Instruments F28388DZWTS

Overview

TMS320F28388DZWTS from Texas Instruments is a dual-CPU real-time microcontroller featuring two 200-MHz C28x DSP cores, a 125-MHz Arm Cortex-M4 Connectivity Manager, 1 MB total flash (512 KB per C28x CPU + 512 KB CM), 216 KB RAM (44 KB local per C28x + 128 KB global shared), and integrated EtherCAT Slave Controller - deployed in servo drive control modules requiring deterministic low-latency motor control and industrial Ethernet connectivity.

For engineers reviewing the TMS320F28388DZWTS datasheet, TMS320F28388DZWTS pinout, TMS320F28388DZWTS application, or TMS320F28388DZWTS equivalent, key selection criteria include dual-core C28x + Cortex-M4 partitioning, 32-channel high-resolution PWM support, CAN FD and MCAN interface allocation, FSI isolation-capable serial throughput, and functional safety certification up to ASIL B / SIL 2.

Technical Context

The TMS320F28388DZWTS implements a tightly coupled heterogeneous architecture: two independent C28x CPUs each with IEEE 754 double-precision FPU, TMU, VCRC, and CLA co-processors execute real-time control loops at 200 MHz, while the Cortex-M4 CM handles protocol stacks (EtherCAT, USB 2.0, Ethernet 1588), security (AES), and system management at 125 MHz - with dedicated memory spaces, IPC-based inter-core communication, and hardware-isolated message RAM for deterministic data exchange.

Its analog subsystem integrates four 16-bit/12-bit ADCs (1.1 MSPS @ 16-bit, 3.5 MSPS @ 12-bit), eight windowed comparators with 12-bit DAC references, three buffered 12-bit DAC outputs, and eight SDFM input channels - all synchronized to the 200-MHz control timing domain for closed-loop precision in power stage feedback.

FAQ

What is the core architecture of the TMS320F28388DZWTS?

The TMS320F28388DZWTS features a heterogeneous dual-core architecture: two independent TMS320C28x 32-bit DSP CPUs running at 200 MHz, each with IEEE 754 double-precision FPU and Trigonometric Math Unit (TMU), plus an Arm Cortex-M4 Connectivity Manager operating at 125 MHz. This enables parallel execution of real-time control algorithms and protocol stacks without resource contention. The TMS320F28388DZWTS uses dedicated memory spaces and hardware IPC for deterministic inter-core communication.

Does the TMS320F28388DZWTS support EtherCAT communication?

Yes, the TMS320F28388DZWTS includes a dedicated hardware EtherCAT Slave Controller (ESC) with dedicated pins (ESC_CLK, ESC_TX0_ENA, ESC_RX0_DV) and integrated frame processing logic. It supports full EtherCAT protocol handling with sub-microsecond jitter and no CPU overhead - unlike software-based implementations. The TMS320F28388DZWTS ESC is compliant with EtherCAT specifications and enables deterministic motion control cycles at 1 kHz in industrial automation systems.

What analog capabilities does the TMS320F28388DZWTS provide for motor control?

The TMS320F28388DZWTS integrates four high-performance ADCs configurable in 16-bit mode (1.1 MSPS) or 12-bit mode (3.5 MSPS), each with a dedicated sample-and-hold and hardware post-processing. It also includes eight windowed comparators with 12-bit DAC references and three 12-bit buffered DAC outputs - enabling precise current sensing, overcurrent protection, and analog feedback in servo and inverter applications. These analog resources are tightly synchronized to the 200-MHz C28x timing domain for minimal latency in closed-loop control.

How is functional safety addressed in the TMS320F28388DZWTS?

The TMS320F28388DZWTS is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD, with hardware-level safety mechanisms including Hardware Built-in Self Test (HWBIST), Embedded Real-time Analysis and Diagnostic (ERAD), Background CRC (BGCRC), dual-clock comparator (DCC), and windowed watchdog timers. Its dual-zone security module (DCSM) isolates trusted code, and memory protection units enforce access control - making the TMS320F28388DZWTS suitable for safety-critical motor drives and power converters requiring systematic and hardware safety integrity.

What package and pin count does the TMS320F28388DZWTS use?

The TMS320F28388DZWTS uses a 337-ball New Fine Pitch Ball Grid Array (nFBGA) package with ZWT suffix, measuring 16 mm × 16 mm with 0.8-mm ball pitch and an exposed thermal pad. It provides 169 general-purpose I/O pins shared across both C28x CPUs and the Cortex-M4 Connectivity Manager - supporting high-density routing for complex motor control and industrial communication interfaces. The TMS320F28388DZWTS does not offer a QFP variant; only the ZWT nFBGA is specified for this part number.
