Texas Instruments F28388DZWTSR

Overview

F28388DZWTSR from Texas Instruments is a dual-CPU real-time microcontroller featuring two 200-MHz TMS320C28x DSP cores, IEEE 754 double-precision FPU, and an independent 125-MHz Arm Cortex-M4 Connectivity Manager (CM). It integrates 1 MB flash (512 KB per C28x CPU + 512 KB CM), 216 KB RAM, and supports EtherCAT Slave, CAN FD, USB 2.0, and 10/100 Ethernet - deployed in industrial servo drives and solar string inverters.

For engineers reviewing the F28388DZWTSR datasheet, F28388DZWTSR pinout, F28388DZWTSR application, or F28388DZWTSR equivalent, key selection criteria include dual-core deterministic control latency, CM-offloaded protocol stack execution, functional safety certification (ISO 26262 ASIL B / IEC 61508 SIL 2), and nFBGA-337 packaging for high-density power electronics layouts.

Technical Context

The F28388DZWTSR implements a heterogeneous dual-subsystem architecture: the C28x subsystem executes time-critical PWM, ADC, and motor control loops at 200 MHz with CLA-accelerated math, while the Cortex-M4 CM handles connectivity protocols (EtherCAT, USB, Ethernet) and security functions (AES, GCRC) independently. Both subsystems share memory via IPC and MSGRAM with hardware-enforced isolation.

Its analog subsystem includes four 16-bit/12-bit ADCs (1.1 MSPS @ 16-bit, 3.5 MSPS @ 12-bit), eight windowed comparators with DAC references, and three buffered 12-bit DACs - tightly synchronized to 32 ePWM channels (16 high-resolution) and seven eCAP modules (two with HRCAP) for precision power stage timing and feedback.

FAQ

What is the core architecture of the F28388DZWTSR?

The F28388DZWTSR features a heterogeneous dual-core architecture: two independent 200-MHz TMS320C28x DSP cores with IEEE 754 double-precision FPU and Trigonometric Math Unit (TMU), plus a dedicated 125-MHz Arm Cortex-M4 Connectivity Manager (CM) with 512 KB flash and 96 KB RAM. This separation allows concurrent real-time control and protocol handling without resource contention - a defining capability of the F28388DZWTSR.

Does the F28388DZWTSR support functional safety certification?

Yes, the F28388DZWTSR is ISO 26262 ASIL B certified by TÜV SÜD and IEC 61508 SIL 2 certified for functional safety applications. It includes hardware safety mechanisms such as Hardware Built-in Self Test (HWBIST), Embedded Real-time Analysis and Diagnostic (ERAD), windowed watchdog timers, and dual-clock comparators - all documented to support system-level safety certification efforts for the F28388DZWTSR.

What package type does the F28388DZWTSR use?

The F28388DZWTSR 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. It is lead-free and RoHS-compliant, optimized for high-density PCB layouts in power electronics applications requiring thermal and signal integrity - the official package designation for the F28388DZWTSR.

How many ADCs does the F28388DZWTSR integrate, and what are their key specs?

The F28388DZWTSR integrates four simultaneous-sampling ADCs, each configurable in 16-bit mode (1.1 MSPS) or 12-bit mode (3.5 MSPS), with 12 differential or 24 single-ended inputs per ADC. Each includes a dedicated sample-and-hold and hardware post-processing (averaging, windowing). These ADCs are synchronized to the F28388DZWTSR's PWM subsystem for precise current/voltage feedback in motor and power control applications.

What communication interfaces are supported by the F28388DZWTSR's Connectivity Manager?

The F28388DZWTSR's Connectivity Manager (CM) supports 10/100 Ethernet MII/RMII with IEEE 1588 timestamping, EtherCAT Slave Controller (dual-port), USB 2.0 (MAC + PHY), CM-UART, CM-I²C, SSI, and Generic CRC (GCRC). It also enables CM-C28x shared interfaces including two CAN FD modules - all operating independently of the C28x cores to ensure deterministic real-time control remains unaffected by connectivity traffic on the F28388DZWTSR.
