Product details
Overview
TMS320F28375DZWTT from Texas Instruments is a dual-core 32-bit real-time microcontroller featuring two 200MHz C28x CPUs, IEEE 754 single-precision FPU, TMU, VCU-II, and two independent 200MHz CLA coprocessors. It integrates four 16-/12-bit ADCs (up to 4.4MSPS system throughput), 24 ePWM channels with 16 high-resolution outputs, dual CAN, USB 2.0, and 169 GPIOs - deployed in traction inverter motor control and solar power optimizers.
For engineers reviewing the TMS320F28375DZWTT datasheet, TMS320F28375DZWTT pinout, TMS320F28375DZWTT application, or TMS320F28375DZWTT equivalent, key selection criteria include dual-CPU deterministic latency, CLA offload capability for time-critical control loops, 16-bit ADC resolution with hardware post-processing, functional safety certification up to ASIL B/SIL 2, and nFBGA-337 thermal performance in industrial motor drives.
Technical Context
The TMS320F28375DZWTT implements a tightly coupled dual-C28x architecture with interprocessor communication (IPC) and shared memory, enabling coordinated real-time control tasks across CPU1 and CPU2. Each core runs at 200MHz with dedicated FPU, TMU, and VCU-II for fast trigonometric and complex math operations required in field-oriented control (FOC) and sensorless estimation.
Its two CLA coprocessors execute floating-point code independently of the main CPUs, servicing peripheral triggers (e.g., PWM sync, ADC EOC) to reduce CPU load. The analog subsystem includes four ADCs with differential/single-ended modes, SDFM inputs for isolated current sensing, and eight windowed comparators with DAC references for fast overcurrent protection.

FAQ
What is the maximum operating junction temperature for the TMS320F28375DZWTT?
The TMS320F28375DZWTT is rated for –40°C to 105°C junction temperature (T grade). This specification is validated per JEDEC JESD22-A108 and applies to continuous operation under specified thermal conditions with appropriate PCB heat sinking. The nFBGA-337 package supports this rating via its thermal pad and copper pour layout guidelines in TI's SPRUHZ6.
Does the TMS320F28375DZWTT support functional safety certification out of the box?
Yes, the TMS320F28375DZWTT is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD. Its hardware integrity meets ASIL B requirements, and TI provides safety documentation including FMEDA reports, safety manuals, and diagnostic software libraries - enabling system-level compliance in automotive traction inverters and industrial safety drives.
How many ADC channels are accessible on the TMS320F28375DZWTT in the ZWT package?
The TMS320F28375DZWTT in the 337-ball ZWT package provides full access to all 48 ADC input pins: 12 differential (24 pins) or 24 single-ended (24 pins) across its four independent 16-/12-bit ADC modules. Pin assignments are defined in Figure 5-1 through Figure 5-4 of the SPRS880P datasheet.
Can the CLA coprocessors on the TMS320F28375DZWTT execute floating-point code independently of the main CPUs?
Yes, each CLA on the TMS320F28375DZWTT is a fully independent 32-bit floating-point processor running at 200MHz. It responds to peripheral interrupts (e.g., ADC end-of-conversion, PWM timer match), executes user-defined C or assembly code, and communicates with its associated C28x CPU via shared message RAM - enabling true hardware offload of time-critical control tasks.
What development tools are recommended for initial evaluation of the TMS320F28375DZWTT?
TI recommends the LAUNCHXL-F28379D LaunchPad development kit - which is pin-compatible and software-compatible with the TMS320F28375DZWTT - along with C2000Ware v4.0+, Code Generation Tools v23.6.0+, and ControlSuite.
