Texas Instruments TMS320F28374DZWTT

Overview

TMS320F28374DZWTT from Texas Instruments is a dual-core 32-bit real-time microcontroller with two 200MHz C28x CPUs, IEEE 754 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 (16 HRPWM), dual CAN, USB 2.0, and 169 GPIOs - deployed in traction inverter motor control and solar power optimizers.

For engineers reviewing the TMS320F28374DZWTT datasheet, TMS320F28374DZWTT pinout, TMS320F28374DZWTT application, or TMS320F28374DZWTT equivalent, key selection criteria include dual-CPU real-time determinism, on-chip analog subsystem resolution (16-bit/1.1MSPS per ADC), HRPWM dead-band support, functional safety certification (ISO 26262 ASIL B), and nFBGA-337 thermal performance at –40°C to 105°C junction.

Technical Context

The TMS320F28374DZWTT implements a tightly coupled dual-C28x architecture where each CPU runs at 200MHz with dedicated FPU, TMU, and VCU-II for trigonometric and complex math acceleration. Each core pairs with an independent 200MHz CLA that executes time-critical control loops (e.g., current regulation) concurrently with main CPU tasks like communication and diagnostics.

Its analog subsystem includes four independent ADCs supporting simultaneous 16-bit differential (1.1MSPS) or 12-bit single-ended (3.5MSPS) conversion, hardware post-processing (offset calibration, windowed compare, DAC-referenced comparators), and integrated SDFM for isolated shunt current sensing - all synchronized to PWM triggers with sub-100ns latency.

FAQ

What is the maximum ADC sampling rate supported by the TMS320F28374DZWTT?

The TMS320F28374DZWTT supports up to 1.1MSPS per ADC in 16-bit differential mode (4.4MSPS system aggregate) and 3.5MSPS per ADC in 12-bit single-ended mode (14MSPS system aggregate). Each of the four ADCs operates independently with hardware-triggered synchronization to PWM events, enabling precise phase-aligned sampling in motor control applications. The TMS320F28374DZWTT achieves this with dedicated sample-and-hold circuits and on-chip post-processing logic.

Does the TMS320F28374DZWTT support functional safety certification for automotive use?

Yes, the TMS320F28374DZWTT is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD, with hardware integrity rated up to ASIL B. It includes safety mechanisms such as ECC-protected flash/RAM, windowed watchdog timers, missing-clock detection, and hardware BIST. While not AEC-Q100 qualified (denoted by -Q1 suffix), its T-grade (–40°C to 105°C) operation and safety documentation support ASIL B system integration in non-safety-critical automotive subsystems. The TMS320F28374DZWTT meets UL 1998 Class 2 and IEC 60730 Class C requirements.

How many high-resolution PWM channels does the TMS320F28374DZWTT provide?

The TMS320F28374DZWTT provides 16 high-resolution PWM (HRPWM) channels - all 8 ePWM modules support high-resolution on both A and B outputs. These deliver <150ps resolution and support dead-band insertion on both standard and HRPWM outputs. This capability is essential for minimizing switching losses in SiC/GaN-based power stages and enabling advanced modulation schemes like three-level NPC inverters. The TMS320F28374DZWTT integrates dedicated HRPWM trip-zone logic for fast fault response.

What communication interfaces are integrated into the TMS320F28374DZWTT?

The TMS320F28374DZWTT integrates dual CAN 2.0B controllers, four SCI/UART ports, three SPI interfaces, two I²C ports, two McBSPs, one USB 2.0 port (with integrated MAC and PHY), and one uPP interface. All CAN, SCI, SPI, I²C, and uPP interfaces are pin-bootable. The USB interface eliminates the need for external transceivers, while the uPP supports high-speed parallel FPGA interfacing. The TMS320F28374DZWTT uses dedicated DMA channels for zero-CPU-overhead data transfer across all serial peripherals.

Is the TMS320F28374DZWTT pin-compatible with other devices in the F2837xD family?

Yes, the TMS320F28374DZWTT in the ZWT (337-ball nFBGA) package is pin-compatible with TMS320F28377DZWTT, TMS320F28379DZWTT, and TMS320F28376DZWTT - sharing identical ball-out, power/ground assignments, and peripheral pin mappings. This allows hardware reuse across performance tiers. However, it is not pin-compatible with PTP (HLQFP) or PZP (HTQFP) variants due to differing package footprints and I/O counts. The TMS320F28374DZWTT maintains full software compatibility within the C2000™ SDK ecosystem.
