Texas Instruments TMS320F28374DZWTS

Overview

TMS320F28374DZWTS 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 HRPWM, dual CAN, USB 2.0, and 169 GPIOs - deployed in traction inverter motor control and solar power optimizer systems.

For engineers reviewing the TMS320F28374DZWTS datasheet, TMS320F28374DZWTS pinout, TMS320F28374DZWTS application, or TMS320F28374DZWTS equivalent, key selection criteria include dual-CPU real-time determinism, on-chip analog subsystem precision (16-bit ADC + SDFM + CMPSS), functional safety certification up to ASIL B/SIL 2, and nFBGA-337 thermal performance for high-power converter control.

Technical Context

The TMS320F28374DZWTS implements a tightly coupled dual-C28x architecture with interprocessor communication (IPC) and shared memory, enabling deterministic task partitioning - e.g., one core handling torque/current loops while the other manages communications and diagnostics. Each CPU includes dedicated FPU, TMU, and VCU-II for fast trigonometric and complex math operations critical in motor control transforms.

Its analog subsystem features four independent ADCs with differential/single-ended input modes, hardware post-processing (offset calibration, windowed compare, DAC-referenced comparators), and eight SDFM channels supporting isolated shunt current sensing. The integrated CLB provides FPGA-like logic augmentation for position manager and protection logic without external components.

FAQ

What is the maximum operating junction temperature for the TMS320F28374DZWTS?

The TMS320F28374DZWTS has a rated junction temperature range of –40°C to 105°C (suffix 'T'), verified per TI's SPRS880P datasheet Section 6.4. This specification applies to continuous operation under recommended voltage and thermal conditions, and requires proper PCB thermal design using the ZWT nFBGA's exposed thermal pad.

Does the TMS320F28374DZWTS support functional safety certification out of the box?

Yes, the TMS320F28374DZWTS is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD, with documented hardware integrity and safety manual support. The TMS320F28374DZWTS includes built-in self-test (HWBIST), lockstep-capable peripherals, and error-correcting memory - enabling system-level compliance in motor control and energy conversion applications.

How many ADC modules does the TMS320F28374DZWTS integrate, and what are their key capabilities?

The TMS320F28374DZWTS integrates four independent 16-/12-bit ADCs. Each supports 1.1MSPS (16-bit) or 3.5MSPS (12-bit) conversion rates, differential or single-ended inputs, hardware offset calibration, windowed comparators with 12-bit DAC references, and trigger-to-sample delay capture - enabling precise, low-latency acquisition for multi-phase power converter sensing.

Can the TMS320F28374DZWTS execute code independently on both CPU cores and CLAs simultaneously?

Yes, the TMS320F28374DZWTS supports true parallel execution: both C28x CPUs run at 200MHz with dedicated instruction/data buses, and each CLA operates independently at 200MHz, responding to peripheral triggers without CPU intervention. This architecture allows the TMS320F28374DZWTS to offload time-critical control law execution (e.g., current loop) to CLA while the CPU handles communications and diagnostics.

What package and pin count does the TMS320F28374DZWTS use, and is it pin-compatible with other F2837xD variants?

The TMS320F28374DZWTS uses the 337-ball nFBGA (ZWT) package, 16mm × 16mm. It is pin-compatible with all other ZWT-package F2837xD devices (e.g., TMS320F28377DZWTS, TMS320F28379DZWTS) - sharing identical ball map, power/ground assignments, and peripheral pinouts - enabling hardware reuse across performance tiers.
