Product details
Overview
TMS320F28374DPTPT 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 176-pin HLQFP package - deployed in EV traction inverters and solar power optimizers.
For engineers reviewing the TMS320F28374DPTPT datasheet, TMS320F28374DPTPT pinout, TMS320F28374DPTPT application, or TMS320F28374DPTPT equivalent, key selection criteria include dual-CPU deterministic latency, CLA offload capability for torque loop execution, ADC sampling rate vs. channel count trade-offs, HRPWM dead-band resolution, and functional safety certification scope (ASIL B/SIL 2).
Technical Context
The TMS320F28374DPTPT implements a tightly coupled dual-C28x architecture with interprocessor communication (IPC) and shared memory, enabling synchronized control of motor current and position loops across CPU1 and CPU2. Each core includes dedicated 2K×16 D0/D1 RAM, 6×2K×16 local shared RAM, and access to 128KB global shared RAM.
Its analog subsystem features four independent ADCs supporting simultaneous 16-bit (1.1MSPS each) or 12-bit (3.5MSPS each) conversion modes with differential/single-ended inputs, hardware post-processing (offset calibration, windowed compare), and integrated 3×12-bit DAC outputs - all coordinated via the SDFM and CMPSS modules for isolated shunt current sensing and overcurrent protection.

FAQ
What is the maximum ADC sampling rate supported by the TMS320F28374DPTPT in 12-bit mode?
The TMS320F28374DPTPT supports up to 3.5MSPS per ADC in 12-bit mode, delivering a total system throughput of 14MSPS across its four independent ADCs. This mode uses single-ended inputs and supports up to 24 external channels per ADC. The specification is confirmed in the device comparison table and Section 6.10 of the SPRS880P datasheet.
Does the TMS320F28374DPTPT support functional safety certification for automotive use?
No, the TMS320F28374DPTPT is rated for industrial temperature range (–40°C to 105°C) and certified to ISO 26262 ASIL B and IEC 61508 SIL 2 for functional safety - but it is not AEC-Q100 qualified. For automotive applications, TI offers the pin-compatible TMS320F28374D-Q1 variant, which meets AEC-Q100 Grade 1 requirements.
How many high-resolution PWM channels does the TMS320F28374DPTPT provide, and what is their resolution capability?
The TMS320F28374DPTPT provides 16 high-resolution PWM (HRPWM) channels - eight modules with A/B channel pairs. Each HRPWM channel achieves ≤150ps time resolution via digital fine-tuning, enabling precise dead-band control and sub-nanosecond edge placement critical for GaN/SiC gate drivers.
Is the TMS320F28374DPTPT pin-compatible with other devices in the F2837xD family?
Yes, the TMS320F28374DPTPT in the 176-pin PTP (HLQFP) package is pin-compatible with TMS320F28375DPTPT, TMS320F28377DPTPT, and TMS320F28379DPTPT. All share identical pin assignments, power sequencing, and peripheral signal mapping - allowing hardware reuse across performance tiers.
