Product details
Overview
TMS320F28374SPTPS from Texas Instruments is a 32-bit floating-point real-time microcontroller featuring a 200MHz C28x CPU, IEEE 754 FPU, Trigonometric Math Unit (TMU), and Viterbi/Complex Math Unit (VCU-II); includes one CLA coprocessor running at 200MHz, 512KB flash (ECC-protected), 132KB RAM (parity-protected), four 16-/12-bit ADCs (up to 4.4MSPS system throughput), 24 ePWM channels with 16 HRPWM outputs, dual CAN modules, USB 2.0 (MAC+PHY), and operates from –40°C to 125°C junction temperature - deployed in solar inverters and EV on-board chargers.
For engineers reviewing the TMS320F28374SPTPS datasheet, TMS320F28374SPTPS pinout, TMS320F28374SPTPS application, or TMS320F28374SPTPS equivalent, key selection considerations include its single-CPU/CLA subsystem architecture, 176-pin HLQFP (PTP) package with 97 GPIOs, functional safety compliance up to ASIL B/SIL 2, and support for high-resolution motor control loops requiring deterministic timing and analog signal acquisition.
Technical Context
The TMS320F28374SPTPS implements a single-core C28x CPU + CLA coprocessor architecture - unlike dual-subsystem F2837xD variants - enabling parallel execution of time-critical control law tasks (e.g., current loop updates) on the CLA while the main CPU handles communications, diagnostics, and higher-level supervision. Its analog subsystem integrates four independent ADCs with hardware post-processing (offset calibration, windowed compare, DAC-referenced comparators) and SDFM channels for isolated shunt current sensing.
System-level timing relies on dual zero-pin 10MHz oscillators, on-chip crystal oscillator, and PLL-based clock generation supporting multiple low-power modes with external wakeup. Peripheral interconnect uses a data bus bridge architecture, with GPIO multiplexing managed via input/output X-BARs and configurable logic blocks (CLB) augmenting ePWM, eCAP, and CMPSS functionality for position manager and protection logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | C28x 32-bit fixed/floating-point processor at 200MHz - delivers deterministic real-time control with IEEE 754 FPU, TMU, and VCU-II acceleration for motor torque and power conversion algorithms. |
| Control Law Accelerator (CLA) | Single 32-bit floating-point coprocessor at 200MHz - executes control code independently of main CPU, enabling concurrent high-frequency loop closure (e.g., 20kHz current loop) without CPU scheduling overhead. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VDDIO | Power supply rails | 1.2V core, 3.3V analog, 3.3V I/O domains - require separate filtering and sequencing per TI SPRUHZ7 guidelines to ensure ADC accuracy and digital integrity. |
| VSS, VSSA, VSSOSC | Ground references | Analog (VSSA), oscillator (VSSOSC), and digital (VSS) grounds must be partitioned and joined at single point near thermal pad to minimize noise coupling into sensitive analog paths. |
| X1 / X2 | Crytal oscillator interface | Supports external crystal (1–20MHz) or oscillator input; internal 10MHz zero-pin oscillators provide fallback clock source during crystal startup or failure. |
| GPIO0–GPIO96 | Multiplexed general-purpose I/O | 97 pins with programmable pullup/pulldown, input filtering, and peripheral muxing - enable flexible routing of ePWM, eCAP, SCI, SPI, CAN, and ADC signals per board layout requirements. |

Does the TMS320F28374SPTPS support functional safety certification for automotive use?
Yes, the TMS320F28374SPTPS is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD. It includes hardware safety mechanisms such as ECC on flash, parity on RAM, windowed watchdog timers, and missing-clock detection - making it suitable for automotive traction inverter and charging module applications requiring systematic and random hardware fault mitigation.
How many high-resolution PWM channels does the TMS320F28374SPTPS provide?
The TMS320F28374SPTPS provides 16 high-resolution PWM (HRPWM) channels - eight ePWM modules each offering A and B channel resolution down to ≤150ps. These channels support advanced gate drive features including independent dead-band control, trip-zone fault protection, and phase-shifted modulation essential for SiC/GaN-based inverters.
What package options are available for the TMS320F28374SPTPS?
The TMS320F28374SPTPS is offered exclusively in the 176-pin PowerPAD™ Thermally Enhanced Low-Profile Quad Flatpack (HLQFP) package with PTP suffix, measuring 24mm × 24mm with an exposed thermal pad. This package is distinct from the ZWT (337-ball nFBGA) and PZP (100-pin HTQFP) variants offered in other F2837xS family members.
Is the TMS320F28374SPTPS pin-compatible with other F2837xS devices?
No - the TMS320F28374SPTPS in the PTP package is not pin-compatible with ZWT or PZP variants due to differing pin counts and ball/pad layouts. However, it shares identical signal functionality and register mapping with other F2837xS MCUs, enabling software reuse across the family when migrating between packages or performance tiers.
