Product details
Overview
TMS320F28376SPTPT from Texas Instruments is a 32-bit floating-point real-time microcontroller with dual 200MHz C28x CPU and CLA coprocessor, 1MB flash (ECC-protected), 164KB RAM (ECC/parity-protected), four 16-/12-bit ADCs (up to 4.4MSPS system throughput), and integrated HRPWM, eCAP, eQEP, SDFM, and CLB peripherals - deployed in solar string inverters, EV on-board chargers, and industrial servo drives.
For engineers reviewing the TMS320F28376SPTPT datasheet, TMS320F28376SPTPT pinout, TMS320F28376SPTPT application, or TMS320F28376SPTPT equivalent, key selection criteria include its -40°C to 125°C junction temperature rating, 176-pin HLQFP (PTP) package with PowerPAD™ thermal enhancement, functional safety compliance up to ASIL B/SIL 2, and support for CAN 2.0B, USB 2.0 (MAC+PHY), and uPP high-speed parallel interface.
Technical Context
The TMS320F28376SPTPT implements a single-CPU subsystem architecture within the F2837xS family - one 200MHz C28x CPU with IEEE 754 FPU, TMU, VCU-II, and one independent 200MHz CLA coprocessor - enabling concurrent execution of control loops and background tasks. It integrates dual-zone security, hardware BIST, and configurable logic blocks (CLB) for position manager augmentation.
Its analog subsystem includes four 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 comparators, DAC-referenced thresholds), and three 12-bit buffered DAC outputs. The control peripheral set delivers 24 ePWM channels (16 HRPWM-capable), six eCAP modules, three eQEP modules, and eight SDFM input channels with dual parallel filters per channel.

FAQ
What is the maximum operating junction temperature for the TMS320F28376SPTPT?
The TMS320F28376SPTPT is rated for a maximum junction temperature of 125°C, indicated by the 'S' suffix in its part number. This rating applies across its full operating voltage range and enables deployment in high-ambient environments such as enclosed solar inverters and under-hood EV charging modules without derating.
Does the TMS320F28376SPTPT support CAN FD or only classical CAN 2.0B?
The TMS320F28376SPTPT supports only classical CAN 2.0B (ISO 11898-1 compliant) via its two D_CAN modules. It does not implement CAN FD protocol features such as variable bit rate or extended data length. For CAN FD applications, designers must select alternative controllers or add external CAN FD transceivers with protocol translation.
How many high-resolution PWM channels does the TMS320F28376SPTPT provide, and what is their timing resolution?
The TMS320F28376SPTPT provides 16 high-resolution PWM (HRPWM) channels across eight ePWM modules, with A/B channel pairs per module. Each HRPWM channel achieves 150ps time resolution through digital fractional period and frequency control - enabling precise dead-time adjustment and phase-shifted modulation in SiC/GaN power stages.
Is the TMS320F28376SPTPT pin-compatible with the TMS320F28379S ZWT package?
No, the TMS320F28376SPTPT uses a 176-pin HLQFP (PTP) package, while the TMS320F28379S uses a 337-ball nFBGA (ZWT) package. They are not physically or electrically pin-compatible. However, the TMS320F28376SPTPT is pin-compatible with other PTP-package F2837xS devices including TMS320F28377SPTPT and TMS320F28375SPTPT.
What development tools are officially supported for the TMS320F28376SPTPT?
Texas Instruments officially supports the TMS320F28376SPTPT with C2000Ware software framework, MotorControl SDK, DigitalPower SDK, Code Generation Tools v23.x+, and CCS v12.x IDE. Hardware tools include the TMDSCNCD28379D controlCARD and LAUNCHXL-F28379D LaunchPad - both compatible via pin-mapped headers despite differing base MCUs.
