Product details
Overview
TMS320F28376SZWTT from Texas Instruments is a 32-bit floating-point real-time microcontroller with dual 200MHz C28x CPU and CLA coprocessor, IEEE 754 FPU, TMU, VCU-II, 1MB flash (ECC-protected), 164KB RAM (ECC/parity-protected), and integrated analog subsystem including four 16-/12-bit ADCs (up to 4.4MSPS total), three 12-bit DACs, and eight SDFM channels - deployed in EV traction inverters and solar power optimizers.
For engineers reviewing the TMS320F28376SZWTT datasheet, TMS320F28376SZWTT pinout, TMS320F28376SZWTT application, or TMS320F28376SZWTT equivalent, key selection considerations include its nFBGA-337 package, –40°C to 105°C temperature grade (T suffix), functional safety compliance up to ASIL B/SIL 2, and support for high-resolution PWM (16 HRPWM channels) and dual EMIF interfaces for external memory expansion.
Technical Context
The TMS320F28376SZWTT implements a single-CPU + single-CLA architecture (vs. dual-CPU F2837xD), both running at 200MHz with independent IEEE 754 floating-point execution. Its analog subsystem integrates four ADCs with differential/single-ended modes, hardware post-processing (offset calibration, windowed compare), and SDFM modules for isolated current sensing via sigma-delta modulators.
System-level features include two ISO 11898-1/CAN 2.0B-compliant controllers, USB 2.0 (MAC+PHY), three SPI ports, four SCI/UARTs, two I²C interfaces, and configurable logic blocks (CLB) augmenting ePWM and capture peripheral functionality - all coordinated by an expanded ePIE interrupt controller supporting up to 192 vectors.

FAQ
What is the operating temperature range for the TMS320F28376SZWTT?
The TMS320F28376SZWTT is rated for a junction temperature range of –40°C to 105°C (T grade), validated per TI's recommended operating conditions. This makes it suitable for industrial motor drives and solar inverters where ambient temperatures remain below 85°C with adequate PCB thermal design and airflow. The 'T' suffix explicitly denotes this commercial-extended temperature specification.
Does the TMS320F28376SZWTT support CAN FD or only classical CAN 2.0B?
The TMS320F28376SZWTT integrates two D_CAN modules compliant with ISO 11898-1 and supporting CAN 2.0B protocol only - it does not implement CAN FD physical layer or protocol enhancements. For CAN FD requirements, designers must add external transceivers and manage protocol stack in software or select a newer C2000 device such as TMS320F280039C.
How many high-resolution PWM (HRPWM) channels does the TMS320F28376SZWTT provide?
The TMS320F28376SZWTT provides 16 HRPWM channels - eight modules, each with A and B output, all supporting 150ps resolution adjustment. These are distributed across ePWM1–ePWM8 and enable precise dead-time control critical for SiC and GaN-based power stages in high-frequency inverters.
Is the TMS320F28376SZWTT pin-compatible with the TMS320F28377S in the ZWT package?
Yes, the TMS320F28376SZWTT and TMS320F28377S share identical pinout, ball assignment, and package dimensions in the 337-ball nFBGA (ZWT) variant. Both support the same GPIO multiplexing, peripheral mapping, and power/ground ball layout - enabling drop-in replacement where flash, RAM, and CLB requirements align.
What development tools are officially supported for the TMS320F28376SZWTT?
Texas Instruments officially supports the TMS320F28376SZWTT with C2000Ware software framework, MotorControl SDK, DigitalPower SDK, Code Composer Studio v12+, and the LAUNCHXL-F28379D LaunchPad development kit. Debugging uses XDS110 JTAG interface, and hardware evaluation leverages the TMDSCNCD28379D controlCARD with isolated probes and power stage.
