Product details
Overview
TMS320F28374SZWTS from Texas Instruments is a 32-bit floating-point real-time microcontroller with dual 200MHz C28x CPU and CLA subsystems, IEEE 754 FPU, TMU, VCU-II, 512KB flash (ECC-protected), 132KB RAM (parity-protected), and integrated analog peripherals including four 16-/12-bit ADCs (up to 4.4MSPS total), three 12-bit DACs, and 24 ePWM channels - deployed in solar inverters, EV charging power modules, and industrial motor drives.
For engineers reviewing the TMS320F28374SZWTS datasheet, TMS320F28374SZWTS pinout, TMS320F28374SZWTS application, or TMS320F28374SZWTS equivalent, key selection criteria include its 337-ball nFBGA (ZWT) package, –40°C to 125°C junction temperature rating (S-grade), functional safety compliance (IEC 61508 SIL 2, ISO 26262 ASIL B), and support for high-resolution PWM, sigma-delta filtering, and parallel CLA execution.
Technical Context
The TMS320F28374SZWTS implements a dual-core real-time control architecture: one C28x CPU and one independent CLA coprocessor, both operating at 200MHz with IEEE 754 single-precision floating-point support. Its analog subsystem integrates four ADCs configurable in 16-bit (1.1MSPS each) or 12-bit (3.5MSPS each) modes, each with differential/single-ended inputs, S/H, and hardware post-processing including windowed comparators with DAC references.
Control peripherals include 24 ePWM channels (16 with high-resolution capability), six eCAP modules, three eQEP modules, and eight SDFM input channels with dual parallel filters per channel. Communications include two CAN 2.0B modules, four SCI/UARTs, three SPIs, two I²C interfaces, USB 2.0 (MAC+PHY), and a uPP interface - all accessible on the ZWT package's 169 GPIO pins.

Documentation for system-level safety design is provided by Texas Instruments per IEC 61508 and ISO 26262 requirements.
How many high-resolution PWM (HRPWM) channels does TMS320F28374SZWTS provide?
The TMS320F28374SZWTS provides 16 high-resolution PWM (HRPWM) channels - eight modules, each with A and B outputs - enabling sub-nanosecond phase control for SiC and GaN gate drivers. These channels support dead-band insertion, trip-zone protection, and event-triggered synchronization with ADC conversions. This specification is explicitly listed in Table 4-1 of the SPRS881K device comparison document.
Is TMS320F28374SZWTS pin-compatible with other devices in the F2837xS family?
Yes, the TMS320F28374SZWTS is pin-compatible with other ZWT-package variants in the F2837xS family, including TMS320F28377S and TMS320F28379S. All share identical 337-ball nFBGA mechanical layout, power/ground ball assignment, and peripheral pin mapping. However, feature enablement (e.g., number of ADCs, SDFM channels, EMIFs) varies per device - verified in the Device Comparison table (Table 4-1) of SPRS881K.
