Product details
Overview
TMS320F28374SPZPS from Texas Instruments is a 32-bit floating-point real-time microcontroller with a 200MHz C28x CPU, IEEE 754 FPU, Trigonometric Math Unit (TMU), and Viterbi/Complex Math Unit (VCU-II), designed for high-precision closed-loop control in industrial motor drives and solar inverters. It integrates one CLA coprocessor (200MHz), 512KB flash (ECC-protected), 132KB RAM (parity-protected), four 16-/12-bit ADCs (up to 4.4MSPS system throughput), and 24 ePWM channels with 16 HRPWM outputs.
For engineers reviewing the TMS320F28374SPZPS datasheet, TMS320F28374SPZPS pinout, TMS320F28374SPZPS application, or TMS320F28374SPZPS equivalent, key selection considerations include its single-CPU/CLA subsystem architecture, S-grade (–40°C to 125°C) junction temperature rating, 176-pin HLQFP package (PTP suffix), dual CAN 2.0B interfaces, USB 2.0 MAC+PHY, and functional safety compliance up to ASIL B/SIL 2.
Technical Context
The TMS320F28374SPZPS implements a single-core C28x CPU + CLA subsystem architecture-distinct from dual-subsystem F2837xD variants-enabling deterministic real-time control with parallel execution of time-critical algorithms on the CLA while the main CPU handles communications and diagnostics. Its analog subsystem includes four independent ADCs supporting simultaneous 16-bit (1.1MSPS each) and 12-bit (3.5MSPS each) conversion modes with hardware post-processing, windowed comparators, and three 12-bit DAC outputs.
System-level integration is enhanced by two EMIFs (ASRAM/SDRAM support), six-channel DMA, 169 GPIOs with input filtering, and communications peripherals including two CAN modules (ISO 11898-1 compliant), three SPI ports, four SCI/UARTs, two I²C interfaces, two McBSPs, and a uPP interface for FPGA co-processing. The device operates at 1.2V core and 3.3V I/O with dual internal 10MHz oscillators and missing-clock detection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28377SPTPS | 1MB flash (vs. 512KB), 164KB RAM (vs. 132KB), same 176-pin PTP package and S-grade temp range. | Higher memory capacity supports larger control algorithms and dual-application firmware (e.g., OBC + DC-DC controller). | Select when firmware complexity exceeds 512KB or additional RAM is required for real-time logging and diagnostics. |
| TMS320F28375SPTPS | Same 512KB flash and 132KB RAM, but only two 16-bit ADCs (vs. four) and reduced GPIO count (97 vs. 169). | Suitable for cost-sensitive, lower-channel-count applications like single-phase UPS or small servo drives. | Select when full ADC count and GPIO flexibility are not required, and BOM cost optimization is prioritized. |
