Product details
Overview
TMS320F28375SPZPS from Texas Instruments is a 32-bit floating-point real-time microcontroller featuring a 200MHz C28x CPU, IEEE 754 FPU, Trigonometric Math Unit (TMU), Viterbi/Complex Math Unit (VCU-II), and a 200MHz CLA coprocessor. It integrates 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, dual CAN, USB 2.0, and SDFM-designed for high-precision motor control in EV traction inverters and solar power converters.
For engineers reviewing the TMS320F28375SPZPS datasheet, TMS320F28375SPZPS pinout, TMS320F28375SPZPS application, or TMS320F28375SPZPS equivalent, key selection considerations include its single-CPU/CLA architecture (vs. dual-core F2837xD), 100-pin HTQFP package with 41 GPIOs, -40°C to 125°C junction temperature rating, functional safety compliance (IEC 61508 SIL 2, ISO 26262 ASIL B), and support for isolated current sensing via SDFM + sigma-delta modulators.
Technical Context
The TMS320F28375SPZPS implements a deterministic real-time control subsystem centered on a single C28x CPU core running at 200MHz with hardware-accelerated floating-point math (FPU, TMU, VCU-II) and an independent CLA coprocessor also operating at 200MHz. Its analog subsystem includes four ADCs configurable in 16-bit (1.1MSPS, differential) or 12-bit (3.5MSPS, single-ended) modes, each with dedicated S/H and hardware post-processing (offset calibration, windowed compare, DAC-referenced comparators).
Control peripherals include 24 ePWM channels (16 with high-resolution A/B edges), six eCAP modules, three eQEP interfaces, and eight SDFM input channels supporting parallel filtering for shunt-based current measurement. Communications are served by two CAN 2.0B modules, four SCIs, three SPIs, two I²Cs, one USB 2.0 MAC+PHY, and a uPP interface-all pin-bootable and multiplexed across its 100-pin HTQFP footprint.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28375SPTP | Same silicon, 176-pin HLQFP package with 97 GPIOs and EMIF support - larger footprint, higher I/O count, and external memory interface capability. | Preferred for designs requiring external SDRAM/ASRAM (e.g., HMI-enabled inverters) or more GPIOs for auxiliary sensors/actuators. | Select TMS320F28375SPTP when board layout allows larger package and external memory expansion is needed; not pin-compatible with PZP. |
| TMS320F28377SPZPS | Same 100-pin HTQFP package but with 1MB flash, 164KB RAM, and full 169 GPIO support - higher memory and I/O capacity within identical mechanical envelope. | Suitable for next-generation designs needing larger control algorithm storage or additional peripheral routing (e.g., dual CAN + USB + uPP simultaneously). | Choose TMS320F28377SPZPS if firmware complexity or future feature scalability demands >512KB flash; pinout matches but memory map differs. |
Compared with TMS320F28375SPZPS, the TMS320F28375SPTP offers expanded I/O and EMIF at the cost of board area, while TMS320F28377SPZPS delivers double flash/RAM in the same 100-pin footprint - enabling algorithm upgrades without PCB revision, though requiring memory-aware linker configuration.
