Product details
Overview
TMS320F28377SPTPT from Texas Instruments is a 32-bit floating-point real-time microcontroller featuring a 200MHz C28x CPU, IEEE 754 FPU, Trigonometric Math Unit (TMU), and Viterbi/Complex Math Unit (VCU-II); it integrates dual 16-/12-bit ADCs (1.1MSPS/3.5MSPS), 24 ePWM channels with 16 HRPWM, 2 CAN modules, USB 2.0 (MAC+PHY), and CLA coprocessor - deployed in solar inverters, EV traction inverters, and industrial motor drives.
For engineers reviewing the TMS320F28377SPTPT datasheet, TMS320F28377SPTPT pinout, TMS320F28377SPTPT application, or TMS320F28377SPTPT equivalent, key selection considerations include its -40°C to 125°C junction temperature rating, 176-pin HLQFP (PTP) package with PowerPAD™ thermal enhancement, 1MB flash/ECC, 164KB RAM/ECC, and functional safety compliance up to ASIL B/SIL 2.
Technical Context
The TMS320F28377SPTPT implements a single-core C28x CPU subsystem running at 200MHz with dedicated CLA coprocessor also at 200MHz, enabling parallel execution of time-critical control loops while the main CPU handles communications and diagnostics. Its analog subsystem includes four independent 16-/12-bit ADCs with hardware post-processing (offset calibration, windowed comparators, DAC-referenced thresholds) and eight SDFM input channels for isolated current sensing.
System-level integration is reinforced by two EMIFs (ASRAM/SDRAM), 6-channel DMA, 169 GPIOs with input filtering, dual-zone security, and configurable logic blocks (CLB) supporting position manager functions. The device supports ISO 11898-1/CAN 2.0B, USB 2.0, uPP, three SPIs, four SCIs, two I²Cs, and two McBSPs - all accessible in the PTP package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28379SPTPT | Same PTP package, dual-CPU/CLA architecture, 1MB flash, 164KB RAM - adds second C28x+CLA subsystem and extra peripherals. | Required for applications needing parallel control domains (e.g., dual-motor control or master/slave topology). | Select when computational headroom exceeds TMS320F28377SPTPT's single-CLA capacity or when dual independent control loops are architecturally mandated. |
| TMS320F28375SPTPT | Same PTP package but reduced memory: 512KB flash, 132KB RAM; fewer ADCs (2), ePWMs (15), and SDFM channels (6). | Suitable for cost-sensitive, lower-channel-count applications like single-phase inverters or smaller servo drives. | Choose for simplified BOM and lower unit cost where full TMS320F28377SPTPT peripheral count and memory are not utilized. |
Compared with TMS320F28379SPTPT, the TMS320F28377SPTPT offers identical package and thermal performance but trades dual-core capability for lower cost and power; versus TMS320F28375SPTPT, it delivers 100% more flash, 24% more RAM, and full 4-ADC/24-ePWM capability - making it optimal for mid-tier industrial inverters requiring functional safety and scalability.
