Product details
Overview
TMS320F28377SPZPT 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); includes 1MB flash, 164KB RAM, four 16-/12-bit ADCs (up to 4.4MSPS), 24 ePWM channels with 16 HRPWM, dual CAN, USB 2.0, and CLA coprocessor - deployed in solar inverters, EV traction inverters, and industrial motor drives.
For engineers reviewing the TMS320F28377SPZPT datasheet, TMS320F28377SPZPT pinout, TMS320F28377SPZPT application, or TMS320F28377SPZPT equivalent, key selection considerations include its 176-pin HLQFP package, –40°C to 125°C junction temperature rating, single-CPU/CLA subsystem architecture, functional safety compliance (ISO 26262 ASIL B, IEC 61508 SIL 2), and integrated analog control peripherals for closed-loop power conversion systems.
Technical Context
The TMS320F28377SPZPT implements a single-core C28x CPU at 200MHz with dedicated hardware accelerators (FPU, TMU, VCU-II) and an independent 200MHz CLA coprocessor for parallel real-time control execution. Its memory subsystem includes 1MB ECC-protected flash and 164KB RAM (ECC/parity-protected), organized into secure zones with unique ID and dual-code security.
Analog integration comprises four independent 16-/12-bit ADCs supporting differential (12-channel) or single-ended (24-channel) inputs, hardware post-processing (offset calibration, windowed comparators, DAC-referenced thresholds), three 12-bit buffered DACs, eight SDFM input channels, and CMPSS with comparator-based protection logic - all synchronized to high-resolution PWM timing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28379S | Same package (PTP), dual-CPU/CLA subsystem, 1MB flash, 164KB RAM - higher compute capacity with second C28x+CLA pair. | Required for applications needing >200MHz equivalent control bandwidth or dual independent control loops (e.g., dual-motor drives). | Select TMS320F28379S when parallel CPU+CLA execution across two domains is needed; TMS320F28377SPZPT suffices for single-loop high-performance control. |

These are implemented within the 24 total ePWM channels and are essential for precise timing in SiC and GaN-based inverter designs.
What analog-to-digital converter (ADC) configurations are supported by the TMS320F28377SPZPT?
The TMS320F28377SPZPT integrates four independent ADCs configurable in 16-bit mode (1.1MSPS, differential inputs, up to 12 channels) or 12-bit mode (3.5MSPS, single-ended inputs, up to 24 channels). Each ADC includes a dedicated sample-and-hold, hardware post-processing (offset calibration, windowed compare), and trigger-to-sample delay capture for synchronized multi-channel acquisition.
