Product details
Overview
TMS320F28377SZWTT 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 parallel 200MHz Control Law Accelerator (CLA). It integrates four 16-bit/12-bit ADCs (up to 4.4MSPS system throughput), 24 ePWM channels with 16 HRPWM outputs, dual CAN 2.0B modules, USB 2.0 MAC+PHY, and 1MB flash with ECC-designed for high-precision motor control in EV traction inverters.
For engineers reviewing the TMS320F28377SZWTT datasheet, TMS320F28377SZWTT pinout, TMS320F28377SZWTT application, or TMS320F28377SZWTT equivalent, key selection criteria include CLA coprocessor independence, 169 GPIO count, nFBGA-337 package thermal performance, functional safety certification up to ASIL B/SIL 2, and support for isolated current sensing via SDFM + sigma-delta modulators.
Technical Context
The TMS320F28377SZWTT implements a single-CPU subsystem architecture (vs. dual-CPU F2837xD), with one C28x core and one CLA executing concurrently at 200MHz. Its analog subsystem includes four independent ADCs with differential/single-ended modes, hardware post-processing (offset calibration, windowed compare, DAC-referenced comparators), and eight SDFM input channels supporting shunt-based isolated current measurement.
Control peripherals feature 24 ePWM channels with dead-band generation on both standard and high-resolution outputs, six eCAP modules for precise timing capture, three eQEP interfaces for position feedback, and Configurable Logic Block (CLB) tiles enabling custom logic for position manager functions-critical for servo drive and inverter gate timing integrity.

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 nFBGA-337 package, 1MB flash, 164KB RAM, but adds second CLA and dual-CPU subsystem. | Required for applications needing parallel control law execution across two independent domains (e.g., dual-motor control). | Select when dual-CLA concurrency is mandatory; otherwise TMS320F28377SZWTT offers cost-optimized single-subsystem performance. |
| TMS320F28377S-Q1 | Identical core/peripheral spec, but AEC Q100 qualified for automotive use and rated for −40°C to 125°C free-air temperature. | Mandatory for under-hood automotive applications requiring automotive-grade qualification and extended temperature range. | Choose TMS320F28377S-Q1 only if AEC Q100 compliance and 125°C free-air rating are required; TMS320F28377SZWTT is commercial-grade (−40°C to 105°C junction). |
Compared with TMS320F28379S, the TMS320F28377SZWTT provides identical peripheral count and analog performance at lower cost by omitting the second CLA subsystem; versus TMS320F28377S-Q1, it trades automotive qualification for optimized pricing in industrial temperature-grade applications.

FAQ
What is the maximum operating junction temperature for the TMS320F28377SZWTT?
The TMS320F28377SZWTT is rated for a junction temperature range of −40°C to 105°C. This commercial-grade specification aligns with industrial motor drive and solar inverter ambient conditions. Thermal design must ensure junction temperature remains within this limit under full-load operation using the nFBGA-337 package's specified thermal resistance characteristics.
Does the TMS320F28377SZWTT support hardware-based functional safety features?
Yes, the TMS320F28377SZWTT includes hardware integrity features certified to ISO 26262 ASIL B and IEC 61508 SIL 2 by TÜV SÜD. These include ECC-protected memory, windowed watchdog timers, missing clock detection, and hardware built-in self-test (HWBIST)-enabling systematic safety mechanisms in certified power conversion systems.
How many independent ADC modules does the TMS320F28377SZWTT integrate?
The TMS320F28377SZWTT integrates four independent 16-bit/12-bit Analog-to-Digital Converters (ADCs), each with dedicated sample-and-hold circuitry and hardware post-processing. This allows simultaneous sampling of up to 24 single-ended or 12 differential analog signals-essential for multi-phase current and voltage monitoring in inverters.
Can the TMS320F28377SZWTT execute control algorithms independently on the CLA and main CPU?
Yes, the TMS320F28377SZWTT features a fully autonomous Control Law Accelerator (CLA) that executes IEEE 754 floating-point code concurrently with the main C28x CPU at 200MHz. The CLA responds to peripheral triggers (e.g., ADC end-of-conversion) and uses dedicated message RAM-enabling deterministic, low-latency execution of time-critical control loops without CPU intervention.
What communication interfaces are available on the TMS320F28377SZWTT for industrial networking?
The TMS320F28377SZWTT provides two ISO 11898-1/CAN 2.0B-compliant modules, four SCI/UART interfaces, two I²C ports, three SPI ports, two McBSPs, and a USB 2.0 MAC+PHY.
