Product details
Overview
TMS320F28377DZWTT from Texas Instruments is a dual-core 32-bit real-time microcontroller with two 200MHz C28x CPUs, IEEE 754 FPU, TMU, VCU-II, and two 200MHz CLAs-designed for high-precision motor control, digital power conversion, and EV charging systems requiring deterministic latency and concurrent processing.
For engineers reviewing the TMS320F28377DZWTT datasheet, TMS320F28377DZWTT pinout, TMS320F28377DZWTT application, or TMS320F28377DZWTT equivalent, key selection criteria include dual-CPU/CLA partitioning for torque+position loops, 4× 16-bit ADCs (1.1MSPS each), 24 ePWM channels with 16 HRPWM, functional safety certification up to ASIL B/SIL 2, and nFBGA-337 package thermal performance in industrial and automotive traction inverters.
Technical Context
The TMS320F28377DZWTT implements a tightly coupled dual-C28x architecture where each CPU runs at 200MHz with dedicated FPU, TMU, and VCU-II-enabling simultaneous execution of fast Fourier transforms, trigonometric torque calculations, and Viterbi decoding. Each core has independent 2K×16 local RAM, 6× 2K×16 local shared RAM, and access to 128KB global shared RAM.
Two CLA coprocessors operate at 200MHz, respond to peripheral triggers (ePWM, ADC, eCAP), and execute floating-point code independently-offloading time-critical closed-loop tasks like current regulation while freeing main CPUs for communication, diagnostics, and system management.

Applications
| Motor Drive Control | EV Charging Power Module |
|---|---|
Use Scenario: Closed-loop field-oriented control (FOC) of 3-phase PMSM/BLDC motors in HVAC compressors and traction inverters. IC Role / Device Role / Timing Role: Dual-core executes position estimation (CPU1) and current regulation (CPU2), while CLAs handle PWM update and ADC trigger synchronization within 100ns jitter. Use Value: Enables <1µs current loop execution at 20kHz switching frequency, improving torque ripple suppression and efficiency over single-core alternatives. | Use Scenario: Bidirectional AC/DC and DC/DC conversion in Level 2 and DC fast-charging stations. IC Role / Device Role / Timing Role: Manages interleaved LLC resonant converter control, grid synchronization (via eQEP/SCI), and isolation monitoring using CMPSS windowed comparators. Use Value: Integrates 4× ADCs for simultaneous AC voltage/current, DC bus, and thermal sensing-reducing BOM count versus multi-IC solutions. |
| Solar String Inverter | Industrial UPS System |
Use Scenario: MPPT tracking and grid-synchronized inversion in residential/commercial solar string inverters. IC Role / Device Role / Timing Role: CPU1 runs MPPT algorithm with TMU-accelerated arctan; CPU2 handles grid-tie PWM generation and harmonic compensation via HRPWM and SDFM-filtered current feedback. Use Value: Achieves >98.5% peak efficiency and THD <3% at full load through deterministic 150ps PWM edge placement and real-time harmonic injection. | Use Scenario: Three-phase online UPS with seamless transfer, battery management, and active harmonic filtering. IC Role / Device Role / Timing Role: Coordinates dual EMIF interfaces-one for battery-side DC-DC control, another for AC output inverter-using DMA-driven data movement between flash/RAM and peripherals. Use Value: Eliminates need for external FPGA co-processor by integrating uPP interface for high-speed status exchange with supervisory MCU or energy meter IC. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28377DPTP | Same dual-core architecture, memory, and peripherals-but in 176-pin HLQFP package (26mm × 26mm), higher thermal resistance (θJA = 32.5°C/W vs. 22.3°C/W for ZWT) | Better suited for prototyping and lower-power designs where PCB area and thermal headroom permit larger footprint | Select ZWT for space-constrained, high-power-density applications (e.g., on-board chargers); choose PTP for lab validation or cost-sensitive industrial drives. |
| TMS320F28379DZWTT | Upgraded to 1MB flash (512KW per CPU), 204KB RAM, 8 CMPSS units (vs. 4), and extended temperature range (–40°C to 125°C junction) | Required for ASIL D system-level design support, extended-life energy storage PCS, or high-ambient-temperature traction inverters | Choose F28379D when flash/RAM headroom, enhanced protection (CMPSS), or extended temp grade is mandatory-otherwise F28377DZWTT delivers optimal cost/performance for T-grade industrial use. |
Compared with TMS320F28377DPTP, the TMS320F28377DZWTT offers superior thermal performance and smaller PCB footprint; compared with TMS320F28379DZWTT, it provides identical dual-core control capability at lower cost and reduced memory-making it ideal for volume production in industrial motor drives and solar inverters where 512KB flash suffices.

The TMS320F28377DZWTT supports up to 1.1 million samples per second (MSPS) per ADC in 16-bit mode across its four independent ADCs-yielding a total system throughput of 4.4 MSPS. Each ADC features differential inputs, hardware saturation calibration, and eight windowed comparators with 12-bit DAC references for real-time overcurrent protection.
Does the TMS320F28377DZWTT include hardware functional safety features?
Yes, the TMS320F28377DZWTT includes hardware-level functional safety features certified to ISO 26262 ASIL B and IEC 61508 SIL 2 by TÜV SÜD.

How many high-resolution PWM channels does the TMS320F28377DZWTT provide?
The TMS320F28377DZWTT provides 16 high-resolution PWM (HRPWM) channels-eight modules with complementary A/B outputs, each supporting 150ps resolution. These are exclusively available on CPU1 and enable precise gate timing for wide-bandgap power devices in high-frequency resonant converters and servo amplifiers.
Can the TMS320F28377DZWTT support isolated current sensing?
Yes, the TMS320F28377DZWTT supports isolated current sensing via its Sigma-Delta Filter Module (SDFM), which accepts oversampled bitstream inputs from external ΣΔ modulators (e.g., AMC130x). The SDFM provides two parallel filters per channel, fast out-of-range detection, and decimated 16-bit results directly usable by CPU or CLA-eliminating external ADCs in shunt-based designs.
What development tools are recommended for the TMS320F28377DZWTT?
Texas Instruments recommends the LAUNCHXL-F28379D LaunchPad development kit and C2000Ware software suite for the TMS320F28377DZWTT.
