Product details
Overview
TMS320F28377DZWTT from Texas Instruments is a dual-core 32-bit real-time microcontroller featuring two 200MHz C28x CPUs, IEEE 754 single-precision FPU, TMU, VCU-II, and two independent 200MHz CLA coprocessors. It integrates four 16-/12-bit ADCs (up to 4.4MSPS system throughput), 24 ePWM channels with 16 HRPWM, dual CAN, USB 2.0, and 169 GPIOs - deployed in traction inverter motor control, solar string inverters, and EV charging station power modules.
For engineers reviewing the TMS320F28377DZWTT datasheet, TMS320F28377DZWTT pinout, TMS320F28377DZWTT application, or TMS320F28377DZWTT equivalent, key selection criteria include dual-CPU+CLA parallel processing capability, 169-pin nFBGA package compatibility, functional safety certification up to ASIL B/SIL 2, and support for high-resolution current sensing via SDFM + CMPSS.
Technical Context
The TMS320F28377DZWTT implements a tightly coupled dual-C28x architecture with interprocessor communication (IPC) and shared memory, enabling deterministic task partitioning - e.g., one core handling torque/current loops while the other manages communications and diagnostics. Each CPU includes dedicated FPU, TMU, and VCU-II for real-time trigonometric and complex math acceleration.
Its analog subsystem features four independent ADCs with differential 16-bit mode (1.1MSPS each), hardware post-processing (offset calibration, windowed compare, DAC-referenced comparators), and eight SDFM input channels supporting isolated shunt-based current measurement - critical for high-fidelity motor phase current feedback in closed-loop drives.

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); fewer GPIOs (97 vs. 169) and no EMIF2 | Preferred for space-constrained designs where thermal performance is managed via PowerPAD; unsuitable for SDRAM expansion or high-channel-count analog acquisition | Select when PCB layout favors QFP, thermal mass is sufficient, and external memory or full GPIO count is not required. |
| TMS320F28379DZWTT | Higher memory: 1MB flash (vs. 512KB) and 204KB RAM (vs. 172KB); adds EMIF2 and full 169 GPIO availability in same ZWT package | Required for applications needing larger firmware (e.g., multi-protocol stacks), extended data logging, or full peripheral access without pin multiplexing trade-offs | Choose when future-proofing firmware size, adding SDRAM-based buffers, or maximizing analog/digital I/O concurrency is essential. |
Compared with TMS320F28377DPTP, the TMS320F28377DZWTT offers higher I/O density and full peripheral access in compact nFBGA; versus TMS320F28379DZWTT, it trades flash/RAM capacity for cost-sensitive deployments where 512KB flash suffices for motor control firmware and safety-certified libraries.
