Product details
Overview
TMS320F28377DZWTQ 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 independent 200MHz CLA coprocessors. It integrates four 16-/12-bit ADCs (up to 4.4MSPS system throughput), 24 ePWM channels (16 HRPWM), dual CAN, USB 2.0, and 169 GPIOs. It targets high-performance motor control in EV traction inverters and solar power converters.
For engineers reviewing the TMS320F28377DZWTQ datasheet, TMS320F28377DZWTQ pinout, TMS320F28377DZWTQ application, or TMS320F28377DZWTQ equivalent, key selection criteria include dual-CPU real-time partitioning, ASIL B/SIL 2 functional safety certification, nFBGA-337 thermal performance, 169-pin I/O scalability, and integrated analog control peripherals for closed-loop timing-critical systems.
Technical Context
The TMS320F28377DZWTQ implements a tightly coupled dual-C28x architecture where each CPU runs at 200MHz with dedicated FPU, TMU, and VCU-II-enabling simultaneous torque/position loop execution and fast trigonometric/complex math. Each core pairs with a 200MHz CLA that responds to peripheral triggers and executes time-critical control law code independently.
Its analog subsystem includes four independent ADCs supporting both 16-bit (1.1MSPS, differential) and 12-bit (3.5MSPS, single-ended) modes, plus eight SDFM input channels with configurable sigma-delta filtering and three 12-bit buffered DACs-all synchronized to PWM timers for deterministic sampling and actuation.

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 |
|---|---|---|---|
| TMS320F28377D-Q1 | Identical silicon; automotive-qualified with AEC Q100 Grade 1 (–40°C to 125°C free-air) and extended reliability testing | Required for automotive OEM designs needing full PPAP documentation and automotive qualification traceability | Select TMS320F28377D-Q1 when automotive qualification, failure-in-time (FIT) data, or automotive change notification is mandatory |
| TMS320F28379D | Higher memory: 1MB flash (vs. 512KB) and 204KB RAM (vs. 172KB); adds CLB tile count from 4 to 4 (same), but enables larger control algorithms and data buffers | Better suited for complex multi-axis motion control or systems requiring extensive firmware-over-the-air (FOTA) storage | Select TMS320F28379D when application requires >512KB flash for dual-bank updates or >172KB RAM for real-time FFTs and waveform buffering |
Compared with TMS320F28377D-Q1, the TMS320F28377DZWTQ offers identical real-time control capability and pinout but lacks automotive qualification documentation; compared with TMS320F28379D, it trades memory headroom for cost-sensitive industrial deployments where 512KB flash and 172KB RAM suffice.

FAQ
What is the maximum operating junction temperature for the TMS320F28377DZWTQ?
The TMS320F28377DZWTQ is rated for a maximum junction temperature of 125°C. Its Q-grade qualification specifies operation from –40°C to 125°C free-air temperature, and thermal design must ensure junction temperature remains within this limit under worst-case power dissipation and ambient conditions. The nFBGA package's exposed thermal pad enables efficient heat transfer to the PCB for sustained high-frequency operation.
Does the TMS320F28377DZWTQ support functional safety certification out of the box?
Yes, the TMS320F28377DZWTQ is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD. It includes hardware safety mechanisms such as ECC on flash/RAM, windowed watchdog timers, missing-clock detection, and hardware BIST. Safety documentation-including FMEDA reports, safety manuals, and diagnostic coverage analysis-is provided by Texas Instruments to support system-level certification.
How many ADC channels does the TMS320F28377DZWTQ support in 16-bit differential mode?
The TMS320F28377DZWTQ supports up to 12 external channels in 16-bit differential mode across its four independent ADC modules. Each ADC provides differential input capability, and the device's analog mux and GPIO mapping allow flexible assignment of ADCINDx, ADCINAx, ADCINBx, and ADCINCx pins to physical signals-enabling simultaneous sampling of motor phase currents and DC-link voltage.
Can the CLA coprocessors in the TMS320F28377DZWTQ execute code independently of the main C28x CPUs?
Yes, each CLA in the TMS320F28377DZWTQ is a fully autonomous 32-bit floating-point processor running at 200MHz. It responds to peripheral interrupts (e.g., ePWM timer events, ADC EOC), executes user-defined control law code from CLA RAM or flash, and communicates with its host CPU via shared message RAM-without stalling or requiring CPU intervention. This enables true parallelism for protection, sampling, or modulation tasks.
What package type and ball count does the TMS320F28377DZWTQ use?
The TMS320F28377DZWTQ uses the ZWT package: a 337-ball New Fine Pitch Ball Grid Array (nFBGA) with 16mm × 16mm body size, lead-free/green finish, and an exposed thermal pad. This package supports high I/O density (169 GPIOs), thermal performance for 200MHz dual-core operation, and compatibility with standard PCB assembly processes.
