Product details

Overview

TMS320F28377DZWTS 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 - deployed in traction inverter motor control and solar power optimizers.

For engineers reviewing the TMS320F28377DZWTS datasheet, TMS320F28377DZWTS pinout, TMS320F28377DZWTS application, or TMS320F28377DZWTS equivalent, key selection criteria include dual-CPU real-time determinism, on-chip analog subsystem precision (16-bit ADC with hardware post-processing), functional safety certification (ISO 26262 ASIL B, IEC 61508 SIL 2), and nFBGA-337 thermal performance for high-power industrial inverters.

Technical Context

The TMS320F28377DZWTS implements a tightly coupled dual-C28x architecture where each CPU runs at 200MHz with dedicated FPU, TMU, and VCU-II - enabling concurrent execution of torque/flux loops and system-level diagnostics. Its two CLAs operate independently at 200MHz, servicing peripheral-triggered tasks like PWM update or ADC post-processing without CPU intervention.

Hardware-accelerated analog control includes four ADCs supporting simultaneous 16-bit (1.1MSPS each) or 12-bit (3.5MSPS each) sampling, integrated SDFM for isolated shunt current sensing, eight windowed comparators with 12-bit DAC references, and three buffered 12-bit DAC outputs - all synchronized to ePWM timebases for deterministic closed-loop timing.

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 (PTP) package - larger footprint, lower I/O density, reduced thermal performance vs. nFBGA.	Better suited for prototyping or low-volume industrial controls where manual soldering or socketing is preferred over BGA reflow.	Select TMS320F28377DPTP when board assembly constraints prohibit BGA or when thermal margin is less critical than layout simplicity.
TMS320F28379DZWTS	Higher memory: 1MB flash (vs. 512KB), 204KB RAM (vs. 172KB), full 169 GPIOs enabled, and enhanced analog features including 24 ADC input pins (vs. 20) and 8 CMPSS units (vs. 8 - same count).	Targeted at next-generation systems requiring larger firmware images, more sensor inputs, or higher channel-count motor control (e.g., dual-axis servo drives).	Select TMS320F28379DZWTS when firmware complexity exceeds 512KB or when full ADC/CMPSS channel utilization is required across all four converters.

Compared with TMS320F28377DZWTS, the TMS320F28377DPTP offers identical functionality in a through-hole–friendly package but trades thermal efficiency and I/O density for manufacturability; the TMS320F28379DZWTS extends memory and analog channel capacity for scalable designs without changing core architecture or safety certification.

FAQ

What is the maximum ADC sampling rate supported by the TMS320F28377DZWTS in 16-bit mode?

The TMS320F28377DZWTS supports up to 1.1MSPS per ADC in 16-bit mode, with four independent ADCs delivering a total system throughput of 4.4MSPS. Each ADC includes a dedicated sample-and-hold circuit and hardware post-processing - enabling synchronized, high-precision acquisition across multiple motor phases or power stages without CPU overhead. This rate is confirmed in the device's Electrical Characteristics table (Section 6.10) and validated in application reports for FOC implementations.

Does the TMS320F28377DZWTS support functional safety certification for automotive use?

Yes, the TMS320F28377DZWTS is qualified to AEC-Q100 Grade 1 (–40°C to 125°C junction) and carries ISO 26262 ASIL B and IEC 61508 SIL 2 certification issued by TÜV SÜD. Its hardware integrity meets ASIL B requirements, and safety documentation - including FMEDA, safety manuals, and diagnostic coverage analysis - is available to support system-level ASIL D development. The "S" suffix explicitly denotes the automotive-qualified temperature grade.

How many high-resolution PWM (HRPWM) channels does the TMS320F28377DZWTS provide, and what is their timing resolution?

The TMS320F28377DZWTS provides 16 HRPWM channels - eight modules, each with high-resolution A and B outputs. Resolution is programmable down to 150ps, achieved via digital fractional delay logic synchronized to the 200MHz system clock. This enables precise dead-time control and gate driver timing for wide-bandgap power devices in high-frequency inverters, as specified in Section 6.11 of the datasheet.

What package type and ball count does the TMS320F28377DZWTS use, and is it RoHS compliant?

The TMS320F28377DZWTS uses the ZWT package: a 337-ball New Fine Pitch Ball Grid Array (nFBGA) with 0.5mm pitch and 16mm × 16mm body size. It is lead-free and RoHS-compliant, meeting JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) requirements. Pin diagrams and mechanical drawings are provided in Section 11.1 of the official datasheet (SPRS880P).

Can the TMS320F28377DZWTS execute code independently on both C28x CPUs and CLAs simultaneously?

Yes, the TMS320F28377DZWTS supports fully independent concurrent execution: both C28x CPUs run separate firmware images at 200MHz, and each has an associated CLA coprocessor that executes floating-point code triggered by peripheral events (e.g., ADC EOC, PWM timer match). Communication occurs via shared message RAM and IPC hardware - verified in TI's C2000Ware examples and documented in Section 7.9 of SPRS880P.
