Product details
Overview
TMS320F28377SZWTT from Texas Instruments is a 32-bit floating-point real-time microcontroller with a 200MHz C28x CPU, IEEE 754 FPU, Trigonometric Math Unit (TMU), and Viterbi/Complex Math Unit (VCU-II), designed for high-precision closed-loop motor control in industrial inverters and EV power modules. It integrates dual-zone security, 1MB ECC-protected flash, 164KB ECC/parity-protected RAM, four 16-bit ADCs (1.1MSPS each), 24 ePWM channels including 16 HRPWM, and two CAN 2.0B modules.
For engineers reviewing the TMS320F28377SZWTT datasheet, TMS320F28377SZWTT pinout, TMS320F28377SZWTT application, or TMS320F28377SZWTT equivalent, key selection criteria include its nFBGA-337 package, –40°C to 125°C junction temperature rating (S-grade), CLA coprocessor independence, SDFM support for isolated shunt sensing, and functional safety compliance up to ASIL B/SIL 2.
Technical Context
The TMS320F28377SZWTT implements a single-CPU subsystem (C28x + CLA) architecture derived from the F2837xD family but with one CPU/CLA pair enabled-enabling cost-optimized deployment while retaining full peripheral complement. Its analog subsystem includes four independent 16-/12-bit ADCs with hardware post-processing (windowed comparators, DAC-referenced thresholds, error-from-setpoint calculation), and eight SDFM input channels supporting sigma-delta current sensing.
Control execution is distributed across the main C28x CPU (200MHz, FPU/TMU/VCU-II) and the CLA (200MHz, IEEE 754 floating-point), which responds to peripheral triggers and executes time-critical tasks-such as PWM update or protection logic-concurrently with CPU firmware. The device supports ISO 11898-1 CAN 2.0B, USB 2.0 (MAC+PHY), uPP, and dual EMIFs for external memory expansion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.

| TMS320F28379S | Same package and pinout; dual-CPU/CLA subsystem (2× C28x + 2× CLA), 1MB flash, 164KB RAM | Higher computational throughput for multi-axis servo drives or radar beamforming where parallel processing is critical | Select when dual-core deterministic scheduling or >200MHz aggregate compute is required; otherwise TMS320F28377SZWTT offers optimal cost/performance balance |
| TMS320F28377S-Q1 | Identical core/peripheral spec; AEC Q100 qualified for automotive use, rated –40°C to 125°C free-air | Automotive traction inverter, battery management, or ADAS power supplies requiring automotive qualification and traceability | Select only if AEC Q100 qualification and automotive PPAP documentation are mandatory; TMS320F28377SZWTT is industrial-grade with junction-rated S-temp |
Compared with TMS320F28379S and TMS320F28377S-Q1, the TMS320F28377SZWTT delivers identical peripheral integration and S-grade thermal performance in the ZWT package but targets cost-sensitive industrial systems where dual-core compute or automotive certification are unnecessary-reducing BOM cost while preserving full feature set for single-axis motor control and power conversion.

FAQ
What is the maximum operating junction temperature for the TMS320F28377SZWTT?
The TMS320F28377SZWTT is rated for a maximum junction temperature of 125°C, consistent with its "S" temperature grade designation. This allows reliable operation in demanding industrial environments such as enclosed motor drives or high-power-density power converters without forced cooling. Thermal design must ensure that PCB layout, heatsinking, and ambient conditions keep actual junction temperature within this limit during continuous full-load operation. The device includes internal temperature sensor monitoring accessible via ADCIN15.
Does the TMS320F28377SZWTT support CAN FD or only classical CAN 2.0B?
The TMS320F28377SZWTT supports only classical CAN 2.0B (ISO 11898-1), not CAN FD. Its two D_CAN modules provide 32-message object buffers, bit rates up to 1 Mbps, and pin-bootable configuration-but lack CAN FD frame format, higher data rates, or extended payload support. For CAN FD applications, engineers should evaluate TI's TCAN4550 or newer C2000 devices like TMS320F28P65x. The TMS320F28377SZWTT remains optimal for legacy industrial automation and automotive body-control networks requiring proven CAN 2.0B interoperability.
How many independent ADC modules does the TMS320F28377SZWTT integrate, and what are their key modes?
The TMS320F28377SZWTT integrates four independent 16-/12-bit ADC modules. Each operates in 16-bit mode (1.1MSPS, differential inputs, up to 12 external channels) or 12-bit mode (3.5MSPS, single-ended inputs, up to 24 external channels). All ADCs feature dedicated Sample-and-Hold circuits, hardware post-processing (offset calibration, error-from-setpoint, windowed compare), and trigger-to-sample delay capture-enabling synchronized, low-latency current/voltage acquisition for multi-phase motor control without CPU intervention.
Is the TMS320F28377SZWTT pin-compatible with other members of the F2837xS family?
Yes, the TMS320F28377SZWTT is fully pin-compatible with other F2837xS devices in the same ZWT (337-ball nFBGA) package, including TMS320F28379S, TMS320F28376S, and TMS320F28375S. Pin assignments, power domains, and peripheral mappings match exactly across these variants. This enables hardware reuse across performance tiers-e.g., prototyping with TMS320F28379S and cost-optimizing to TMS320F28377SZWTT-without PCB redesign or layout changes.
What development tools are officially supported for the TMS320F28377SZWTT?
Texas Instruments officially supports the LAUNCHXL-F28379D LaunchPad development kit and the TMDSCNCD28379D controlCARD for the TMS320F28377SZWTT. These platforms provide JTAG debugging, on-board emulation, and access to all peripherals-including CAN, USB, and ADC-via standardized headers. TI's C2000Ware software framework, MotorControl SDK, and DigitalPower SDK deliver production-ready drivers, FOC libraries, and example projects validated for the TMS320F28377SZWTT's specific memory map and peripheral configuration.
