Product details
Overview
TMS320F28377DZWTQR 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 high-resolution outputs, 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 TMS320F28377DZWTQR datasheet, TMS320F28377DZWTQR pinout, TMS320F28377DZWTQR application, or TMS320F28377DZWTQR equivalent, key selection criteria include dual-CPU deterministic latency, CLA offload capability for time-critical loops, 169-pin nFBGA package thermal performance, and functional safety documentation up to ASIL B/SIL 2.
Technical Context
The TMS320F28377DZWTQR implements a tightly coupled dual-C28x architecture where each CPU runs at 200MHz with dedicated FPU, TMU, and VCU-II - enabling simultaneous execution of torque/position control and diagnostics. Its two CLAs operate independently at 200MHz, respond to peripheral triggers, and execute floating-point code without CPU intervention.
On-chip analog subsystem includes four ADCs supporting both 16-bit (1.1MSPS, differential) and 12-bit (3.5MSPS, single-ended) modes, each with S/H, hardware post-processing (offset calibration, windowed compare), and integrated 12-bit DAC references. The 337-ball nFBGA (ZWT) package supports full peripheral access including dual EMIF, uPP, and 8 SDFM channels.

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 |
|---|---|---|---|
| TMS320F28379DZWT | 1MB flash (vs. 512KB), 204KB RAM (vs. 172KB), same dual-core/CLA/ADC/peripheral set - no pinout or timing change. | Required for larger firmware images (e.g., dual OTA partitions) or extended data logging buffers in energy storage PCS. | Select when >512KB flash is needed; identical ZWT package and footprint allow drop-in replacement if board layout reserves space for full memory mapping. |
| TMS320F28377DPTP | 176-pin HLQFP package (vs. 337-ball nFBGA); reduced GPIO count (97 vs. 169); same core/peripheral functionality but fewer ADC/ePWM channels accessible. | Suitable for cost-sensitive, lower-I/O industrial drives where thermal constraints favor QFP over BGA. | Choose for simplified assembly and thermal management in non-dense layouts; verify peripheral pin availability per TI's 176-pin signal mapping table before migration. |

The TMS320F28377DZWTQR supports up to 3.5MSPS per ADC in 12-bit mode, delivering a total system throughput of 14MSPS across its four independent ADCs. This enables simultaneous sampling of multiple motor phase currents and DC-link voltage with sub-285ns conversion time, critical for high-frequency current control in SiC-based inverters.
Does the TMS320F28377DZWTQR support functional safety certification for automotive use?
Yes, the TMS320F28377DZWTQR is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD. Its hardware integrity meets ASIL B requirements, and TI provides safety documentation (FMEDA, safety manual, diagnostic libraries) to support system-level ASIL D development in automotive traction inverters and charging systems.
How many high-resolution PWM channels does the TMS320F28377DZWTQR provide, and what is their timing resolution?
The TMS320F28377DZWTQR provides 16 high-resolution ePWM channels (8 modules × A/B outputs) with <150ps resolution. This precision enables accurate dead-time insertion and gate drive timing for wide-bandgap devices like SiC MOSFETs and GaN HEMTs in high-efficiency power converters.
Can the TMS320F28377DZWTQR execute code independently on both CPUs and CLAs simultaneously?
Yes - the TMS320F28377DZWTQR features two independent C28x CPUs and two CLAs, all running at 200MHz. Each CLA responds to peripheral interrupts (e.g., ADC end-of-conversion) and executes floating-point code concurrently with its associated CPU, enabling true parallel task partitioning without shared resource contention.
What package type and thermal characteristics define the TMS320F28377DZWTQR?
The TMS320F28377DZWTQR uses a 337-ball nFBGA (ZWT) package, 16mm × 16mm body size, with exposed thermal pad. Its θJA is 21.5°C/W (JEDEC High-K board), enabling operation up to 105°C junction temperature - ideal for convection-cooled motor drive control boards with high power density.
