Product details
Overview
TMS320F28376DZWTT 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-precision motor control in EV traction inverters and solar power converters.
For engineers reviewing the TMS320F28376DZWTT datasheet, TMS320F28376DZWTT pinout, TMS320F28376DZWTT application, or TMS320F28376DZWTT equivalent, key selection criteria include dual-CPU deterministic latency, CLA offload capability for time-critical loops, 16-bit ADC resolution with hardware post-processing, functional safety certification up to ASIL B/SIL 2, and nFBGA-337 packaging for thermal performance in high-power density systems.
Technical Context
The TMS320F28376DZWTT 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/flux loops and system-level 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 integrated S/H and hardware-accelerated post-processing (offset calibration, windowed compare, DAC-referenced comparators). The Sigma-Delta Filter Module (SDFM) provides eight input channels with parallel filtering for isolated current sensing.

FAQ
What is the maximum operating junction temperature for the TMS320F28376DZWTT?
The TMS320F28376DZWTT is rated for a junction temperature range of –40°C to 105°C, as indicated by the 'T' temperature grade suffix in its part number. This specification is validated per TI's recommended operating conditions and thermal resistance characteristics in the official datasheet SPRS880P. The nFBGA package's thermal performance supports sustained operation under high ambient loads in motor control and power conversion applications. Always verify PCB layout and heatsinking against TI's thermal design guidelines for TMS320F28376DZWTT.
Does the TMS320F28376DZWTT support functional safety certification out of the box?
Yes, the TMS320F28376DZWTT is developed for functional safety applications and carries hardware integrity certification to ASIL B (ISO 26262) and SIL 2 (IEC 61508) by TÜV SÜD. It includes safety-related features such as ECC-protected flash and RAM, hardware BIST, windowed watchdog timers, and dual-clock domain monitoring. While the device itself meets these levels, full system-level certification (e.g., ASIL D) requires integration with TI's safety documentation, diagnostic software libraries, and proper system architecture-available through TI's Functional Safety Resource Center for TMS320F28376DZWTT.
How many ADC channels does the TMS320F28376DZWTT support in 16-bit differential mode?
The TMS320F28376DZWTT supports 12 external differential input channels across its four independent 16-bit ADCs-three channels per ADC. Each ADC operates at up to 1.1MSPS in this mode, delivering 915ns conversion time. The device provides dedicated ADCINx pins grouped by ADC instance (e.g., ADCINA0–A5, ADCINB0–B5), with full pinout details in Section 5.1 of the SPRS880P datasheet. All four ADCs are fully functional in the ZWT package variant used by TMS320F28376DZWTT.
Can the CLA coprocessors in the TMS320F28376DZWTT execute code independently of the main C28x CPUs?
Yes, the two CLA coprocessors in the TMS320F28376DZWTT run at 200MHz and execute IEEE 754 single-precision floating-point code completely independently of the main C28x CPUs. They respond to peripheral interrupts (e.g., ADC end-of-conversion, PWM timer overflow) and access shared memory via dedicated message RAMs. This allows time-critical control tasks-such as current loop regulation or SDFM data filtering-to be offloaded without CPU scheduling latency, as confirmed in the TMS320F28376DZWTT Technical Reference Manual and SPRS880P datasheet.
What package type and ball count does the TMS320F28376DZWTT use?
The TMS320F28376DZWTT uses the 337-ball New Fine Pitch Ball Grid Array (nFBGA) package, identified by the 'ZWT' suffix. Its mechanical dimensions are 16mm × 16mm with a 0.8mm ball pitch. This package is lead-free and RoHS-compliant, optimized for thermal dissipation in high-power-density applications like motor drives and inverters. Pin assignments and quadrant diagrams are provided in Figures 5-1 through 5-4 of the TMS320F28376DZWTT datasheet SPRS880P.
