Texas Instruments TMS320F28379DZWTQR

Overview

TMS320F28379DZWTQR 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 string inverters.

For engineers reviewing the TMS320F28379DZWTQR datasheet, TMS320F28379DZWTQR pinout, TMS320F28379DZWTQR application, or TMS320F28379DZWTQR 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/power integrity for high-density power electronics layouts.

Technical Context

The TMS320F28379DZWTQR 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 position/speed observers. Its two CLAs operate independently at 200MHz, servicing time-critical PWM updates and ADC post-processing without CPU intervention.

Peripherals are partitioned across CPU1 and CPU2 domains: CPU1 controls HRPWM-A/B channels (8 modules), SDFM-1/2, and eQEP-1/2/3; CPU2 manages EMIF1/2, USB, uPP, and CAN-B. The dual-zone DCSM security module enforces code isolation between secure boot ROM, user flash, and RAM regions.

FAQ

What is the maximum operating junction temperature for the TMS320F28379DZWTQR?

The TMS320F28379DZWTQR is rated for a junction temperature range of –40°C to 105°C (T-grade). This specification is validated per JEDEC JESD22-A104 and applies to continuous operation under specified thermal design conditions using the 16mm × 16mm nFBGA package with appropriate PCB copper pour and thermal vias. Derating is required above 85°C ambient in sealed enclosures.

Does the TMS320F28379DZWTQR support hardware-based functional safety features out of the box?

Yes, the TMS320F28379DZWTQR includes hardware safety mechanisms such as ECC on flash and RAM, lockstep-capable watchdog timers, CPU self-test (HWBIST), and dual-zone DCSM security - all validated for ISO 26262 ASIL B and IEC 61508 SIL 2 by TÜV SÜD. These features are enabled in silicon and require no external components to meet base hardware integrity requirements.

How many independent ADC modules does the TMS320F28379DZWTQR integrate, and what are their key modes?

The TMS320F28379DZWTQR integrates four independent 16-/12-bit ADC modules. Each supports 16-bit mode (1.1MSPS, differential inputs, up to 12 external channels) and 12-bit mode (3.5MSPS, single-ended inputs, up to 24 external channels). All four ADCs feature hardware post-processing including offset calibration, windowed comparators with DAC references, and trigger-to-sample delay capture - enabling real-time protection and sensor fusion without CPU load.

Can the TMS320F28379DZWTQR's CLA execute code independently of the main C28x CPUs?

Yes, each of the two CLAs in the TMS320F28379DZWTQR is a fully autonomous 32-bit floating-point processor running at 200MHz. It responds to peripheral interrupts (e.g., ADC end-of-conversion, PWM timer overflow), executes its own code from dedicated CLA RAM, and communicates with its associated C28x CPU via message RAM - enabling true parallelism for time-critical tasks like PWM update or current observer calculation.

Is the TMS320F28379DZWTQR pin-compatible with other members of the F2837xD family?

Yes, the TMS320F28379DZWTQR in the ZWT (337-ball nFBGA) package is pin-compatible with TMS320F28377DZWT, TMS320F28376DZWT, and TMS320F28375DZWT. All share identical ball-out, power/ground assignments, and peripheral pin mappings - allowing hardware reuse across performance tiers while varying flash/RAM/feature sets in firmware.
