Product details
Overview
TMS320F28379DPTPS 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 TMS320F28379DPTPS datasheet, TMS320F28379DPTPS pinout, TMS320F28379DPTPS application, or TMS320F28379DPTPS equivalent, key selection criteria include dual-CPU+CLA parallel processing capability, functional safety certification up to ASIL B/SIL 2, 1MB ECC-protected flash, 204KB RAM with parity/ECC, and support for isolated current sensing via SDFM + CMPSS.
Technical Context
The TMS320F28379DPTPS 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 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.
On-chip analog subsystem includes four ADCs configurable in 16-bit (1.1MSPS, differential) or 12-bit (3.5MSPS, single-ended) mode, each with integrated S/H and hardware post-processing (offset calibration, windowed compare, DAC-referenced comparators). The eight-channel SDFM supports sigma-delta modulator inputs for isolated shunt current measurement.

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 | 512KB flash (256KB per CPU), 172KB RAM, 97 GPIOs, no CLB, reduced ADC count (2 ADCs), no SDFM | Suitable for cost-sensitive motor drives with lower channel count and no isolated current sensing | Select when system requires only single-axis control, smaller code footprint, and no functional safety certification |
| TMS320F28379DZWT | Same core/peripheral spec but in 337-ball nFBGA (16mm × 16mm), higher pin density, better thermal performance via solder ball array | Preferred for space-constrained, high-power-density designs (e.g., onboard chargers, servo drives) | Select when PCB area is constrained and thermal management via package bottom-side conduction is required |
Compared with TMS320F28377DPTP, the TMS320F28379DPTPS offers double flash/RAM, full SDFM/CMPSS/CLB support, and ASIL B certification - making it suitable for safety-critical, multi-axis, or high-fidelity sensing systems; versus TMS320F28379DZWT, it trades board area for easier routing and thermal pad accessibility in HLQFP form factor.
