Product details
Overview
TMS320F28379SPTPS from Texas Instruments is a 32-bit floating-point real-time microcontroller with dual 200MHz C28x CPU and CLA coprocessor, IEEE 754 FPU, TMU, VCU-II, 1MB flash (ECC-protected), 164KB RAM (ECC/parity-protected), and integrated analog subsystem including four 16-/12-bit ADCs (up to 4.4MSPS total), three 12-bit DACs, and eight SDFM channels - deployed in EV traction inverters and solar string inverters.
For engineers reviewing the TMS320F28379SPTPS datasheet, TMS320F28379SPTPS pinout, TMS320F28379SPTPS application, or TMS320F28379SPTPS equivalent, key selection considerations include its –40°C to 125°C junction temperature rating, 176-pin HLQFP (PTP) package with PowerPAD™ thermal enhancement, functional safety compliance up to ASIL B/SIL 2, and support for high-resolution PWM (16 HRPWM channels) and dual CAN interfaces.
Technical Context
The TMS320F28379SPTPS implements a single-CPU, single-CLA subsystem architecture (vs. dual-CPU F2837xD), enabling deterministic real-time control with parallel execution of time-critical algorithms on the CLA while the main C28x CPU handles communications and diagnostics. Its analog subsystem integrates hardware-accelerated post-processing including windowed comparators with 12-bit DAC references and saturating offset calibration per ADC channel.
System-level timing is managed via two internal zero-pin 10MHz oscillators, on-chip crystal oscillator, and missing-clock detection circuitry. The device supports multiple low-power modes with external wakeup and features dual-zone security with unique identification number and OTP memory for third-party code protection.

FAQ
What is the maximum operating junction temperature for the TMS320F28379SPTPS?
The TMS320F28379SPTPS is rated for a maximum junction temperature of 125°C, confirmed by TI's official datasheet revision February 2024 (SPRS881K). This S-grade temperature specification enables deployment in under-hood automotive power modules and high-ambient industrial environments without derating. The device incorporates thermal shutdown circuitry and supports junction temperature monitoring via its integrated analog temperature sensor.
Does the TMS320F28379SPTPS support pin-compatible migration from other F2837xS devices?
Yes, the TMS320F28379SPTPS is pin-compatible with other 176-pin PTP-package F2837xS variants including TMS320F28377SPTPS and TMS320F28378SPTPS. All share identical mechanical footprint, power/ground ball map, and peripheral pin assignments per TI's device comparison table. Migration requires only firmware and configuration updates - no PCB redesign is necessary when moving between these PTP variants.
How many high-resolution PWM channels does the TMS320F28379SPTPS provide?
The TMS320F28379SPTPS provides 16 high-resolution PWM (HRPWM) channels, implemented across eight ePWM modules where both A and B outputs support high-resolution edge placement. Each HRPWM channel achieves ≤150ps resolution and supports independent dead-band insertion, trip-zone protection, and event synchronization - critical for minimizing switching losses in SiC/GaN-based inverters.
Is the TMS320F28379SPTPS qualified for automotive applications?
No, the TMS320F28379SPTPS is not AEC-Q100 qualified. It carries an 'S' temperature grade (–40°C to 125°C junction) but lacks the automotive-specific qualification testing and documentation of Q1-rated variants such as TMS320F28377S-Q1. For automotive use cases requiring AEC-Q100 compliance, TI recommends selecting the Q1-suffixed part numbers instead.
What analog-to-digital conversion performance does the TMS320F28379SPTPS deliver in 16-bit mode?
In 16-bit mode, each of the four ADCs in the TMS320F28379SPTPS achieves 1.1MSPS sampling rate with differential input support and 12-channel capacity per ADC. System-level throughput reaches 4.4MSPS with hardware-synchronized conversions. Conversion time is 915ns, and built-in post-processing includes saturating offset calibration and error-from-setpoint calculation - enabling direct integration into precision current/voltage feedback loops.
