Key Features
- Dual C28x cores each at 200 MHz plus 2 control law accelerator (CLA) coprocessors enabling fully parallel real-time control pipelines
- AEC-Q100 Grade 0 automotive qualification for operation up to +125°C junction temperature in motor drive and inverter systems
- 16-bit ADC with up to 24 channels and simultaneous sampling minimizing phase error in multi-phase power conversion
- SafeTI diagnostic library with BIST and hardware redundancy for ISO 26262 ASIL B functional safety requirements
Applications
The TMS320F28379SPTPQ is the preferred DSP for automotive traction inverters, on-board EV chargers, and industrial servo drives where dual-core real-time control at 200 MHz must satisfy automotive functional safety requirements. Its hardware CLA offloads control law computations from the main C28x core, reducing interrupt latency to under 1 µs for high-bandwidth current control loops. Grid-tied solar inverters and power factor correction stages also use this device for its 24-channel simultaneous-sampling ADC, which eliminates phase-current measurement errors across multi-phase topologies.

Frequently Asked Questions
How many CPU cores does TMS320F28379SPTPQ have, and at what clock frequency do they operate?
TMS320F28379SPTPQ integrates 2 independent C28x CPU cores, each running at up to 200 MHz, plus 2 control law accelerator (CLA) coprocessors. This quad-engine architecture allows one core to handle communications while the other executes real-time control loops at sub-1-µs cycle times.
Which automotive qualification grade does TMS320F28379SPTPQ meet, and what temperature range does that cover?
The device carries AEC-Q100 Grade 0 qualification, covering a junction temperature range of -40°C to +150°C. This is mandatory for under-hood automotive applications such as traction inverters and EV battery management modules where ambient temperatures can reach +125°C continuously.
For a 3-phase traction inverter, how does the 16-bit simultaneous-sampling ADC of TMS320F28379SPTPQ improve current measurement accuracy?
Simultaneous sampling of up to 24 ADC channels eliminates phase skew between current measurements on different motor phases. With 16-bit resolution providing 65536 levels across a ±3.3V input range, phase current errors drop below 0.01%, which is critical for field-oriented control algorithms requiring precise torque estimation at 200 MHz loop rates.
When is TMS320F28379SPTPQ selected over TMS320F28377S in dual-core industrial motor drive designs?
TMS320F28379SPTPQ is chosen when designs need AEC-Q100 automotive qualification or the extended -40°C to +150°C Grade 0 temperature rating unavailable on TMS320F28377S. Both share the same 176-pin LQFP footprint and software-compatible C28x ISA, so migrating requires only linker script and clock configuration changes rather than full board redesign.
