TMS320F28379D-Q1 概要
A real-time microcontroller (MCU) is a single-chip processor that executes deterministic control loops for power conversion, motor drive, and vehicle systems. Within the semiconductor hierarchy it sits in the 32-bit MCU / DSP family, and TI's C2000 Delfino platform targets high-performance digital control where cycle-accurate timing matters more than general-purpose throughput.
Key features include dual C28x cores with 200 MHz operation, 1024 KB flash, 16-bit ADCs, the Configurable Logic Block (CLB) for custom digital logic, the External Memory Interface (EMIF) for parallel memory expansion, and AEC-Q100 automotive qualification. The dual-core architecture allows one core to run control loops while the other handles communication and diagnostics, and the Functional Safety (FuSa) package supports safety-relevant designs.
Architecturally, the device pairs each C28x with a CLA floating-point coprocessor, so trigonometric (TMU) and filter computations run in parallel with the main control code. Twelve 16-bit ADC channels groups and high-resolution PWM peripherals make it a natural fit for field-oriented motor control.
Typical applications include automotive traction inverters, onboard chargers, servo drives, solar inverters, and industrial power supplies.
Design-wise, the 337-ball NFBGA requires careful BGA layout, power-plane segmentation, and consideration of the dual-rail power-up sequencing.

主な用途
TMS320F28379D-Q1 の用途: 6 件s: Automotive Traction Inverter, Onboard Charger and DC-DC Converter, Industrial Servo Drives, Solar Inverters and Energy Storage, Automotive Domain and Body Controllers, Test and Measurement Equipment.
Automotive Traction Inverter
The TMS320F28379D-Q1's dual C28x cores at 200 MHz (800 MIPS) execute field-oriented control at 10-20 kHz PWM frequencies while the second core runs functional-safety monitoring, and its AEC-Q100 qualification is mandatory for powertrain deployment. The TMU accelerates Park/Clarke transformations and the 16-bit ADCs capture phase currents with the resolution needed for low-torque-ripple control. The CLB implements resolver or encoder interfaces in hardware, offloading the CPU. Placed at the center of the inverter control board with gate-driver ICs such as the UCC21750, it delivers deterministic single-cycle control latency that switching converters require.
おすすめ
Onboard Charger and DC-DC Converter
For 3.3-22 kW onboard chargers, the TMS320F28379D-Q1 combines 1024 KB flash for full power-factor-correction, LLC, and communication stacks with the 16-bit ADCs needed for precise current sharing and voltage regulation. Dual cores allow PFC and DC/DC stages to be controlled independently while a CLA handles protection math, and the CLB can implement fast hardware-level fault trip logic within nanoseconds, faster than any software interrupt path. Its AEC-Q1 qualification covers the harsh under-hood thermal environment. DesignDRIVE and DigitalPower SDK reference designs shorten development cycles for bidirectional (V2G) charger topologies.
おすすめ
Industrial Servo Drives
Industrial servo drives demand cycle-accurate current loops, high-resolution position feedback, and multi-axis coordination - all strengths of the TMS320F28379D-Q1. The 800 MIPS dual-core architecture runs field-oriented control plus EtherCAT or industrial Ethernet stacks concurrently, while DesignDRIVE Position Manager interfaces directly with analog (sin/cos) and digital (EnDat, BiSS) position sensors. The 16-bit ADCs and on-chip comparators create sub-microsecond overcurrent protection paths. Although this automotive-graded device exceeds industrial requirements, using one BOM across automotive and industrial drive platforms simplifies qualification and spares management for mixed-market OEMs.
おすすめ
Solar Inverters and Energy Storage
Grid-tied solar string inverters and battery energy storage converters use the TMS320F28379D-Q1's dual cores to split MPPT/boost control from grid-side inverter control and grid-code compliance monitoring. Its 1024 KB flash holds MPPT algorithms, PLL grid synchronization, and communication protocols without external memory, while EMIF supports expansion if needed. The 16-bit ADCs achieve the measurement accuracy required for sub-1% power metering accuracy classes, and the CLB provides hardware-based anti-islanding trip logic. High PSRR-sensitive analog references are onboard, and the deterministic C28x interrupt latency keeps harmonic distortion low across the switching operating envelope.
おすすめ
Automotive Domain and Body Controllers
Beyond traction, the TMS320F28379D-Q1 serves zonal control units that aggregate motor, solenoid, and sensor loads. Its 800 MIPS dual-core performance with lockstep-capable safety architecture supports ASIL-rated monitoring, the CLB replaces small CPLDs for custom PWM and diagnostic logic, and the EMIF interfaces legacy parallel peripherals during platform transitions. Multiple 16-bit ADC channels consolidate current, voltage, and temperature sensing from distributed loads. The 337-ball NFBGA offers the I/O density zonal controllers need within a compact 16 x 16 mm footprint. Choosing the -Q1 grade from the start avoids requalification when a platform later migrates into vehicle applications.
おすすめ
Test and Measurement Equipment
Programmable power supplies, electronic loads, and power analyzers exploit the TMS320F28379D-Q1's combination of 16-bit ADCs, fast control bandwidth, and 1024 KB flash for protocol and UI stacks. The dual-core architecture isolates real-time regulation loops (core 1) from USB/Ethernet communication and display management (core 2), preventing control jitter from communication load - a common pitfall in single-core designs. The TMU accelerates RMS, THD, and FFT-based measurement computations in firmware. Although the commercial TMS320F28379D is sufficient for bench instruments, OEMs standardizing on the -Q1 across product families benefit from a single qualified component database entry.

設計ノート
The 337-ball NFBGA (16 x 16 mm, 0.8 mm ball pitch typical for this family) requires BGA escape routing with microvias or via-in-pad on the outer rows. Segment the PCB with dedicated power planes for the core rail and I/O rails, and place bulk decoupling at the ball field per TI's C2000 hardware design guidelines. Plan the escape fanout before routing high-speed buses such as EMIF, since EMIF signal integrity degrades quickly with stub lengths on BGA breakout layers.
Dual-core C2000 devices use multiple supply rails (core, I/O, analog) that require defined power-up sequencing; violating sequencing can latch up or stress the device. Estimate the total budget as the sum of core plus I/O plus analog rail currents from the datasheet electrical characteristics - a 200 MHz dual-core part drawing on the order of several hundred milliamps is typical, but verify exact figures in the TMS320F2837xD datasheet tables before sizing the power tree. Use a supervisor or TI PMIC sequencer for reliable multi-rail ordering.
Migrating from the older TMS320F28335 (as discussed on the TI E2E forum) is not a drop-in exercise: pinout, peripheral registers, and clocking differ substantially, so budget firmware porting time and use TI's migration guides. Also, when substituting the TMS320F28379S for the 'D' variant on the same PCB, verify peripheral-by-peripheral equivalence - pin compatibility does not guarantee identical analog and CLB feature sets, and code assuming second-core availability will fail if recompiled for different assumptions.
