TMS320F28379DZWTS Overview
A microcontroller (MCU) is a single-chip computer integrating CPU, memory, and peripherals that engineers program to sense, compute, and actuate in embedded systems. Within the taxonomy, MCUs sit under microcontrollers -> embedded processors -> digital ICs -> integrated circuits -> semiconductors. The C2000 Delfino family specifically targets real-time control: motor control, digital power, and servo loops where deterministic interrupt latency and per-MIPS cost dominate the design decision.
Key specifications: 1 MB on-chip Flash (512K x 16), 204 KB SRAM, dual 200 MHz C28x cores, hardware FPU and TMU, three 12-bit ADCs at up to 3.5 MSPS each, four 16-bit ADCs (throughput to 200 ns), CMPSS (comparator/DAC subsystems), eight ePWM modules, two eQEP, three eCAP, two SDFM, USB 2.0 (host + device), CAN-FD, SPI, I2C, UART, and EMIF for external memory expansion.
Architecturally, the dual C28x cores each have their own CLA, allowing parallel execution of control loops without CPU loading. The TMU accelerates sin/cos/atan math used in transforms and observer algorithms, while the CLB enables hardware-state-machine glue logic that previously required external CPLDs. Safety diagnostics include ECC on Flash and RAM, dual watchdog timers, lockstep on CPU and CLA, and a built-in self-test (BIST).
Typical applications include industrial motor drives and multi-axis servo control, photovoltaic solar inverters and digital power conversion, electric vehicle traction inverters and onboard chargers, and renewable-energy grid-tie inverters. Industrial factory-automation controllers and PLCs leverage the deterministic CLA cores for sub-microsecond control loops.
When designing with this MCU, plan the PCB for a 337-ball NFBGA (16x16 mm, 0.8 mm pitch) - a 4-layer stackup minimum, with all power rails decoupled within 5 mm of each ball group. Use TI's C2000Ware SDK and the Code Composer Studio IDE for development; software compatibility is preserved across F2837xD, F2837xS, and F2807x pin-compatible families.

Recommended
Solar Inverters and Digital Power Conversion
The TMS320F28379DZWTS implements MPPT, grid-tie synchronization, and THD compensation in photovoltaic inverters at switching frequencies up to 200 kHz. Its hardware FPU accelerates the Park/Clark transforms and SVPWM math at line-rate, while the dual CLAs offload the per-cycle closed-loop tasks (peak current mode control, ABM-leg balancing, sync-skipping) from the main CPU. SDFM channels directly interface with sigma-delta modulators from isolated current sensors, eliminating analog signal chains. The integrated EMIF allows external FIFO memory for grid-tie waveform buffering. TI's C2000Ware digital-power library provides reference firmware that achieves >99% MPPT efficiency and <3% THD at full load.

Electric Vehicle Traction Inverters and Onboard Chargers
The TMS320F28379DZWTS targets EV traction inverters and OBCs requiring tight torque, speed, and regenerative-braking control. Its dual-core C28x architecture delivers 800 MIPS for SVPWM with simultaneous battery-state estimation (SOC, SOH). Built-in Functional Safety diagnostics - ECC on Flash/RAM, lockstep cores, dual watchdog timers - meet ASIL-B/C requirements per ISO 26262, shortening automotive qualification cycles. The 8 ePWM modules drive three-phase IGBT bridges with programmable dead-band to prevent shoot-through, while the SDFM channels accept signals from isolated current sensors in the inverter. CAN-FD enables high-speed battery-management communication.

Design Notes
The 337-ball NFBGA at 0.8 mm pitch requires a 4-layer minimum PCB stackup with laser-drilled microvia or via-in-pad capability for the inner-row balls. Per TI's ZWT package design guide, place 0402-sized decoupling capacitors (typically 100 nF + 4.7 uF pairs) within 5 mm of each power ball, and connect ground balls directly to a continuous inner ground plane using 2 vias per ball. Route all high-speed ePWM and ADC traces on the top layer with length matching within 10 mils between pairs. Use a 1 oz copper pour on outer layers for thermal dissipation, with thermal vias (8-12 mil drill, 1 mm spacing) under the central ball array to reduce theta-JA.
Estimated thermal analysis at full 1A total CPU + peripheral current draw: Pdiss = VD_CORE x I_CORE + VI/O x I_IO. The F28379D's internal core voltage (typically 1.2V) versus I/O rail (3.3V) drives most thermal dissipation. For the 337-NFBGA ZWT, TI specifies theta-JA of approximately 30 C/W on a JEDEC 2s2p test board. Estimated: at 1.5W typical application power, junction rises about 45 C above ambient - well within the -40C to +125C operating window for industrial designs. For sustained 2W+ operation, attach the central ball thermal pad to a copper thermal pour with thermal vias, or place the device on top side of board (vs bottom) to enable heatsink assembly.
Common F2837xD bring-up pitfalls: (1) TI's lockstep configuration requires the chip's BIST and CLB hardware fault injection to complete before the watchdog timer expires - leave at least 100 ms after reset for BIST completion; (2) Enabling Flash ECC before Flash is fully initialized can cause spurious single-bit errors - sequence Flash init before ECC enable; (3) The CLA requires its own unique bootloader image at address 0x10_0080 - missing this causes CLA not to start; (4) GPIO mux configuration must complete before peripheral functions are enabled, else peripherals see input from default mode; (5) Watchdog window register default is very tight - reset the window before expecting any interrupt. Reference the TI TMS320F2837xD silicon errata (document advisories) before finalizing firmware.
