TMS320F28032PNQ 概要
A microcontroller (MCU) is a single integrated circuit that combines a processor core, program memory, data memory, and peripheral set into one chip, forming the lowest level of the embedded-computing hierarchy: MCU -> embedded processor -> microcontroller -> semiconductor. The C2000 family from Texas Instruments specializes in real-time control, meaning the C28x core executes control-loop algorithms with deterministic interrupt latency, which general-purpose MCUs do not guarantee.
Key features include the 32-bit C28x core delivering 60 MIPS at 60 MHz, static CMOS technology, 64 KB on-chip Flash program memory, and operation from dual 1.8V and 3.3V supply domains. The Piccolo architecture packs the peripherals needed for digital power conversion and motor control - ePWM modules, high-resolution analog comparators, and 12-bit ADC - into a compact, cost-optimized pin count.
Architecturally, the TMS320F28032PNQ uses the T320C2xLP CPU core, object-compatible with the TMS320C2xx and upwardly compatible within the C28x Piccolo family, allowing code migration to larger-memory siblings such as the TMS320F28033, TMS320F28034, and TMS320F28035 without a pin-out change in the 80-LQFP package.
Typical applications include automotive motor control (BLDC, PMSM, FOC drives), solar micro-inverters and digital power supplies, and industrial traction or servo systems where AEC-Q100-grade qualification and real-time PWM control are required. The 60 MHz core closes current loops at switching frequencies well above the audible band.
Design consideration: choose the appropriate Flash-size family member early - the 80-LQFP footprint is shared, so migrating from 64 KB to 128 KB Flash is often a PCB-free swap, but watch supply sequencing across the 1.8V core and 3.3V I/O rails.

主な用途
TMS320F28032PNQ の用途: 6 件s: Automotive Motor Control (BLDC/PMSM), Digital Power Supplies and Solar Micro-Inverters, Industrial Servo and Traction Drives, Automotive Body and Auxiliary Electronics, Battery Management and 48V Systems, Networking and Communication Equipment Power.
Automotive Motor Control (BLDC/PMSM)
The TMS320F28032PNQ fits automotive motor-drive ECUs because its 60 MHz C28x core closes FOC current loops deterministically while its automotive AEC-Q100 classification and -40C to +85C range satisfy automotive module requirements. The integrated ePWM modules generate complementary dead-banded gate signals, and the on-chip 12-bit ADC samples phase currents at PWM frequency for space-vector control of BLDC and PMSM motors in pumps, fans, and actuators. Running FOC at a 16 kHz control rate consumes only a fraction of the 60 MIPS budget, leaving headroom for diagnostic state machines and CAN communication. Compared to a general-purpose MCU, deterministic interrupt latency keeps current-loop bandwidth stable across temperature and load.

Digital Power Supplies and Solar Micro-Inverters
Digital power converters need precise, glitch-free PWM with fast analog feedback - exactly the combination the TMS320F28032PNQ provides with its ePWM modules, on-chip comparators, and 12-bit ADC inside a single 80-LQFP device. In a solar micro-inverter or telecom rectifier, the 60 MHz C28x core executes phase-shifted full-bridge or totem-pole PFC control loops at 100-500 kHz switching frequencies, with the ADC triggered synchronously to PWM to cancel switching ripple from current samples. The 64 KB Flash holds the control firmware, compensation tables, and a firmware-update bootloader. Its AEC-Q100 classification also suits automotive onboard chargers exposed to harsh environments.
おすすめ
Industrial Servo and Traction Drives
Industrial servo drives demand tight speed-loop control with encoder feedback, and the TMS320F28032PNQ addresses this with its eQEP quadrature encoder inputs, eCAP capture modules, and deterministic C28x interrupt architecture. The 60 MHz core runs cascaded current/velocity/position loops at kilohertz rates while simultaneously tracking encoder counts in hardware, offloading timing-critical counting from software. The 80-LQFP 12x12 mm footprint keeps gate-driver, sensing, and communication routing compact on drive control boards. With 64 KB Flash, position-profile tables and Modbus/CAN stacks coexist with the control firmware, and the family footprint upgrade path to 128 KB F28035 removes re-layout if code grows.
おすすめ
Automotive Body and Auxiliary Electronics
Beyond traction, the TMS320F28032PNQ serves automotive auxiliary modules - HVAC blower controls, radiator-fan drivers, and electronic water pumps - where its AEC-Q100 series classification and 64 KB Flash cover both the control loop and the LIN/CAN diagnostic firmware. The 3.3V I/O domain interfaces directly to transceivers and hall sensors without level shifting, and the 12-bit ADC reads NTC temperature sensors and bus currents for protection routines. Its 60 MHz performance handles sensorless (BEMF) commutation algorithms that 8-bit MCUs cannot close reliably at low speed. XAIPART stocks memory and interface companions for these designs, simplifying single-source BOM consolidation for tier-one suppliers.
おすすめ
Battery Management and 48V Systems
In 48V mild-hybrid and energy-storage systems, the TMS320F28032PNQ acts as the pack controller executing cell-balancing supervision, contactor control, and isolation-monitoring state machines. Its 60 MHz C28x core provides the deterministic timing that contactor pre-charge sequences and fault-reaction time requirements demand, while the 12-bit ADC and on-chip comparators implement fast overcurrent trip paths in hardware independent of software. The 64 KB Flash accommodates SOC estimation algorithms (coulomb counting plus OCV correction) alongside the safety monitor. The AEC-Q100 classification and -40C to +85C rating make it suitable for under-body and engine-bay-adjacent BMS installations in passenger vehicles.
おすすめ
Networking and Communication Equipment Power
Line cards, PoE midspans, and small-cell base stations rely on digitally controlled power stages where the TMS320F28032PNQ provides the real-time PWM and telemetry management its 60 MHz C28x core executes with cycle-accurate determinism. The MCU reads output voltage/current via its 12-bit ADC, adjusts PWM duty for point-of-load converters, and reports PMBus-style telemetry over SCI/I2C. The 80-LQFP 12x12 mm package fits dense power boards between magnetics and hot-swap circuits, and AEC-Q100-grade screening provides the reliability headroom that telecom equipment expects for continuous operation. Its 64 KB Flash stores multiple converter profiles selectable at boot for platform reuse.

設計ノート
The TMS320F28032PNQ requires dual rails: 1.8V core and 3.3V I/O. Follow the TI F2803x datasheet power-up sequencing guidance - VDDIO should never lag VDD during ramp-up, or latch-up risk rises. Place a 0.1uF ceramic at every VDD/VDDIO pin pair plus 10uF bulk per rail. Estimated: a 60 MHz C28x core draws on the order of 50-100 mA, so a 150 mA LDO per rail suffices; keep the ADC analog 3.3V isolated through a ferrite bead to preserve 12-bit accuracy.
On the 80-LQFP 12x12 mm land pattern, keep the ePWM outputs to gate drivers short and matched, since dead-band edges at 100-500 kHz switching frequencies are directly distorted by trace skew. Route the JTAG (TCK, TMS, TDI, TDO) header traces under 15 cm with series 22-33 ohm resistors on TCK to control ringing with XDS100/XDS110 emulators. Decouple VDDIO pins on the solder-side of the footprint to minimize loop inductance, and provide at least one solid ground plane beneath the device.
When migrating within the F2803x family (F28032 to F28033/34/35), do not assume identical GPIO multiplexing defaults - larger-memory variants add peripherals that change some GPAMUX/GPBMUX reset states. Verify the PLL settings against the 60 MHz specification, since the input clock divider differs from F2802x parts. Also confirm CSM (code security module) key programming before mass production: unlocked Flash on returned units is a common field-failure complaint and cannot be re-secured without reflashing.
Estimated: at 60 MHz with typical I/O loading, the TMS320F28032PNQ dissipates roughly 200-350 mW. With an 80-LQFP theta_JA in the vicinity of 60-80 C/W on a standard 4-layer board, junction rise above ambient stays well under 30 C - no heatsink or thermal pad is needed. Concentrate on air flow around neighboring power stages (gate drivers, LDOs) rather than the MCU itself; the 80-LQFP exposed-lead frame is not a thermal package.
