TMS320F28332PTPS 概要
A digital signal controller (DSC) combines the high-throughput arithmetic of a digital signal processor with the peripheral integration and interrupt responsiveness of a microcontroller. Within the power-management hierarchy, the C28x Delfino family sits at the high end of TI's real-time control MCU portfolio, optimized for fast closed-loop control algorithms in motor drives, power conversion, and industrial automation systems.
Key differentiating features include the 32-bit C28x CPU with single-cycle multiply-accumulate, an FPU that offloads floating-point math and shortens control-loop software overhead, a 12-bit ADC with up to 16 channels for precise analog acquisition, high-resolution ePWM peripherals for power-stage control, and multiple communication interfaces (SCI, SPI, McBSP, CAN, I2C).
Technically, the device runs from a 1.8 V core supply (1.71 V to 1.89 V) with 3.3 V I/O, over a -40C to +125C industrial temperature range. The EMIF enables external memory or FPGA expansion, and 52 KB of on-chip SRAM supports fast control variables and data buffers.
Typical applications include industrial motor drives, solar inverters and renewable energy converters, digital power supplies (LLC, totem-pole PFC), and traction control systems. The high-speed ADC and ePWM modules enable precise, low-latency control, while the CAN interface supports robust communication in harsh environments.
Design consideration: properly decouple the 1.8 V core and 3.3 V I/O rails, and solder the exposed thermal pad to the ground plane per the datasheet layout guidelines to optimize thermal and electrical performance.

主な用途
TMS320F28332PTPS の用途: 6 件s: Industrial Motor Drives, Solar Inverters and Renewable Energy Converters, Digital Power Supplies (LLC and Totem-Pole PFC), Automotive Traction and Auxiliary Control, Test and Measurement Instruments, Industrial Automation and PLC I/O Modules.
Industrial Motor Drives
The TMS320F28332PTPS fits industrial motor drives because its 100 MHz C28x core with hardware FPU executes field-oriented control (FOC) inner loops at switching frequencies of 10-20 kHz with ample margin, while the 12-bit ADC samples phase currents with low latency for precise torque control. High-resolution ePWM modules drive IGBT/SiC gate stages with fine duty resolution, reducing current ripple in PMSM and induction motor applications. In a typical servo drive, the FPU shortens FOC computation versus fixed-point IQmath implementations, freeing CPU cycles for position supervision and communication. The CAN interface provides robust fieldbus connectivity, and the -40C to +125C temperature range suits cabinet and integrated drive environments.
おすすめ
Solar Inverters and Renewable Energy Converters
The TMS320F28332PTPS is well suited to solar inverters and MPPT converters because its 100 MHz FPU-equipped core runs MPPT search algorithms and grid-synchronization (PLL) routines concurrently while the 12-bit ADC acquires DC bus, grid voltage, and current feedback. High-resolution ePWM outputs control boost, LLC, and inverter power stages, and the EMIF can attach external memory for event logging. Because the Delfino family executes control and protection logic on one chip, response to grid faults occurs within microseconds. The -40C to +125C industrial rating and RoHS-compliant 176-pin HLQFP package support outdoor power electronics enclosures, and TI reference designs for string inverters accelerate certification-driven development cycles.
おすすめ
Digital Power Supplies (LLC and Totem-Pole PFC)
The TMS320F28332PTPS fits digital power supplies because high-resolution ePWM peripherals generate phase-shifted and complementary PWM with fine granularity for LLC resonant converters and totem-pole PFC stages, while the 12-bit ADC closes current loops with minimal sample-to-output delay. The 100 MHz C28x core with FPU implements nonlinear control laws, feed-forward compensation, and adaptive dead-time algorithms in floating point, simplifying tuning versus fixed-point code. On-chip comparators and trip zones provide hardware-level overcurrent protection independent of software latency. Its 128 KB flash accommodates housekeeping, PMBus/communication stacks, and protection tables, making it a strong fit for server power and telecom rectifier designs.
おすすめ
Automotive Traction and Auxiliary Control
For traction and auxiliary inverter control, the TMS320F28332PTPS architecture (shared with the qualified TMS320F28335PTPQ variant) provides the FPU-accelerated field-oriented control and fast interrupt response required by EV motor controllers. The 12-bit ADC synchronized to ePWM triggers samples phase currents at carrier frequency, and hardware trip zones shut gates off within microseconds on fault detection. The EMIF supports external memory for functional-safety logging, and CAN networks integrate with vehicle buses. Designs targeting production vehicles should select the Q-grade family members, using this commercial-grade part for prototyping, while the identical 176-pin HLQFP footprint allows a direct drop-in migration path between grades.
おすすめ
Test and Measurement Instruments
The TMS320F28332PTPS serves test and measurement applications such as electronic loads, power analyzers, and programmable supplies. Its 100 MHz core with FPU performs real-time RMS computation, waveform analysis, and control-loop regulation simultaneously, while the 12-bit ADC digitizes multiple channels (up to 16) for measurement acquisition. The EMIF interface connects external SRAM or FPGAs for high-speed data buffering, and McBSP/SPI links support front-end data converters. The 176-pin HLQFP (PTP) package exposes abundant GPIO for relay control, front-panel interfaces, and trigger I/O. Deterministic interrupt latency of the C28x core ensures consistent sampling intervals, which is critical for measurement repeatability and calibration stability across the -40C to +125C range.
おすすめ
Industrial Automation and PLC I/O Modules
In industrial automation, the TMS320F28332PTPS handles deterministic control tasks in PLCs, motion modules, and distributed I/O. The C28x core's fast interrupt response services hard-real-time control cycles, while SCI, SPI, I2C, and CAN interfaces connect sensors, encoders, and fieldbus transceivers. The FPU simplifies implementation of PID and feed-forward algorithms for process loops, and 128 KB flash stores control firmware, parameter sets, and diagnostics. The EMIF allows memory expansion for logging in harsh environments, and the industrial -40C to +125C temperature rating suits cabinet and machine-mounted electronics. Its pin-compatible family lets one PCB serve multiple module variants by populating different F2833x flash densities for firmware tiers.

設計ノート
The TMS320F28332PTPS requires a dual-rail supply: 1.8 V core (1.71 V to 1.89 V) and 3.3 V I/O. Use a dedicated LDO or buck for the core rail with at least 10 uF bulk plus 0.1 uF per supply pin ceramic decoupling placed within 2 mm of the pins. Observe the datasheet power sequencing requirements between the rails. Estimated: core current at 100 MHz is typically on the order of 200-300 mA per family power tables - size the core regulator with margin and verify against the TI power estimation spreadsheet for your specific clock configuration.
The exposed pad on the underside of the 176-HLQFP (PTP) package is not optional - solder it to a grounded copper pour with an array of thermal vias per the datasheet layout guidelines. Estimated: even at moderate loads the C28x core at 100 MHz dissipates several hundred milliwatts, and without pad connection the thermal resistance of the package rises significantly, increasing junction temperature in sealed industrial enclosures. A solid ground pad also improves signal integrity by lowering ground inductance for the ADC and ePWM pins.
Keep the ADC analog inputs away from ePWM and clock switching traces; route each ADC channel with its own guard ground trace and filter with an RC (e.g., 50 ohm / 100 pF as a starting point) sized to the sampling capacitor charge requirement in the datasheet. Use an external crystal per TI clock guidelines with proper load capacitors, and reserve XCLKOUT for debug. For EMIF bus routing, match trace lengths on the data/address bus and add series termination to control reflections at 100 MHz operation.
Flash programming requires the 3.3 V flash supply within tolerance and correct wait-state configuration for the CPU frequency - misconfigured wait states cause erratic code execution at 100 MHz. Do not leave unused GPIO floating; configure internal pull-ups/downs per TI's recommendations in the datasheet terminal functions table. Also note that family members sharing this footprint differ in flash size and clock speed: code compiled for a 150 MHz F28335 must have its clock configuration adjusted before running on the 100 MHz F28332.
コンプライアンス情報
RoHS compliant and lead-free per LCSC listing (C1344145). AEC-Q100 qualification applies to Q-suffix family variants (e.g., TMS320F28335PTPQ), not this standard part. REACH, halogen-free, and conflict-minerals status should be confirmed on the TI quality portal.
