TMS320F28032PAGT - C2000 32-bit 60MHz 64KB Flash MCU | TI
MPN: TMS320F28032PAGT ✓ Hoạt độngTMS320F28032PAGT Tóm tắt
A microcontroller unit (MCU) integrates a processor core, memory, and peripherals on a single chip, forming the lowest layer of the embedded processing hierarchy that spans MCUs, digital signal processors (DSPs), and application processors. The C2000 Piccolo family sits at the intersection of MCU integration and DSP performance: it is code-compatible with previous C28x-based code while packing real-time control peripherals into low pin-count devices.
Key features of the TMS320F28032 include the C28x fixed-point CPU with Control Law Accelerator (CLA), a high-speed 4.6 MSPS on-chip ADC, and highly integrated control peripherals such as ePWM modules that make it well suited to closed-loop power conversion. The 60 MHz core delivers deterministic single-cycle 32-bit multiply performance that general-purpose MCUs cannot match in control loops.
Architecturally, the device is built on high-performance static CMOS technology and executes from 64 KB of embedded flash with JTAG-based flash programming, supporting in-field firmware updates. The peripheral set, real-time interrupt (RTI) structure, and rapid interrupt response of the C28x pipeline allow control-loop cycle times measured in single-digit microseconds.
Typical applications include digital power supplies, solar micro-inverters, LED lighting drivers, motor control (BLDC, PMSM, stepper), and industrial power-tool battery chargers, where the integrated ePWM, ADC, and comparator resources replace external analog control circuitry.
When designing with this device, budget flash headroom for the CLA control routines and verify that the -40C to +85C operating range matches the end-product environment; the 10x10 TQFP also requires careful decoupling of the VDDIO rail for clean ADC performance.

Ứng dụng tiêu biểu
TMS320F28032PAGT phù hợp cho 6 Áp dụngs: Digital Power Supplies, Solar Micro-Inverters, Brushless DC and PMSM Motor Control, LED Lighting Drivers, Power Tool Battery Chargers, Industrial Control and Sensing Nodes.
Digital Power Supplies
The TMS320F28032PAGT fits digitally controlled AC/DC and DC/DC power supplies because its 60 MHz C28x core closes voltage and current loops at switching frequencies of 100 kHz to 500 kHz with deterministic latency, while the 12-bit 4.6 MSPS ADC samples the output and inductor current synchronously with the PWM period. Integrated ePWM modules provide complementary outputs with programmable dead-band, trip-zone fault shutdown, and high-resolution period control, replacing analog compensation networks with firmware. Placed as the sole controller with a 3.3V rail, the device implements peak-current-mode or average-current-mode control entirely in software; the trade-off is that firmware validation replaces a fixed analog control law, so protective trip-zone hardware must be configured in addition to software limits.

Solar Micro-Inverters
In solar micro-inverter designs, the TMS320F28032PAGT performs both maximum power point tracking (MPPT) and grid-synchronized current injection on one chip: the C28x core runs the MPPT algorithm while a second control loop locks the output current to the grid voltage with phase-locked-loop firmware. The 4.6 MSPS ADC samples panel voltage/current and grid voltage within each switching cycle, and ePWM outputs drive the interleaved boost and DC/AC stages with complementary, dead-banded PWM. The 64 KB flash accommodates MPPT, PLL, and protection code for a single-panel inverter, and the -40C to +85C range matches rooftop environmental requirements; designers planning grid-code expansion across regions should verify remaining flash headroom before finalizing the BOM.

Brushless DC and PMSM Motor Control
The TMS320F28032PAGT is a strong controller for three-phase BLDC and PMSM drives. Its ePWM modules generate six complementary signals with hardware dead-band, and the trip-zone inputs shut off PWM within one PWM cycle on overcurrent faults detected by the on-chip comparators - critical protection the C2000 architecture implements without CPU intervention. The 60 MHz core executes field-oriented control with current-loop periods in the tens of microseconds, sampling phase currents through the 4.6 MSPS ADC. For sensorless operation, sliding-mode or flux observers fit in the 64 KB flash. A key consideration is ADC trigger alignment: ePWM-triggered sampling of shunt currents must occur at the PWM counter zero/period points to avoid switching noise, which the on-chip ADC/PWM synchronization hardware directly supports.
Được đề xuất
LED Lighting Drivers
For high-power LED drivers requiring precise dimming and power-factor correction, the TMS320F28032PAGT controls both the PFC front end and the constant-current LED stage with a single 60 MHz C28x device. The ePWM modules produce dimming PWM with high resolution for flicker-free operation down to deep dimming ratios, while the 4.6 MSPS ADC samples LED current for closed-loop regulation with accuracy better than analog-only solutions. Digital control enables adaptive schemes - temperature-based current derating and smart dimming profiles - that are impractical with fixed analog controllers. The 64 KB flash holds PFC, CC/CV regulation, and communication code for DALI or PWM-dimming interfaces; verify the -40C to +85C ambient rating against the luminaire's internal thermal environment, which can exceed 85C in sealed fixtures.

Power Tool Battery Chargers
Lithium-ion power-tool chargers benefit from the TMS320F28032PAGT's combination of control performance and analog integration. The C28x core implements CC/CV charging profiles, cell balancing supervision, and junction-temperature-aware charge-rate derating, while the 4.6 MSPS ADC continuously monitors pack voltage, current, and thermistor inputs. ePWM drives the buck or flywheel converter stage with adaptive frequency and dead-band, and trip-zone hardware provides cycle-by-cycle overcurrent protection independent of software timing - an important safety property for charging high-energy packs. The 64 KB flash is sufficient for the charge state machine and fault logging. The device also supports communication with the pack's fuel gauge or ID EEPROM over an integrated serial port for authentication and charge parameter negotiation.

Industrial Control and Sensing Nodes
As a general industrial embedded controller, the TMS320F28032PAGT provides DSP-grade processing in a compact 64-pin TQFP for nodes that combine sensing and local control - for example, pump/valve controllers, power-quality monitors, and closed-loop process sensors. The 60 MHz C28x core handles filtering (IIR/FIR), FFT-based analysis, and a control loop simultaneously, while the 4.6 MSPS ADC acquires sensor channels without an external converter. Integrated serial ports connect to industrial transceivers (RS-485 via external PHY, or isolated links via digital isolators), and the -40C to +85C rating suits unconditioned cabinets. Design consideration: allocate flash carefully, as 64 KB is modest for applications that add protocol stacks on top of control firmware - the 128 KB F28035PAGT drop-in provides an upgrade path on the same PCB.

Ghi chú thiết kế
Provide a solid ground plane under the 10x10 mm 64-TQFP and place 0.1 uF ceramic decoupling capacitors within 2-3 mm of each VDDIO pin, plus bulk 10 uF at the supply entry. The ADC reference and VDDIO rails are sensitive: route analog sense lines away from ePWM switching nets and consider a small ferrite between digital supply and analog supply feeds. The thermal pad is not present on the PAG package, so junction heat exits through the leads - keep adjacent copper areas free of thermally sensitive parts.
Verify the exact ordering suffix when sourcing: PAGT (this part, -40C to +85C tray) differs from PAGQ and PAGS variants in quality grade or packaging, and ETEI/Xecor comparison pages show frequent mix-ups between F28032 and F28033/35 flash sizes. Firmware built for the F28032 will not use the CLA present on the F28033/35/34, and code compiled with the wrong device header may configure nonexistent peripherals. Always recompile against the C2000Ware header for the installed device and re-run the flash API erase check after migrating between family members.
Configure ADC sampling to be triggered by the ePWM counter (zero or period event) rather than free-running software triggers, so current-shunt sampling lands in the quiet window between switching edges. This uses the on-chip ADC/PWM synchronization and removes switching transients from control-loop measurements. For JTAG programming, keep the TRST/TDI/TDO traces short and add series termination near the emulator connector; floating JTAG pins in production units can cause spurious test-logic entry, so pull TRST appropriately per the F2803x datasheet reset guidance.
