TMS320F28034QPNTQ1 Übersicht
A digital signal controller (DSC) combines the compute throughput of a DSP with the peripheral integration and ease of use of a microcontroller. Within the power-management hierarchy, the C2000 family sits at the level of real-time control MCUs: semiconductor -> microcontroller (MCU) -> digital signal controller -> C2000 real-time control MCU -> TMS320F28034-Q1. DSCs are the industry-standard choice for closed-loop control of power conversion and motor drive systems.
Key features include the Control Law Accelerator (CLA), an independent 32-bit floating-point math coprocessor that offloads control-loop computations from the main C28x core; high-resolution PWM (HRPWM) peripherals for fine duty-cycle resolution in power converters; a 12-bit ADC with fast conversion times for current sensing; and code compatibility with all previous C28x devices, protecting software investments. Internal 1.8V/3.3V supply operation simplifies power-tree design.
Architecturally, the F2803x Piccolo generation couples the C28x fixed-point core with the CLA, on-chip flash, SRAM, ePWM, eCAP, eQEP, SCI, SPI, I2C, and CAN modules in low pin-count packages, providing a high level of analog and control integration.
Typical applications include automotive electric power steering, HEV/EV auxiliary inverters, on-board battery chargers, solar micro-inverters, and industrial motor drives such as FOC-controlled PMSM and BLDC systems, where 60 MHz real-time loop execution and precise PWM are essential.
Design consideration: when migrating from the commercial TMS320F28034 to this Q1 variant, verify that the temperature rating and AEC-Q100 qualification requirements of your end application align, and confirm pin-level compatibility before PCB reuse.

Typische Anwendungen
TMS320F28034QPNTQ1 ist geeignet für 6 Anwendungs: Automotive Electric Power Steering, On-Board Battery Charger (OBC), Industrial Motor Drives (PMSM/BLDC FOC), Solar Micro-Inverters, HEV/EV Auxiliary Inverters and DC-DC, Digital Power Supplies (Server/Telecom).
Automotive Electric Power Steering
The TMS320F28034QPNTQ1 executes field-oriented motor control for EPS assist motors using its 60 MHz C28x core and CLA coprocessor, which offloads floating-point FOC loops for deterministic sub-100us control periods. AEC-Q100 qualification meets automotive OEM sourcing requirements, while HRPWM enables smooth low-speed torque feel through fine duty-cycle resolution. The 12-bit ADC samples phase currents via shunt or Hall sensors, and CAN supports steering-angle communication with the vehicle ECU, per TI automotive reference designs.
Empfohlen
On-Board Battery Charger (OBC)
In HEV/EV on-board chargers, the F28034QPNTQ1 runs interleaved PFC and LLC/phase-shifted full-bridge control loops. The CLA handles floating-point compensation at 60 MHz while ePWM modules generate interleaved gate waveforms with HRPWM fine resolution that reduces ripple and eases EMI filter design. AEC-Q100 rating satisfies automotive qualification, and the 12-bit ADC digitizes voltage/current feedback for accurate charge termination. Dual-loop execution within one device lowers BOM count versus discrete controllers.
Empfohlen
Industrial Motor Drives (PMSM/BLDC FOC)
For servo drives and BLDC motors, the 60 MHz C28x plus CLA implements sensorless FOC with sliding-mode or SMO observers, while eQEP modules process incremental encoder feedback for closed-loop position control. HRPWM provides fine PWM resolution that minimizes current ripple and audible noise at low speeds. On-chip flash of 128 KB holds control firmware plus communication stacks (SCI, SPI, CAN), enabling a single-chip drive controller with deterministic interrupt latency for tight speed-loop bandwidths.
Empfohlen
Solar Micro-Inverters
The F28034QPNTQ1 controls MPPT and grid-tied inverter stages, running maximum-power-point tracking in the main C28x core while the CLA executes the current-control loop at 60 MHz. HRPWM reduces output current THD by improving effective PWM resolution at high switching frequencies, and the 12-bit ADC provides panel-voltage/current and grid feedback sampling. Code compatibility across the C2000 family lets designers reuse proven inverter firmware, shortening time to certification for grid-interconnection standards.
Empfohlen
HEV/EV Auxiliary Inverters and DC-DC
Auxiliary converters (12V from HV bus) and low-power inverters in vehicles benefit from the F28034QPNTQ1 deterministic C28x architecture: PWM trip-zone hardware provides cycle-by-cycle overcurrent protection without CPU intervention, critical for fault containment in automotive power systems. AEC-Q100 qualification and TI's automotive flow meet OEM component requirements, while CAN communication enables diagnostic reporting. The 128 KB flash stores multiple control profiles selectable at runtime for multi-mode converter operation.
Empfohlen
Digital Power Supplies (Server/Telecom)
High-density server and telecom power stages use the F28034QPNTQ1 for adaptive voltage positioning, phase current balancing, and PMBus-style host control. The CLA executes per-phase current sharing loops while the C28x core manages telemetry over SCI/I2C, and HRPWM improves transient response resolution at 100kHz-plus switching frequencies. Nonlinear PID and frequency-dithering firmware fits within the 128 KB flash, delivering digital power flexibility - configurable loop gains and sequencing - that analog controllers cannot match.

Wichtigste Unterscheidungsmerkmale

- Maximum F2803x flash in same footprint (vs. TMS320F28033PNT)
- CLA floating-point accelerator (vs. TMS320F28032PNT)
Designhinweise
The F2803x uses an internal VREG to generate the 1.8V core from the 3.3V VDDIO supply. Place a 1.3uF minimum ceramic capacitor on VDD (core rail) close to the pin per the TMS320F2803x datasheet power-supply section, and do not drive the VDD rail externally when the internal regulator is enabled. Sequence VDDIO before or with VDD per TI datasheet requirements to avoid latch-up during power-up.
For the 80-pin LQFP, place 0.1uF decoupling capacitors at each VDDIO/VDD pin pair within 2mm of the pin, plus one bulk 10uF per supply domain. The XCLKOUT and JTAG (TRST, TMS, TDI, TCK) traces should be kept short with series termination on TRST to prevent emulation issues. Refer to TI C2000 hardware design guide (SPRABV4) for LQFP fanout practice.
When substituting other F2803x family members (e.g., F28033 with 64KB flash), the linker command file flash sectors differ - re-map .text and .econst sections or the code will not fit. Also, HRPWM calibration registers must run the HR self-calibration routine in software at startup; skipping this causes coarse PWM steps. Verify ADC calibration (ADC_cal) is called before sampling.
Compliance-Informationen
Q1 suffix indicates TI automotive flow with AEC-Q100 qualification. RoHS and lead-free status per TI product page; REACH and halogen-free declarations require TI quality portal confirmation.
