Applications
TMS320F28033PAGT is purpose-built for digital control of power electronics and motor drives, including single-phase and three-phase inverters, brushless DC motor controllers, and solar micro-inverters that demand sub-microsecond ADC-to-PWM latency. The on-chip CLA co-processor allows the main CPU to handle communication and supervisory tasks while the CLA independently executes real-time PID and field-oriented control algorithms without interrupt overhead. Industrial servo drives, UPS systems, and switched-mode power supplies benefit from the device's high-resolution PWM, fast ADC, and floating-point computation capability at 60 MHz.

Frequently Asked Questions
How does the CLA co-processor in TMS320F28033PAGT improve real-time control loop performance?
The Control Law Accelerator (CLA) is an independent 32-bit floating-point co-processor running at 60 MHz alongside the main C28x CPU. It executes control algorithms such as PID loops and Clarke-Park transforms without stealing CPU cycles, reducing control loop latency to under 1 µs and freeing the main CPU for communication, diagnostics, and supervisory tasks.
What ADC resolution and channel count does TMS320F28033PAGT provide for current and voltage sensing?
TMS320F28033PAGT integrates a 12-bit ADC with up to 16 multiplexed input channels and simultaneous sample-and-hold capability. At 60 MHz system clock, conversion time is approximately 80 ns per sample, enabling over 3 Msps effective throughput when sequencing all channels for three-phase current and voltage sensing in motor drive applications.
For a solar micro-inverter design, what is the ePWM resolution and can it achieve dead-time insertion?
TMS320F28033PAGT features high-resolution ePWM modules with 150 ps PWM resolution in HRPWM mode, enabling fine duty-cycle control at switching frequencies up to 300 kHz. The dead-band submodule supports programmable dead-time insertion from 0 ns to 16.38 µs in 10 ns steps, preventing shoot-through in H-bridge and three-phase inverter topologies.
Is TMS320F28033PAGT compatible with Texas Instruments ControlSUITE and Code Composer Studio for firmware development?
Yes, TMS320F28033PAGT is fully supported by TI's Code Composer Studio (CCS) IDE and ControlSUITE software library, which includes motor control, power conversion, and math libraries optimized for the C28x architecture. The device's JTAG interface supports real-time hardware breakpoints and variable watches during closed-loop operation, significantly reducing commissioning time in production designs.
How does TMS320F28033PAGT compare to TMS320F28027 in terms of memory and co-processor capability?
TMS320F28033PAGT provides 64 KB Flash and includes the CLA floating-point co-processor, while TMS320F28027 offers only 32 KB Flash and lacks the CLA. Both run at 60 MHz in a similar pin-compatible 38-pin LQFP package, making TMS320F28033 the preferred choice when algorithm complexity or dual-loop control requires parallel computation offloading.
