Key Features
- 90 MHz C28x 32-bit CPU with hardware FPU enabling single-cycle 32-bit floating-point operations for precise real-time control loops
- Dedicated Control Law Accelerator (CLA) co-processor running independently at 90 MHz to offload time-critical algorithms from the main CPU
- 256 KB Flash and onboard ADC plus DMA support fast closed-loop sampling and deterministic code execution for motor drives and inverters
Applications
TMS320F28069UPZT is targeted at high-frequency power conversion designs including digital power supplies, solar inverters, and motor drive controllers where precise closed-loop control at 90 MHz reduces switching losses and improves efficiency. The CLA co-processor runs independent control algorithms without CPU overhead, making it ideal for multi-axis servo drives and UPS systems. Its integrated ADC and DMA streamline sensor acquisition in battery management systems and grid-tie inverters.

Frequently Asked Questions
How does the CLA co-processor in TMS320F28069UPZT improve real-time control loop performance?
The Control Law Accelerator (CLA) in TMS320F28069UPZT runs independently at 90 MHz with its own instruction set, executing closed-loop PID or MPPT algorithms without interrupting the main C28x CPU. This dual-core approach reduces control loop latency to under 1 µs, allowing switching frequencies above 200 kHz in digital power supplies.
What ADC resolution and sampling rate does TMS320F28069UPZT offer for current and voltage sensing?
The TMS320F28069UPZT integrates a 12-bit ADC with simultaneous sampling capability and conversion times as fast as 160 ns per sample. Multiple ADC channels can be triggered synchronously with PWM events, enabling precise current and voltage sensing within a single switching cycle for closed-loop power control.
Which motor drive topologies benefit most from TMS320F28069UPZT at 90 MHz?
TMS320F28069UPZT at 90 MHz with hardware FPU efficiently implements field-oriented control (FOC) for 3-phase PMSM and BLDC motors, space vector modulation (SVM) for inverter stage control, and sensored or sensorless encoder feedback loops that require floating-point trigonometric computations to be completed within each 50 µs control cycle.
How much program storage does TMS320F28069UPZT provide and is it sufficient for IEC 61508 safety firmware?
TMS320F28069UPZT offers 256 KB of on-chip Flash plus 1 KB of OTPROM for configuration data. For functional safety firmware conforming to IEC 61508 SIL 2, the 256 KB Flash typically accommodates the application, safety monitor stack, and diagnostic routines, though complex multi-axis implementations may require code size optimization or external serial Flash.
