Frequently Asked Questions
What CPU speed does the TMS320F280040PMQR run at and how does this benefit real-time control loops?
The TMS320F280040PMQR C28x core operates at up to 100 MHz, executing control loop iterations in under 10 µs including ADC sampling, PID computation, and PWM update. This processing speed is sufficient for switching frequencies up to 100 kHz in digital power supply designs and field-oriented control of AC motors at 20 kHz PWM. The CLA co-processor adds additional parallel processing capacity without impacting main CPU scheduling latency.
Which digital power and motor control peripherals are integrated in the TMS320F280040PMQR?
The TMS320F280040PMQR integrates multiple ePWM (enhanced PWM) modules with dead-band generation and trip-zone protection for motor and power converter control, eCAP (enhanced capture) units for speed and position measurement, and 12-bit ADC channels for real-time current and voltage feedback. The ePWM modules support high-resolution PWM (HRPWM) with sub-nanosecond duty cycle adjustment, critical for precision DC-DC converter regulation at switching frequencies up to 200 kHz.
How does the TMS320F280040PMQR compare to other C2000 devices for a three-phase inverter design?
The TMS320F280040PMQR (F28004x family) is positioned between entry-level F2806x devices and higher-end F2838x devices in the C2000 portfolio. It provides sufficient ePWM channels for a 3-phase inverter with 6 PWM outputs, 12-bit ADC for current and voltage sensing across 3 phases, and a CLA co-processor for field-oriented control algorithms. For designs requiring higher floating-point performance or more peripherals, the F2837xD dual-core variant offers Floating Point Unit (FPU) and TMU acceleration at higher cost.
What package does the TMS320F280040PMQR use and what pin count does this support?
The TMS320F280040PMQR is packaged in a QFP (Quad Flat Package) format, the PMQR suffix indicating a specific pin count and package variant within the QFP family. QFP packages for C2000 microcontrollers typically range from 64 to 100 pins, providing access to the full set of GPIO, ADC, PWM, and communication peripheral pins. The flat package with peripheral gull-wing leads is compatible with standard SMT reflow soldering at temperatures up to 260°C and supports high pin count at moderate PCB density.
