Key Differentiators
- Automotive qualification (AEC-Q100) (vs TMS320F28035PNS)
- Larger memory (128 KB flash, 20 KB SRAM) (vs TMS320F28034PNQ)
- Control Law Accelerator (CLA) (vs TMS320F28034PNQ)
Design Notes
Ensure a clean 3.3V supply with adequate decoupling capacitors (e.g., 100nF and 10uF) placed close to the VDD and VDDIO pins. Use separate analog and digital grounds to minimize noise coupling into the ADC.
For the LQFP-80 package, use a 4-layer PCB with a solid ground plane. Route high-speed signals away from the crystal oscillator and ADC inputs. Follow TI's layout guidelines in the datasheet for optimal performance.
Do not exceed the absolute maximum ratings for supply voltage (3.3V Β±10%). Ensure the boot mode pins are correctly configured to avoid unintended boot from flash. Use the watchdog timer to prevent system hangs.
