Key Differentiators
- Lower flash memory for cost optimization (vs TMS320F280049-Q1)
- C variant for faster motor control development (vs TMS320F280040C-Q1)
- Automotive qualification with same performance (vs TMS320F280040 (non-Q1))
Design Notes
Power supply decoupling is critical for the TMS320F280040-Q1. Place 100 nF and 10 uF capacitors close to the VDD and VREG pins to minimize noise. The core runs at 100 MHz and requires a stable supply. Ensure the ground plane is continuous under the MCU to reduce inductance and enhance signal integrity.
For analog inputs, use proper PCB layout to reduce noise coupling. Keep the signal traces short and use shielded routing. The PGAs and SDFM need careful grounding. Use star grounding and separate analog and digital ground planes if possible. Connect the analog ground pin directly to the analog ground plane.
Take thermal design into account, especially in automotive applications. The device's junction temperature should remain within operating limits. Use a thermal pad on the PCB and provide adequate copper area for heat dissipation. If using multiple high-power drivers, consider forced air cooling or heatsinks.
