Key Differentiators
- Automotive AEC-Q100 qualification (vs TMS320F280034 (non-Q1))
- 128 KB flash with FPU/TMU/CLA (vs TMS320F280032-Q1)
- Hardware AES and CAN-FD (vs TMS320F280023-Q1)
Design Notes
For reliable operation of the TMS320F280034-Q1, decouple each VDD and VDDIO pin with 100nF ceramic capacitors placed as close to the pins as possible, and a bulk 4.7uF capacitor near the power entry. The MCU has separate analog and digital power supplies, so use ferrite beads between them to reduce noise coupling. Provide a clean 3.3V rail and maintain power-up sequencing per the datasheet.
Route the ADC input traces with ground guarding and keep them away from switching nodes to minimize noise. The oscillator and PLL pins need a dedicated ground area and short traces. For the LQFP-48 package, use a solid ground pour on the bottom layer to enhance thermal dissipation and reduce inductance. Follow the TI recommended layout guidelines in the TMS320F28003x datasheet.
Do not leave boot configuration pins floating, as this may cause unexpected boot behavior. Configure the TRST pin appropriately to avoid unintentional test mode. Ensure flash wait states are set for 120MHz operation; otherwise, incorrect flash reads can occur. Refer to the TMS320F28003x datasheet for the recommended flash wait-state and PLL configuration values.
