- 80-pin LQFP package (vs TMS320F28069PZT)
Design Notes
The TMS320F28069UPNT has an internal voltage regulator that requires external capacitors on the VREG pins as specified in the datasheet. Use a 3.3V supply for VDDIO and ensure proper decoupling with 100nF capacitors near each power pin. The core voltage is generated internally, so no external core supply is needed.
For the 80-pin LQFP package, ensure adequate ground plane and thermal vias under the exposed pad (if present) to improve heat dissipation. Keep high-speed signal traces short and avoid routing near crystal oscillator pins. Follow TI's layout guidelines for the C2000 family to minimize noise and EMI.
Do not exceed the absolute maximum ratings for VDD and VDDIO. Ensure the boot mode pins are configured correctly to avoid unintended boot from flash or SCI. Also, verify that the JTAG pins are not left floating during operation, as this can cause unexpected behavior.
Compliance Information
