- Industrial temperature range (vs TMS320F28034PNS)
Design Notes
The TMS320F28034PNT requires a 3.3V I/O supply and a 1.8V core supply. Use a low-dropout regulator (LDO) like the TPS7A4700 to generate the 1.8V core from the 3.3V rail. Place 100nF decoupling capacitors close to each VDD and VDDIO pin, and a 10uF bulk capacitor on the main supply. Ensure the core supply is stable and noise-free to prevent erratic behavior.
For the LQFP-80 package, use a 4-layer PCB with dedicated power and ground planes. Route the JTAG signals (TCK, TMS, TDI, TDO) with controlled impedance and keep them short to avoid signal integrity issues. Place the crystal oscillator (X1/X2) close to the MCU with load capacitors as specified in the datasheet. Avoid routing high-speed signals near the crystal to prevent noise coupling.
A common mistake is forgetting to connect the VREGENZ pin (if present) or not providing the correct voltage to the VDD pins. Also, ensure the ADC reference pins are properly decoupled with a 10uF capacitor. When using the CLA, ensure the memory regions are correctly partitioned in the linker command file to avoid conflicts. Always verify the boot mode pins (GPIO84-87) are set correctly for the desired boot source.
