- Wider operating temperature range option (vsTMS320F2808PZQ)
- Fixed-point core optimized for real-time control (vsTMS320F28335PZA)
Catatan Desain
The TMS320F2808PZA requires separate power supplies for core (1.8V) and I/O (3.3V). Use low-dropout regulators (LDOs) with low noise and good transient response. Place decoupling capacitors (100nF and 10uF) close to each VDD and VDDIO pin. Ensure the core supply ramps up before or simultaneously with the I/O supply to avoid latch-up. Refer to the datasheet for power sequencing requirements.
For the 100-pin LQFP package, ensure proper PCB layout with a solid ground plane and adequate thermal relief. Use a 4-layer board with dedicated power and ground planes to minimize noise. Place the crystal oscillator and JTAG connector close to the MCU, with short traces. Follow the manufacturer's recommended footprint and stencil design for reliable soldering.
A common pitfall is neglecting the JTAG interface during layout. Always bring out the JTAG pins (TMS, TCK, TDI, TDO) to a standard header for debugging and firmware updates. Also, ensure the 128-bit security key/lock is properly configured to avoid locking yourself out. Use the watchdog timer to prevent system hangs, and verify the ADC reference voltage for accurate conversions.
