Design Notes
The TMS320F2812 requires separate core (1.8V/1.9V) and I/O (3.3V) supplies. Proper power-up sequencing is critical: the core voltage should be applied before or simultaneously with the I/O voltage to avoid latch-up. Use low-dropout regulators (LDOs) with appropriate current ratings, and place 100nF decoupling capacitors close to each VDD and VDDIO pin. A bulk capacitor (10uF) on each supply rail is recommended. Refer to TI's power management application notes for detailed guidance.
For the 176-pin LQFP package, ensure adequate ground plane and thermal vias under the exposed pad (if present) to dissipate heat. Route high-speed signals (e.g., EMIF, JTAG) with controlled impedance and minimize trace lengths. Keep analog and digital grounds separate and connect at a single point to reduce noise. Place the crystal oscillator close to the X1/X2 pins and keep the trace short. Follow the layout guidelines in the TMS320F2812 datasheet (SPRS174) for optimal performance.
A common pitfall is incorrect configuration of the PLL and clock source. The TMS320F2812 can use an external crystal or oscillator; ensure the PLL settings match the input frequency to avoid overclocking. Also, the flash wait states must be configured correctly for the core speed to prevent read errors. Additionally, the JTAG interface should be properly terminated (e.g., pull-up resistors on TMS and TDI) to ensure reliable debugging. Refer to the datasheet and TI application notes for initialization sequences.
