The recommended power-on sequence is to power up the core voltage (VDD_CORE) first, followed by the I/O voltage (VDD_IO). This ensures that the internal voltage regulators are properly enabled and the device boots up correctly.
To optimize the DDR2 memory interface, ensure that the memory clock frequency is set to the maximum supported frequency (166 MHz), and use the recommended timing parameters for the specific DDR2 memory module being used. Additionally, implement proper signal integrity and routing guidelines to minimize signal degradation.
The DM369's VPU supports up to 1080p resolution at 60 frames per second (fps) for H.264 and MPEG-4 encoding and decoding. For JPEG encoding and decoding, the maximum resolution is 4224x3168 at 30 fps.
Implement a reliable and efficient boot process by using a boot loader that can handle different boot modes (e.g., NAND, NOR, UART), and ensure that the boot loader is configured to correctly initialize the device's peripherals and memory interfaces. Additionally, use a secure boot mechanism to prevent unauthorized access to the device.
The DM369 has a maximum junction temperature (TJ) of 90°C. To ensure reliable operation, implement proper thermal management techniques such as heat sinks, thermal interfaces, and airflow management. Monitor the device's temperature using the on-chip temperature sensor and adjust the system design accordingly.
