The recommended power-on sequence is to apply power to the DVDD and CVDD pins first, followed by the IOVDD pins. This ensures that the internal voltage regulators are powered up correctly.
The clocking system on the DM369 can be configured using the PLL (Phase-Locked Loop) and clock divider registers. The PLL can be configured to generate a clock frequency of up to 720 MHz, and the clock divider registers can be used to divide this frequency down to the desired clock speed for the CPU, peripherals, and interfaces.
The maximum operating temperature range for the DM369 is -40°C to 85°C. However, it's recommended to operate the device within a temperature range of 0°C to 70°C for optimal performance and reliability.
The DM369 has a DDR2 memory interface that can be implemented using the EMIF (External Memory Interface) module. The EMIF module provides a 16-bit or 32-bit data bus and supports DDR2 memory speeds of up to 400 MHz. The DDR2 memory interface can be configured using the EMIF registers and requires external components such as DDR2 memory devices, resistors, and capacitors.
The DM369's video processing subsystem supports up to 1080p resolution at 60 frames per second. It also supports other resolutions such as 720p, VGA, and QVGA, and can handle various video formats including H.264, MPEG-4, and JPEG.
