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.
To optimize the DDR2 memory interface, ensure that the memory clock frequency is set to 133 MHz or lower, and use a memory module with a CAS latency of 3 or lower. Additionally, adjust the memory timing parameters, such as tRAS, tRCD, and tRP, to optimize performance.
The maximum operating temperature range for the DM3725CBPA 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.
To configure the EMIF for NAND flash memory, set the EMIF mode to asynchronous mode, and configure the NAND flash timing parameters, such as the clock frequency, read latency, and write latency, according to the NAND flash memory datasheet.
The recommended method for debugging the DM3725CBPA is to use the XDS560v2 emulator, which provides real-time debugging capabilities and allows for debugging of the ARM Cortex-A8 processor and other peripherals.
