The recommended power-up sequence is to apply power to the DVDD and AVDD pins simultaneously, followed by the CVDD pin. This ensures proper power-up and minimizes the risk of latch-up or damage to the device.
To minimize power consumption, configure the device to use the lowest possible clock frequency, disable unused peripherals, and use the power-down modes (e.g., idle, standby, or shutdown) when the device is not in use. Additionally, use the power management registers to control the voltage and frequency of the CPU and peripherals.
The maximum clock frequency supported by the DM3725CUSD100 is 1 GHz. However, the actual clock frequency may be limited by the specific application, board design, and thermal considerations.
Implement a reliable boot process by using a secure boot mechanism, such as booting from a trusted source (e.g., a secure boot ROM or a trusted flash memory). Ensure that the boot process is fault-tolerant and can recover from errors or corruption. Additionally, use checksums or digital signatures to verify the integrity of the boot code and data.
The DM3725CUSD100 has a maximum junction temperature (TJ) of 125°C. Ensure that the device is properly heat-sinked and that the thermal design of the board is adequate to dissipate heat. Monitor the device temperature and throttle the clock frequency or shut down the device if the temperature exceeds the recommended limits.
