The recommended power-on sequence is to power up the core voltage (VDD_CORE) first, followed by the I/O voltage (VDD_MPU) and then the DDR voltage (VDD_DDR). This ensures proper power-up and prevents damage to the device.
To optimize the DDR memory interface, ensure that the DDR clock frequency is set correctly, and the DDR voltage (VDD_DDR) is within the recommended range. Also, use the recommended DDR timing parameters and ensure that the DDR memory is compatible with the device.
The maximum operating temperature range for the AM3892BCYG120 is -40°C to 105°C. However, it's recommended to operate the device within the recommended temperature range of 0°C to 90°C for optimal performance and reliability.
To implement secure boot on the AM3892BCYG120, use the device's built-in security features such as the Trusted Execution Environment (TEE) and the Secure Boot mechanism. This ensures that the device boots securely and prevents unauthorized access to the system.
The maximum current draw for the AM3892BCYG120 depends on the operating frequency and voltage. However, the typical current draw is around 1.5A for the core voltage (VDD_CORE) and 0.5A for the I/O voltage (VDD_MPU) at a frequency of 1GHz.
