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 that the internal voltage regulators are powered up in the correct order.
The clocking system on the AM3894CCYG120 can be configured using the Clock Domain Control (CDC) module. The CDC module allows you to configure the clock sources, clock frequencies, and clock domains. You can use the TI-provided clock configuration tool or write your own code to configure the CDC module.
The maximum operating temperature range for the AM3894CCYG120 is -40°C to 105°C. However, the device can be operated at a reduced frequency and voltage at temperatures above 85°C.
The AM3894CCYG120 has a built-in Secure Boot feature that allows you to implement secure boot mechanisms. You can use the TI-provided Secure Boot software development kit (SDK) to implement secure boot on your device. The SDK provides tools and documentation to help you create a secure boot image and configure the device for secure boot.
The AM3894CCYG120 supports up to 16 GB of DDR3/DDR3L memory and has a maximum memory bandwidth of 12.8 GB/s.
