MIMX8QX2AVOFZAC - NXP

MIMX8QX2AVOFZAC Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the MIMX8QX2AVOFZAC?
  The recommended power-on sequence is to power up the VDD_HIGH first, followed by VDD_LOW, and then the core voltage (VDD_CORE). This ensures that the internal voltage regulators are properly enabled and the device boots up correctly.
• How do I configure the DDR memory interface on the MIMX8QX2AVOFZAC?
  The DDR memory interface on the MIMX8QX2AVOFZAC can be configured using the DDR Controller (DDRC) registers. The recommended configuration is to use the DDR4 mode with a clock frequency of 1066 MHz and a data width of 32 bits. The DDR calibration process should also be performed to ensure reliable operation.
• What is the maximum operating temperature range for the MIMX8QX2AVOFZAC?
  The maximum operating temperature range for the MIMX8QX2AVOFZAC is -40°C to 105°C. However, it's recommended to operate the device within the industrial temperature range of -40°C to 85°C for optimal performance and reliability.
• How do I implement secure boot on the MIMX8QX2AVOFZAC?
  Secure boot on the MIMX8QX2AVOFZAC can be implemented using the Boot ROM and the Fuse Box. The Boot ROM verifies the authenticity of the boot loader and the operating system, while the Fuse Box stores the secure boot keys and configuration. NXP provides a Secure Boot SDK and documentation to guide the implementation process.
• What is the maximum clock frequency for the Cortex-A35 core on the MIMX8QX2AVOFZAC?
  The maximum clock frequency for the Cortex-A35 core on the MIMX8QX2AVOFZAC is 1.2 GHz. However, the actual clock frequency may vary depending on the specific use case, thermal conditions, and power consumption requirements.
