EP9315-CBZ datasheet by Cirrus Logic

EP9315-CBZ Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the EP9315-CBZ?
  The recommended power-up sequence is to apply power to the core voltage (VDDCORE) first, followed by the I/O voltage (VDDIO). This ensures that the internal voltage regulators are powered up correctly.
• How do I configure the EP9315-CBZ for low-power operation?
  To configure the EP9315-CBZ for low-power operation, set the Power Management Unit (PMU) registers to enable the low-power modes. Additionally, reduce the clock frequency, disable unused peripherals, and use the dynamic voltage and frequency scaling (DVFS) feature to optimize power consumption.
• What is the maximum clock frequency supported by the EP9315-CBZ?
  The maximum clock frequency supported by the EP9315-CBZ is 333 MHz. However, the actual clock frequency may be limited by the specific application and system design.
• How do I implement a custom boot loader on the EP9315-CBZ?
  To implement a custom boot loader on the EP9315-CBZ, use the Boot Loader Development Kit (BLDK) provided by Cirrus Logic. The BLDK includes tools and documentation to help you create a custom boot loader that meets your specific requirements.
• What is the maximum amount of external memory supported by the EP9315-CBZ?
  The EP9315-CBZ supports up to 64 MB of external memory, including flash and SDRAM. However, the actual amount of memory supported may be limited by the specific application and system design.
