TMS320C6474FCUN datasheet by Texas Instruments

TMS320C6474FCUN Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the TMS320C6474FCUN?
  The recommended power-up sequence is to apply power to the core voltage (VDD) first, followed by the input/output voltage (VDDIO). This ensures that the internal voltage regulators are powered up correctly.
• How do I configure the EMIF (External Memory Interface) for optimal performance?
  To configure the EMIF for optimal performance, ensure that the memory timing parameters are set correctly, and the memory clock frequency is within the recommended range. Also, use the EMIF calibration feature to optimize the memory interface.
• What is the maximum frequency of the DDR3 interface?
  The maximum frequency of the DDR3 interface is 1066 Mbps, but it can be overclocked to 1333 Mbps with careful signal integrity design and validation.
• How do I implement a secure boot mechanism on the TMS320C6474FCUN?
  To implement a secure boot mechanism, use the device's built-in security features such as the Secure Boot Loader (SBL) and the Trusted Execution Environment (TEE). These features provide a secure environment for booting and executing code.
• What is the maximum amount of external memory that can be connected to the TMS320C6474FCUN?
  The maximum amount of external memory that can be connected to the TMS320C6474FCUN is 2 GB of DDR3 memory, divided into two 1-GB channels.
