TMS320DM6467CZUT datasheet by Texas Instruments

TMS320DM6467CZUT Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DM6467?
  The recommended power-up sequence is to apply power to the core voltage (VDD) first, followed by the I/O voltage (VDDIO), and then the clock signal. This ensures that the internal voltage regulators are powered up correctly and the device is properly initialized.
• 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 EMIF clock frequency is within the recommended range. Additionally, use the EMIF calibration feature to optimize the memory interface timing.
• What is the maximum operating temperature range for the DM6467?
  The maximum operating temperature range for the DM6467 is -40°C to 85°C. However, it's recommended to operate the device within the industrial temperature range of -40°C to 70°C for optimal performance and reliability.
• How do I implement DDR2 memory interface with the DM6467?
  To implement a DDR2 memory interface with the DM6467, use the EMIF module and configure it for DDR2 mode. Ensure that the DDR2 memory is properly connected to the EMIF pins, and the memory timing parameters are set correctly. Additionally, use the DDR2 calibration feature to optimize the memory interface timing.
• What is the purpose of the TWL (Texas Instruments Wideband Low-power) interface?
  The TWL interface is a low-power, high-speed interface used for connecting peripherals such as cameras, displays, and storage devices. It's a proprietary interface developed by Texas Instruments and is used to reduce power consumption and improve system performance.
