CY29946AXI Frequently Asked Questions (FAQ)

  • The recommended power-up sequence is to apply VCC first, followed by VCCIO, and then the clock signal. This ensures proper initialization and prevents latch-up conditions.

  • To configure the CY29946AXI for DDR3 memory interface, set the MRS (Memory Reference Signal) pin to '1' and use the DDR3-specific settings for the memory controller. Refer to the Cypress Semiconductor application note AN54427 for detailed configuration guidelines.

  • The CY29946AXI supports frequencies up to 133 MHz, but the actual frequency limit depends on the specific application, PCB design, and signal integrity. It's recommended to consult the datasheet and perform signal integrity analysis to determine the maximum frequency for your specific design.

  • To implement clock domain crossing with the CY29946AXI, use the built-in CDC logic and follow the guidelines provided in the Cypress Semiconductor application note AN54427. This includes using the CDC registers, synchronizing clock domains, and ensuring proper metastability resolution.

  • The JTAG pins on the CY29946AXI are used for boundary scan testing, debugging, and programming. They allow for access to the device's internal registers and facilitate debugging and testing of the device and the surrounding circuitry.
