CY7B991V-5JIT datasheet by Cypress Semiconductor

CY7B991V-5JIT Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CY7B991V-5JIT can operate at?
  The CY7B991V-5JIT can operate at clock frequencies up to 200 MHz.
• How do I implement a FIFO (First-In-First-Out) buffer using the CY7B991V-5JIT?
  To implement a FIFO buffer, connect the data outputs (Q) to the data inputs (D) and use the clock enable (CE) and read/write enable (R/W) signals to control the data flow.
• What is the maximum depth of the CY7B991V-5JIT?
  The CY7B991V-5JIT has a maximum depth of 2,048 bits (256 x 8-bit words).
• Can I use the CY7B991V-5JIT as a RAM?
  Yes, the CY7B991V-5JIT can be used as a RAM, but it is not a traditional RAM as it has a limited number of writes (typically 100,000 to 1 million) before the device starts to degrade.
• How do I handle the power-up and power-down sequences for the CY7B991V-5JIT?
  During power-up, ensure that the chip enable (CE) and write enable (WE) signals are held high until the power supply has stabilized. During power-down, ensure that the CE and WE signals are held low to prevent unwanted writes.
