CY7C1568KV18-450BZXI datasheet by Cypress Semiconductor

CY7C1568KV18-450BZXI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY7C1568KV18-450BZXI has an industrial temperature range of -40°C to +85°C, and a commercial temperature range of 0°C to +70°C.
• How do I implement a self-refresh mode to reduce power consumption?
  The CY7C1568KV18-450BZXI has a self-refresh mode that can be enabled by asserting the SREF pin low. This mode reduces power consumption by stopping the clock and disabling the output buffers.
• What is the maximum clock frequency supported by this device?
  The CY7C1568KV18-450BZXI supports a maximum clock frequency of 450 MHz.
• How do I handle the ZQ pin, and what is its purpose?
  The ZQ pin is an output impedance control pin that allows the user to adjust the output impedance of the device. It should be connected to VSS through a 1 kΩ resistor to ensure proper operation.
• What is the latency of the device, and how does it affect my system design?
  The CY7C1568KV18-450BZXI has a latency of 2.5 clock cycles for read operations and 1 clock cycle for write operations. This latency should be taken into account when designing the system to ensure proper data transfer and synchronization.
