CY7C25652KV18-450BZXC datasheet by Cypress Semiconductor

CY7C25652KV18-450BZXC Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY7C25652KV18-450BZXC 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 CY7C25652KV18-450BZXC 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 internal refresh circuitry.
• What is the maximum clock frequency supported by this device?
  The CY7C25652KV18-450BZXC 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 to match the impedance of the system. It should be connected to VDDQ through a resistor (RQ) to set the output impedance.
• What is the latency of this device, and how does it affect my system design?
  The CY7C25652KV18-450BZXC has a latency of 5-5-5, which means it takes 5 clock cycles to write data, 5 clock cycles to read data, and 5 clock cycles to access the data. This latency should be considered when designing the system to ensure that the memory access timing is met.
