CY7C25652KV18-500BZC datasheet by Cypress Semiconductor

CY7C25652KV18-500BZC Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY7C25652KV18-500BZC 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 CY7C25652KV18-500BZC 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 CY7C25652KV18-500BZC supports a maximum clock frequency of 500 MHz.
• How do I handle the ZQ pin, and what is its purpose?
  The ZQ pin is an output impedance calibration pin. It should be connected to VSS through a 10 kΩ resistor to ensure proper output impedance calibration. This pin is used to calibrate the output impedance of the device to match the system impedance.
• What is the latency of this device, and how does it affect my system design?
  The CY7C25652KV18-500BZC has a latency of 5-5-5, which means it takes 5 clock cycles for the device to respond to a read request, 5 clock cycles to write data, and 5 clock cycles to respond to a write request. This latency should be considered when designing the system to ensure proper data transfer and synchronization.
