CY7C1440AV33-250AXC Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY7C1440AV33-250AXC has an operating temperature range of 0°C to 70°C (commercial grade) and -40°C to 85°C (industrial grade).
• How do I implement a self-refresh mode to reduce power consumption?
  To implement self-refresh mode, assert the SREF pin low and ensure that the clock is stopped. This mode reduces power consumption by stopping the internal clock and disabling the output buffers.
• What is the maximum clock frequency supported by this device?
  The CY7C1440AV33-250AXC supports a maximum clock frequency of 250 MHz.
• How do I handle data bus turnaround times?
  To handle data bus turnaround times, ensure that the data bus is in a high-impedance state (tri-stated) during the turnaround period to prevent data bus contention.
• What is the purpose of the ZZ pin?
  The ZZ pin is used to put the device in sleep mode, which reduces power consumption. When ZZ is asserted low, the device enters sleep mode and all internal clocks are stopped.
