CY7C1480BV33-167AXI datasheet by Cypress Semiconductor

CY7C1480BV33-167AXI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY7C1480BV33-167AXI has an operating temperature range of 0°C to 70°C (commercial grade) and -40°C to 100°C (industrial grade).
• How do I implement the correct termination for the DDR3 interface?
  The CY7C1480BV33-167AXI requires a 50-ohm termination resistor on the DDR3 interface. Additionally, the board design should ensure that the signal traces are impedance-controlled and matched to minimize signal reflections.
• What is the recommended power-up sequence for this device?
  The recommended power-up sequence is to apply VCC first, followed by VCCQ, and then the clock signal. This ensures that the device powers up correctly and minimizes the risk of latch-up or damage.
• How do I handle the ZQ pin on this device?
  The ZQ pin is an internal impedance calibration pin. It should be connected to VCC through a 1-kohm resistor and a 0.01-uF capacitor in parallel. This ensures that the device's internal impedance calibration circuitry operates correctly.
• What is the maximum clock frequency supported by this device?
  The CY7C1480BV33-167AXI supports clock frequencies up to 167 MHz.
