The CY7C1314KV18-250BZXI has an operating temperature range of -40°C to +85°C.
The CY7C1314KV18-250BZXI 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.
The recommended power-up sequence for the CY7C1314KV18-250BZXI is to apply power to the VDDQ pins first, followed by the VDD pins. This ensures that the internal voltage regulators are powered up correctly.
The ZQ pin on the CY7C1314KV18-250BZXI is an internal impedance calibration pin. It should be connected to a 240-ohm resistor to ground to enable internal impedance calibration.
The maximum current rating for the VDD pins is 1.5A, and for the VDDQ pins is 2.5A. Ensure that the power supply and PCB design can handle these current requirements.
