CY7C128A-25DMB datasheet by Cypress Semiconductor

CY7C128A-25DMB Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for CY7C128A-25DMB?
  The maximum operating temperature range for CY7C128A-25DMB is -40°C to +85°C.
• How do I handle power-up and power-down sequencing for CY7C128A-25DMB?
  It is recommended to power up VCC before applying clock and input signals, and to power down VCC last. Additionally, ensure that the power supply ramps up and down slowly to prevent voltage spikes.
• What is the recommended termination scheme for CY7C128A-25DMB?
  Cypress recommends using a 50-ohm termination resistor on the output pins to prevent signal reflections and ensure signal integrity.
• Can I use CY7C128A-25DMB in a 3.3V system?
  Yes, CY7C128A-25DMB is compatible with 3.3V systems, but ensure that the input signals are within the recommended voltage range of 2.2V to 3.6V.
• How do I handle clock signal integrity for CY7C128A-25DMB?
  Use a high-quality clock source with a low jitter and ensure that the clock signal is properly terminated to prevent signal degradation.
