CY7C128A-45PC datasheet by Cypress Semiconductor

CY7C128A-45PC Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for CY7C128A-45PC?
  The maximum operating temperature range for CY7C128A-45PC is 0°C to 70°C (commercial grade) and -40°C to 85°C (industrial grade).
• How do I handle power-up and power-down sequencing for CY7C128A-45PC?
  It is recommended to power up the VCC supply before the VCCQ supply, and power down the VCCQ supply before the VCC supply to prevent latch-up and ensure proper operation.
• What is the recommended termination scheme for CY7C128A-45PC?
  The recommended termination scheme for CY7C128A-45PC is to use a 50-ohm resistor in series with the clock input (CLK) and a 50-ohm resistor in series with the data inputs (DQ) to prevent signal reflections and ensure signal integrity.
• How do I handle clock signal integrity issues with CY7C128A-45PC?
  To handle clock signal integrity issues, ensure that the clock signal has a clean and stable waveform, and use a clock signal with a rise time of less than 1 ns and a fall time of less than 1 ns. Also, use a clock signal with a frequency that is within the specified operating frequency range.
• What is the maximum clock frequency supported by CY7C128A-45PC?
  The maximum clock frequency supported by CY7C128A-45PC is 133 MHz.
