CY7C1049CV33-12ZSXA datasheet by Cypress Semiconductor

CY7C1049CV33-12ZSXA Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY7C1049CV33-12ZSXA has an industrial temperature range of -40°C to +85°C, making it suitable for use in a wide range of applications.
• How do I handle power-up and power-down sequencing for this device?
  It is recommended to power up the VCCQ pin (output clock) before the VCC pin (core voltage) and power down the VCC pin before the VCCQ pin to ensure proper operation and prevent latch-up.
• What is the recommended termination scheme for the output clock signal?
  The output clock signal should be terminated with a 50-ohm resistor to VCCQ or a 25-ohm resistor to VCCQ/2 to ensure signal integrity and prevent reflections.
• Can I use this device in a system with a different clock frequency?
  Yes, the CY7C1049CV33-12ZSXA is a programmable device that can be configured to operate at different clock frequencies. However, the maximum clock frequency is 133 MHz, and the device must be re-programmed to operate at a different frequency.
• How do I ensure data integrity and prevent data corruption during power-down or power-up?
  It is recommended to use a power-on reset (POR) circuit to ensure that the device is properly reset during power-up, and to use a brown-out detector (BOD) to detect power-down and prevent data corruption.
