CY15B104QN-50SXA - Infineon

CY15B104QN-50SXA Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CY15B104QN-50SXA?
  The recommended operating voltage range for CY15B104QN-50SXA is 2.7V to 3.6V, as specified in the datasheet. However, it's essential to note that the device can tolerate a voltage range of 2.3V to 3.7V, but with reduced performance and reliability.
• How do I ensure data integrity and prevent data corruption during power-down or power-up cycles?
  To ensure data integrity, it's crucial to follow the power-down and power-up sequence recommended in the datasheet. Additionally, consider implementing a voltage supervisor or a power-on reset circuit to ensure the device is properly initialized and configured before accessing the memory.
• What is the maximum clock frequency supported by CY15B104QN-50SXA?
  The maximum clock frequency supported by CY15B104QN-50SXA is 104 MHz, as specified in the datasheet. However, it's essential to consider the system's noise margin, signal integrity, and power consumption when operating at higher frequencies.
• Can I use CY15B104QN-50SXA in a system with a 5V power supply?
  No, CY15B104QN-50SXA is not designed to operate with a 5V power supply. The device's maximum rating is 3.7V, and operating it above this voltage can cause permanent damage or affect its reliability. Consider using a voltage regulator or level shifter to ensure the device operates within its recommended voltage range.
• How do I handle the HOLD pin during read and write operations?
  The HOLD pin is used to pause the current operation and allow the device to enter a low-power state. During read and write operations, the HOLD pin should be kept low (active low). When the HOLD pin is asserted high, the device will pause the current operation and enter a low-power state, reducing power consumption.
