CY7C1475BV25-133BGXI datasheet by Cypress Semiconductor

CY7C1475BV25-133BGXI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY7C1475BV25-133BGXI 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 implement a self-refresh mode to reduce power consumption?
  To implement self-refresh mode, you need to assert the SREF pin low and ensure that the clock is stopped. This will put the device in a low-power state, reducing power consumption. Refer to the datasheet for specific timing requirements.
• What is the maximum clock frequency supported by this device?
  The CY7C1475BV25-133BGXI supports a maximum clock frequency of 133 MHz, making it suitable for high-speed applications.
• How do I handle data bus turnaround times when switching between read and write operations?
  To handle data bus turnaround times, you need to ensure that the data bus is tri-stated before switching between read and write operations. This can be done by asserting the OE# pin high and then switching the direction of the data bus.
• What is the purpose of the ZZ pin, and how do I use it?
  The ZZ pin is a sleep mode pin that allows the device to enter a low-power state. To use it, assert the ZZ pin low to put the device in sleep mode, and assert it high to return to normal operation.
