CY7C1441AV25-133BZXI datasheet by Cypress Semiconductor

CY7C1441AV25-133BZXI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY7C1441AV25-133BZXI 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 the self-refresh mode to reduce power consumption?
  To implement self-refresh mode, the device must be in the idle state, and the SREF pin must be driven low. The device will then enter self-refresh mode, reducing power consumption. Refer to the datasheet for specific timing and voltage requirements.
• What is the maximum clock frequency supported by this device?
  The CY7C1441AV25-133BZXI supports a maximum clock frequency of 133 MHz, making it suitable for high-speed applications.
• How do I handle the ZQ pin, and what is its purpose?
  The ZQ pin is an output impedance calibration pin. It should be connected to VSS through a 10 kΩ resistor to ensure proper output impedance calibration. This pin is used to calibrate the output impedance of the device to match the system requirements.
• What is the purpose of the JTAG pins, and how do I use them?
  The JTAG pins (TCK, TDI, TDO, and TMS) are used for boundary scan testing and debugging. They can be used to test the device and perform debugging operations. Refer to the IEEE 1149.1 standard for more information on JTAG testing and debugging.
