CY7C1381D-133AXC datasheet by Cypress Semiconductor

CY7C1381D-133AXC Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY7C1381D-133AXC has an operating temperature range of 0°C to 70°C (commercial temperature range) and -40°C to 85°C (industrial temperature range).
• How do I implement a self-refresh mode to reduce power consumption?
  To implement self-refresh mode, assert the SREF input low and ensure that the clock is stopped. This will reduce power consumption to a minimum. However, note that the device will not retain data in self-refresh mode.
• What is the maximum clock frequency supported by this device?
  The CY7C1381D-133AXC supports a maximum clock frequency of 133 MHz.
• How do I handle data bus turnaround times?
  To handle data bus turnaround times, ensure that the data bus is in a high-impedance state (tri-stated) during the turnaround period. This can be achieved by asserting the OE# (output enable) signal low.
• What is the purpose of the ZZ pin?
  The ZZ pin is used to put the device in a sleep mode, which reduces power consumption. When the ZZ pin is asserted low, the device enters a low-power state, and all internal clocks are stopped.
