CY7C2670KV18-550BZXI datasheet by Cypress Semiconductor

CY7C2670KV18-550BZXI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY7C2670KV18-550BZXI has an industrial temperature range of -40°C to +85°C, and a commercial temperature range of 0°C to +70°C.
• 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 (CLK = 0). The device will then enter a low-power state, reducing power consumption.
• What is the maximum clock frequency supported by this device?
  The CY7C2670KV18-550BZXI supports a maximum clock frequency of 550 MHz.
• How do I handle data bus turnaround times when switching between read and write operations?
  To ensure data bus turnaround times, insert a minimum of one clock cycle between read and write operations. This allows the bus to settle and prevents data corruption.
• What is the recommended termination scheme for the DDR2 interface?
  Cypress recommends using an ODT (On-Die Termination) scheme for the DDR2 interface, which is integrated into the device. This scheme provides improved signal integrity and reduces reflections.
