CY7C2665KV18-550BZI datasheet by Cypress Semiconductor

CY7C2665KV18-550BZI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY7C2665KV18-550BZI has an operating temperature range of 0°C to 70°C (commercial grade) and -40°C to 100°C (industrial grade).
• 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. The device will enter a low-power state, and the internal refresh will be enabled.
• What is the maximum clock frequency supported by this device?
  The CY7C2665KV18-550BZI supports a maximum clock frequency of 550 MHz.
• How do I handle errors during write operations?
  The device provides a write error flag (WRF) that is set high in case of a write error. The system can detect this flag and take corrective action, such as retrying the write operation.
• What is the latency for read and write operations?
  The read latency is 2-3-2-2 (tCL-tRCD-tRP-tRAS) and the write latency is 2-3-2-2 (tCL-tWR-tRP-tRAS) for DDR3 mode, and 5-5-5-15 (tCL-tRCD-tRP-tRAS) for DDR2 mode.
