CY7C1512AV18-250BZC datasheet by Cypress Semiconductor

CY7C1512AV18-250BZC Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY7C1512AV18-250BZC has an industrial temperature range of -40°C to +85°C, making it suitable for a wide range of applications.
• How do I implement a self-refresh mode to reduce power consumption?
  To enter self-refresh mode, assert the Chip Enable (CE) signal low and the Clock Enable (CKE) signal high. This reduces power consumption by putting the device into a low-power state.
• What is the recommended termination scheme for the DDR2 interface?
  Cypress recommends using On-Die Termination (ODT) with a 50-ohm resistor in series with a 22-ohm resistor to the VTT supply for optimal signal integrity and noise reduction.
• Can I use this device in a DDR3 system?
  No, the CY7C1512AV18-250BZC is a DDR2 SDRAM and is not compatible with DDR3 systems. It operates at a different voltage and has different signal timings, making it incompatible with DDR3 systems.
• How do I handle refresh commands in a system with multiple SDRAM devices?
  When using multiple SDRAM devices, refresh commands should be staggered to avoid simultaneous refreshes, which can cause system performance issues. Staggering refresh commands ensures that only one device is refreshed at a time, minimizing system impact.
