CY62148BLL-70ZI datasheet by Cypress Semiconductor

CY62148BLL-70ZI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62148BLL-70ZI can operate from -40°C to +85°C, making it suitable for industrial and automotive applications.
• How do I handle power-up and power-down sequences for this SRAM?
  It's recommended to power up the VCC supply before the VSS supply, and power down the VSS supply before the VCC supply to prevent latch-up and ensure proper operation.
• What is the maximum clock frequency for this SRAM?
  The CY62148BLL-70ZI can operate at clock frequencies up to 70 MHz, making it suitable for high-speed applications.
• How do I ensure data retention during power-down?
  To ensure data retention during power-down, the VCC supply should be reduced to 2V or less, and the CE# and OE# pins should be held high to prevent data corruption.
• What is the typical standby current for this SRAM?
  The typical standby current for the CY62148BLL-70ZI is around 1mA, making it suitable for battery-powered applications.
