CY62256VNLL-70ZXCT datasheet by Cypress Semiconductor

CY62256VNLL-70ZXCT Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62256VNLL-70ZXCT can operate from -40°C to 85°C.
• How do I handle power-up and power-down sequences for this device?
  The device requires a stable VCC supply before applying clock and input signals. During power-down, ensure that VCC is reduced to 0V before removing clock and input signals.
• What is the maximum clock frequency supported by this SRAM?
  The CY62256VNLL-70ZXCT supports clock frequencies up to 70 MHz.
• How do I ensure data integrity during power-down and power-up cycles?
  Use a voltage supervisor or a power-on reset circuit to ensure that the device is properly initialized during power-up, and that data is not corrupted during power-down.
• Can I use this SRAM in a system with multiple voltage domains?
  Yes, but ensure that the voltage levels are within the recommended operating range, and that proper level shifting or voltage translation is used to interface with other voltage domains.
