CY62256NLL-55ZXIT datasheet by Cypress Semiconductor

CY62256NLL-55ZXIT Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62256NLL-55ZXIT 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 recommended clock frequency for this SRAM?
  The maximum clock frequency for the CY62256NLL-55ZXIT is 55 MHz, but it can operate at lower frequencies as well.
• 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 levels?
  Yes, but ensure that the voltage levels are within the recommended operating range of 4.5V to 5.5V, and that voltage transitions are smooth and glitch-free.
