CY62256NLL-55ZXI datasheet by Cypress Semiconductor

CY62256NLL-55ZXI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62256NLL-55ZXI 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 CY62256NLL-55ZXI supports clock frequencies up to 55 MHz.
• How do I ensure data retention during power-down?
  To ensure data retention, VCC must be reduced to 2V or less within 10 ms of removing the clock signal. This allows the internal voltage regulator to shut down, preserving data.
• What is the typical standby current consumption of this device?
  The typical standby current consumption of the CY62256NLL-55ZXI is 10 mA.
