CY62256NLL-55ZXA datasheet by Cypress Semiconductor

CY62256NLL-55ZXA Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62256NLL-55ZXA can operate from -40°C to 85°C (industrial temperature range) and from 0°C to 70°C (commercial temperature range).
• How do I handle power-up and power-down sequences for this SRAM?
  The CY62256NLL-55ZXA requires a stable VCC supply before applying clock and input signals. During power-down, the device should be in a standby mode (CE high) to minimize power consumption.
• What is the maximum clock frequency supported by this SRAM?
  The CY62256NLL-55ZXA supports a maximum clock frequency of 55 MHz.
• How do I ensure data integrity during power failures or brownouts?
  The CY62256NLL-55ZXA does not have built-in data retention or backup capabilities. To ensure data integrity, consider using external power-fail detection and backup power sources, or implement data backup and restore mechanisms in your system design.
• Can I use this SRAM in a 3.3V system?
  Yes, the CY62256NLL-55ZXA is compatible with 3.3V systems, but ensure that the VCC supply voltage is within the recommended range of 3.0V to 3.6V.
