CY62256L-70SNXI datasheet by Cypress Semiconductor

CY62256L-70SNXI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62256L-70SNXI can operate from -40°C to +85°C, making it suitable for industrial and commercial 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 CY62256L-70SNXI has a maximum clock frequency of 70 MHz, making it suitable for high-speed applications.
• How do I ensure data integrity during power-down or power-up sequences?
  It's recommended to use a voltage supervisor or a power-on reset circuit to ensure that the SRAM is in a known state during power-up and power-down sequences, and to prevent data corruption.
• Can I use this SRAM in a 3.3V system?
  Yes, the CY62256L-70SNXI is compatible with 3.3V systems, but it's recommended to check the voltage tolerance and ensure that the system can provide the required voltage and current.
