CY62138FV30LL-45ZXIT datasheet by Cypress Semiconductor

CY62138FV30LL-45ZXIT Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62138FV30LL-45ZXIT 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. Also, ensure that the power supply ramps up and down slowly to prevent voltage spikes.
• What is the maximum clock frequency for this SRAM?
  The maximum clock frequency for the CY62138FV30LL-45ZXIT is 45 MHz, but it can be operated at lower frequencies as well.
• How do I ensure data integrity during power-down or brownout conditions?
  The CY62138FV30LL-45ZXIT has a built-in power-down feature that retains data as long as the VCC supply is above 2V. However, it's recommended to use an external power-down detector or supervisor circuit to ensure data integrity during power-down or brownout conditions.
• Can I use this SRAM in a 3.3V system?
  Yes, the CY62138FV30LL-45ZXIT is compatible with 3.3V systems, but ensure that the input signals are within the recommended voltage range of 2.2V to 3.6V.
