CY62128ELL-45SXA datasheet by Cypress Semiconductor

CY62128ELL-45SXA Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62128ELL-45SXA can operate from -40°C to +85°C, making it suitable for industrial and automotive 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 CY62128ELL-45SXA 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 CY62128ELL-45SXA has a built-in power-down protection circuit that prevents data corruption during power-down or brownout conditions. However, it's still recommended to use an external power supervisor or voltage monitor to detect power-down conditions and initiate a controlled shutdown sequence.
• Can I use this SRAM in a system with multiple voltage domains?
  Yes, the CY62128ELL-45SXA can be used in systems with multiple voltage domains, but ensure that the voltage levels are within the recommended operating range and that the power supplies are properly isolated and decoupled.
