CY621282BNLL-70SXET datasheet by Cypress Semiconductor

CY621282BNLL-70SXET Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY621282BNLL-70SXET 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 CY621282BNLL-70SXET is 70 MHz, but it can operate at lower frequencies as well.
• Can I use this SRAM in a 3.3V system?
  Yes, the CY621282BNLL-70SXET is compatible with 3.3V systems, but ensure that the input signals are within the recommended voltage range of 2.2V to 3.6V.
• How do I handle bus contention and data corruption during power-up and power-down?
  To prevent bus contention and data corruption, use a pull-up or pull-down resistor on the data lines, and ensure that the chip select (CS) and output enable (OE) signals are properly controlled during power-up and power-down.
