CY62128BLL-55ZRI datasheet by Cypress Semiconductor

CY62128BLL-55ZRI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62128BLL-55ZRI 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 CY62128BLL-55ZRI can operate at clock frequencies up to 55 MHz, making it suitable for high-speed applications.
• How do I handle bus contention and data corruption during power-up and power-down?
  To prevent bus contention and data corruption, ensure that the chip select (CS) and output enable (OE) signals are driven high during power-up and power-down. This will tri-state the outputs and prevent data corruption.
• What is the typical standby current consumption of this SRAM?
  The typical standby current consumption of the CY62128BLL-55ZRI is around 2 mA, making it suitable for battery-powered applications.
