CY62138FLL-45ZSXI datasheet by Cypress Semiconductor

CY62138FLL-45ZSXI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62138FLL-45ZSXI 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 device?
  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 input signals are stable before applying VCC.
• What is the maximum clock frequency for this SRAM?
  The maximum clock frequency for the CY62138FLL-45ZSXI is 45 MHz, but it can operate at lower frequencies as well.
• How do I interface this SRAM with a microcontroller or processor?
  The CY62138FLL-45ZSXI has a standard asynchronous SRAM interface, which can be easily interfaced with most microcontrollers or processors using a simple bus interface. Ensure that the microcontroller or processor can provide the required clock frequency and control signals.
• What is the latency of this SRAM?
  The CY62138FLL-45ZSXI has a latency of 45 ns, which is the time it takes for the device to output data after receiving a read request.
