CY62158ELL-45ZSXIT datasheet by Cypress Semiconductor

CY62158ELL-45ZSXIT Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62158ELL-45ZSXIT can operate from -40°C to 85°C.
• How do I handle power-up and power-down sequences for this device?
  The device requires a stable VCC supply before applying clock and input signals. During power-down, ensure that VCC is reduced to 0V before removing clock and input signals.
• What is the recommended clock frequency for this SRAM?
  The maximum clock frequency for the CY62158ELL-45ZSXIT is 45 MHz. However, the recommended frequency is 40 MHz to ensure reliable operation.
• How do I handle bus contention and data bus turnaround times?
  To avoid bus contention, ensure that only one device is driving the data bus at a time. For data bus turnaround times, allow at least 2-3 clock cycles for the bus to settle before accessing the SRAM.
• What is the maximum current consumption for this device?
  The maximum current consumption for the CY62158ELL-45ZSXIT is 135 mA at 45 MHz and 3.3V VCC.
