CY62148ELL-55SXA datasheet by Cypress Semiconductor

CY62148ELL-55SXA Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62148ELL-55SXA can operate from -40°C to 85°C (industrial temperature range) and from -40°C to 125°C (extended temperature range) with reduced performance.
• How do I handle power-up and power-down sequences for this SRAM?
  The CY62148ELL-55SXA has a power-up and power-down sequence that must be followed to ensure data integrity. The power supply voltage (VCC) must be applied before the chip enable (CE) and output enable (OE) signals. During power-down, the CE and OE signals must be disabled before the VCC is removed.
• What is the maximum clock frequency for this SRAM?
  The CY62148ELL-55SXA has a maximum clock frequency of 55 MHz.
• How do I handle bus contention and data corruption during simultaneous read and write operations?
  The CY62148ELL-55SXA has a built-in feature to prevent bus contention and data corruption during simultaneous read and write operations. The device uses a transparent Deselect mode, where the output buffers are turned off during write operations, and the input buffers are turned off during read operations.
• What is the typical standby current consumption of this SRAM?
  The typical standby current consumption of the CY62148ELL-55SXA is around 1 mA at 55 MHz and 3.3V VCC.
