CY62128BNLL-55SXI datasheet by Cypress Semiconductor

CY62128BNLL-55SXI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62128BNLL-55SXI operates over an industrial temperature range of -40°C to +85°C.
• How do I handle power-up and power-down sequences for this device?
  The device has a power-up and power-down sequence that must be followed to ensure proper operation. 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 maximum clock frequency for the CY62128BNLL-55SXI is 55 MHz.
• How do I interface this SRAM with a microcontroller or processor?
  The CY62128BNLL-55SXI has a standard asynchronous SRAM interface that can be easily interfaced with most microcontrollers or processors. The device requires a 3.3V power supply and has a byte-wide data bus. The chip enable (CE), output enable (OE), and write enable (WE) signals must be controlled by the microcontroller or processor to access the SRAM.
• Is this SRAM device radiation-hardened or suitable for space applications?
  No, the CY62128BNLL-55SXI is not a radiation-hardened device and is not suitable for space applications. It is a commercial-grade device intended for use in industrial and commercial applications.
