CY62256VNLL-70SNXE datasheet by Cypress Semiconductor

CY62256VNLL-70SNXE Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62256VNLL-70SNXE 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 CY62256VNLL-70SNXE requires a controlled power-up sequence to ensure proper operation. The power supply voltage (VCC) should be applied before the clock signal (CLK), and the chip select (CS) should be held high during power-up. During power-down, the clock signal should be stopped before the power supply voltage is removed.
• What is the maximum clock frequency supported by this SRAM?
  The CY62256VNLL-70SNXE supports clock frequencies up to 70 MHz.
• How do I interface this SRAM with a microcontroller or processor?
  The CY62256VNLL-70SNXE has a standard asynchronous SRAM interface, which can be easily interfaced with most microcontrollers or processors. The SRAM's address, data, and control signals (CS, WE, OE) should be connected to the corresponding signals of the microcontroller or processor.
• What is the latency of this SRAM?
  The CY62256VNLL-70SNXE has a latency of 10 ns (maximum) for read and write operations.
