CY62256VNLL-70SNXC datasheet by Cypress Semiconductor

CY62256VNLL-70SNXC Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62256VNLL-70SNXC 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-70SNXC 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-70SNXC supports clock frequencies up to 70 MHz.
• How do I interface this SRAM with a microcontroller or processor?
  The CY62256VNLL-70SNXC can be interfaced with a microcontroller or processor using a standard synchronous SRAM interface. The chip select (CS), output enable (OE), and write enable (WE) signals should be connected to the corresponding pins on the microcontroller or processor.
• What is the latency of this SRAM?
  The CY62256VNLL-70SNXC has a latency of 2 clock cycles for read operations and 1 clock cycle for write operations.
