CY62256VNLL-70ZXI datasheet by Cypress Semiconductor

CY62256VNLL-70ZXI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this SRAM?
  The CY62256VNLL-70ZXI 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 CY62256VNLL-70ZXI is 70 MHz. However, the recommended frequency is 66 MHz to ensure reliable operation.
• How do I implement a wait state in this SRAM?
  To implement a wait state, assert the WEN (Write Enable) signal low and CE (Chip Enable) signal high. This will put the device in a wait state, allowing the system to perform other tasks.
• What is the maximum current consumption of this device?
  The maximum current consumption of the CY62256VNLL-70ZXI is 220 mA at 70 MHz and 3.3V VCC.
