CY14B104NA-BA25XIT datasheet by Cypress Semiconductor

CY14B104NA-BA25XIT Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY14B104NA-BA25XIT has an operating temperature range of -40°C to +85°C.
• How do I handle power-up and power-down sequencing for this device?
  It is recommended to power up the VCC supply before the VIO supply, and power down the VIO supply before the VCC supply to prevent latch-up conditions.
• What is the recommended PCB layout and routing for this device?
  Cypress recommends following the PCB layout and routing guidelines in the datasheet, including using a solid ground plane, minimizing signal trace lengths, and avoiding vias under the device.
• How do I implement a reliable write operation for this device?
  To ensure a reliable write operation, Cypress recommends using a write enable signal (WEN) to control the write operation, and using a write protect signal (WP) to prevent accidental writes.
• What is the device's behavior during a power failure or brownout condition?
  The CY14B104NA-BA25XIT has a built-in power-fail detection circuit that automatically resets the device during a power failure or brownout condition, preventing data corruption or loss.
