CY14B104LA-BA45XI datasheet by Cypress Semiconductor

CY14B104LA-BA45XI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY14B104LA-BA45XI 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) and a write protect signal (WP) to prevent accidental writes, and following the write timing specifications in the datasheet.
• What is the device's behavior during a power failure or brownout condition?
  The CY14B104LA-BA45XI has a built-in power-fail detection circuit that automatically resets the device during a power failure or brownout condition, and the device will retain its data until the power supply is restored.
