CY14B104M-ZSP25XI datasheet by Cypress Semiconductor

CY14B104M-ZSP25XI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The CY14B104M-ZSP25XI 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 any latch-up conditions.
• What is the recommended PCB layout and routing for this device?
  It is recommended to follow a 4-layer PCB stack-up with a solid ground plane, and to route the clock and data signals as close to the device as possible to minimize noise and signal degradation.
• How do I implement a reliable reset circuit for this device?
  A reliable reset circuit can be implemented using a voltage supervisor IC, such as the CY1147, which can detect power-on reset and brown-out conditions, and provide a clean reset signal to the device.
• What are the considerations for using this device in a high-reliability or automotive application?
  In high-reliability or automotive applications, it is recommended to follow Cypress's guidelines for device qualification, and to consider factors such as device derating, thermal management, and fault tolerance.
