W9725G6KB-25 Frequently Asked Questions (FAQs)

  • The maximum operating temperature range for the W9725G6KB-25 is -40°C to 85°C.
  • The power-up sequence for the W9725G6KB-25 is critical. Ensure that VCC is powered up before VPP, and VCC must be stable before applying clock signals.
  • The recommended clock frequency for the W9725G6KB-25 is up to 166 MHz, but it can operate at frequencies up to 200 MHz with reduced voltage.
  • The W9725G6KB-25 requires a reset circuit that can hold the device in reset for at least 10ms after power-up. A simple RC circuit can be used for this purpose.
  • The maximum current consumption of the W9725G6KB-25 is 350mA, but this can vary depending on the operating frequency and voltage.
