UM62256E-70LL Frequently Asked Questions (FAQ)

  • The maximum operating temperature range for the UM62256E-70LL is -40°C to 85°C.

  • The power-up sequence should be VCC first, then VPP, and the power-down sequence should be VPP first, then VCC. This ensures that the device is properly initialized and avoids any potential latch-up conditions.

  • A decoupling capacitor of 0.1uF to 1uF is recommended to be placed as close to the VCC pin as possible to filter out noise and ensure stable operation.

  • To ensure data retention, the VCC pin should be lowered to 2V or less before powering down, and the CE pin should be held high during power-down to prevent any unwanted writes.

  • The maximum clock frequency supported by the UM62256E-70LL is 70MHz.
