5. Last Buy and the Last Time Ship for MKY40
The scheduled first mass-production release for MKY40N which is in development
has been significantly changed. The reason for this slide is that the fabrication site has
exceeded its production capacity. In accordance with this, we change the schedule forthe first order start of MKY40N to be November 2021, and the Last Time Ship of MKY40
to be the end of March, 2023 considering to reduce the customer’s inconvenience.
We had planned to release MKY40N timely so that the customers can replace MKY40
without Last Buy as our intention.
However, this postponed release means that the customers need to take a Last Buy action
for MKY40 in order to satisfy the demanded quantity until the first mass-production releaseof MKY40N.
Please refer to the notification titled “Evaluation sample and mass production of MKY40N”
for detailed information about the evaluation sample and the mass-production.
In addition, recent situation of semiconductor supply chain will affect the lead time forpost-process and your delivery. We recommend you to place your order in earlier timeline
considering these back ground.
The EOL schedule of MKY40 is shown below for your reference.
