How is the Vi/o level actually derived from "Vi/o < Vcc + 200mV? - KBA203369

Version: **

Translation - Japanese: “Vi/o &lt; Vcc + 200mV” から実際にVi/oレベルを導き出す方法 - KBA203369 - Community Translated (JA)

Question:

How is the Vi/o level actually derived from "Vi/o < Vcc + 200mV?"

Answer:

The actual level of Vi/o should be 200mV less than that of Vcc.

As an example, if the level of Vcc is at 3.4V, then the level of Vi/o should be set no higher than 3.2V; if the level of Vcc is 3.0V, then the level of Vi/o should be set no higher than 2.8V, and so forth.

It's important to note that if you do not set Vi/o to "Vi/o < Vcc +200mV,” it will not destroy or damage the Cypress Flash memory although you may expect erratic operation of the device so we highly recommend following this process.
