About E0, E1, E2 pin internal connection of the M24C64WMN6TP.

Current data sheet says

"When not connected (left floating), these inputs are read as low (0).",

But old Datasheet (REV5.0) says

"Chip Enable (E0, E1, E2). These input signals are used to set the value that is to be looked for onthe three least significant bits (b3, b2, b1) of the 7bit Device Select Code.

These inputs must be tied to VCC or VSS, to establish the Device Select Code."

Which is correct, including the old device?

They have an internal pull-down?​

Best regards.​

Hello,

The latest datasheet must be taken in account. https://www.st.com/resource/en/datasheet/m24c64-f.pdf

(it's not mandatory to have Ei pins connected to Vss or Vcc as they are internally connected in pull down.)
