Data Output (Q) when Chip Select Input (S) is driv-
en High.
An internal Power-on Data Protection mechanism
in the M93Cx6 inhibits the device when the supply
is too low.

Connections (Top View)
The DU (Don’t Use) pin does not contribute to the
normal operation of the device. It is reserved for
use by STMicroelectronics during test sequences.
The pin may be left unconnected or may be con-
nected to V_CC or V_SS. Direct connection of DU to
V_SS is recommended for the lowest stand-by pow-
er consumption.
