cle, a Busy/Ready signal is available on Serial
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.

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.

MEMORY ORGANIZATION
The M93Cx6 memory is organized either as bytes
(x8) or as words (x16). If Organization Select
(ORG) is left unconnected (or connected to V
the x16 organization is selected; when Organiza-
tion Select (ORG) is connected to Ground (V
the x8 organization is selected. When the M93Cx6
is in stand-by mode, Organization Select (ORG)
should be set either to V
power consumption. Any voltage between V
and V
may increase the stand-by current.
POWER-ON DATA PROTECTION
To prevent data corruption and inadvertent write
operations during power-up, a Power-On Reset
(POR) circuit resets all internal programming cir-
cuitry, and sets the device in the Write Disable
mode.
– At Power-up and Power-down, the device must

For the M93Cx6 devices (5V range) the POR
threshold voltage is around 3V. For the M93Cx6-
W (3V range) and M93Cx6-R (2V range) the POR
threshold voltage is around 1.5V.
