An internal Power-on Data Protection mechanism
in the M93Cx6 inhibits the device when the supply
is too low.

Note: 1. See PACKAGE MECHANICAL section for package di-
mensions, and how to identify pin-1.
2. DU = Don’t Use.
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 VCC or VSS. Direct connection of DU to
VSS is recommended for the lowest stand-by pow-
er consumption.
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 VCC)
the x16 organization is selected; when Organiza-
tion Select (ORG) is connected to Ground (VSS)
the x8 organization is selected. When the M93Cx6
is in stand-by mode, Organization Select (ORG)
should be set either to VSS or VCC for minimum
power consumption. Any voltage between VSS
and VCC applied to Organization Select (ORG)
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 not be selected (that is, Chip Select Input
(S) must be driven Low) until the supply
voltage reaches the operating value VCC
–
When VCC reaches its valid level, the device is
properly reset (in the Write Disable mode) and
is ready to decode and execute incoming
instructions.
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.
