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
CC
)
the x16 organization is selected; when Organiza-
tion Select (ORG) is connected to Ground (V
SS
)
the x8 organization is selected. When the M93Cx6
is in stand-by mode, Organization Select (ORG)
should be set either to V
SS
or V
CC
for minimum
power consumption. Any voltage between V
SS
and V
CC
applied to Organization Select (ORG)
may increase the stand-by current.
INTERNAL DEVICE RESET
In order to prevent inadvertent Write operations
during Power-up, a Power On Reset (POR) circuit
is included.
At Power-up and Power-down, the device must
notbe selected (that is, the Chip Select Input (S)
must be driven Low) until the supply voltage
reaches the operating voltage V
CC
(as defined in
Tables
9
,
10
and
11
).
During Power-up (phase during which V
CC
is low-
er than V
CC
min but increases continuously), the
device will not respond to any instruction until V
CC
has reached the Power On Reset threshold volt-
age (this threshold is lower than the minimum V
CC
operating voltage defined in
DC AND AC PARAM-
ETERS
). Once V
CC
has passed the POR thresh-
old, the device is reset.
Prior to selecting the memory and issuing instruc-
tions to it, a valid and stable V
CC
voltage must be
applied. This voltage must remain stable and valid
until the end of the transmission of the instruction
and, for a Write instruction, until the completion of
the internal write cycle (t
W
).
During Power-down (phase during which V
CC
de-
creases continuously), as soon as V
CC
drops from
the normal operating voltage below the Power On
Reset threshold voltage, the device stops re-
sponding to any instruction sent to it.
ACTIVE POWER AND STANDBY POWER MODES
When Chip Select (S) is High, the device is select-
ed and in the Active Power mode. It consumes
I
CC
, as specified in Tables
15
,
16
,
17
,
18
and
19
.
When Chip Select (S) is Low, the device is dese-
lected.
If no Erase/Write cycle is in progress when Chip
Select goes Low, the device enters the Standby
Power mode, and the power consumption drops to
I
CC1
.
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.
