DATA RETENTION MODE
With valid V
CC
applied, the M48Z2M1/2M1Y oper-
ates as a conventional BYTEWIDE
static RAM.
Should the supply voltage decay, the RAM will
automatically power-fail deselect, write protecting
itself t
WP
after V
CC
falls below V
PFD
. All outputs
become high impedance, and all inputs are treated
as "don’t care."
If power fail detection occurs during a valid access,
the memory cycle continues to completion. If the
memory cycle fails to terminate within the time t
WP
,
write protection takes place. When V
CC
drops be-
low V
SO
, the control circuit switches power to the
internal energy source which preserves data.
The internal coin cells will maintain data in the
M48Z2M1/2M1Y after the initial application of V
CC
for an accumulated period of at least 10 years when
V
CC
is less than V
SO
. As system power returns and
V
CC
rises above V
SO
, the batteries are discon-
nected, and the power supply is switched to exter-
nal Vcc. Write protection continues for t
ER
after V
CC
reaches V
PFD
to allow for processor stabilization.
After t
ER
, normal RAM operation can resume.
