Note 1: Results based on simulation data. Characterization data will be available at a later date. All voltages are referenced to
ground. Specifications to T
A
= -40°C are guaranteed by design and are not production tested.
Note 2: Typical values are not guaranteed. These values are measured at room temperature, V
DD
= 3.3V.
Note 3: This current is from V
BAT
only if (V
DD
< V
BAT
and V
DD
< V
RST
) or (STOP = 1, REGEN = 0, BOD = 1). Otherwise, this current
is from V
DD
.
Note 4: Measured on the V
DD
pin and the device not in reset. All inputs are connected to V
SS
or V
DD
. Outputs do not source/sink
any current. Timer enabled, RTC enabled, part executing JUMP $ from flash.
Note 5: If the RTC is on for parameters ISTOP_2, ISTOP_3, and ISTOP_4, a current equal to I
BAT1
is added to I
DD
.
Note 6: The maximum total current, I
OH(MAX)
and I
OL(MAX)
, for all outputs combined should not exceed 35mA to satisfy the maxi-
mum specified voltage drop.
Note 7: The timing listed above is clocked by 63 cycles of the internal 1MHz ±5% clock. There will be ROM code overhead, which is
a function of system clock. For data sheet purposes, a better way is to specify the limits that include ROM code execution
with specified system clock speed.
