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.
