Note 1: Specifications to 0°C are guaranteed by design and are not production tested.
Note 2: It is not recommended to write to flash memory when the supply voltage drops below the power-fail warning levels as
there is uncertainty in the duration of continuous power supply. The user application should check the status of the power-
fail warning flag before writing to flash to ensure complete write operations.
Note 3: The power-fail warning monitor and the power-fail reset monitor track each other with a minimum delta between the two of
0.11V.
Note 4: The power-fail reset and power-on-reset (POR) detectors operate in tandem to ensure that one or both signals are active
at all times when V
DD
< V
RST
. Doing so ensures the device maintains the reset state until the minimum operating voltage is
achieved.
Note 5: Guaranteed by design and not production tested.
Note 6: Measured on the V
DD
pin and the part not in reset. All inputs are connected to GND or V
DD
. Outputs do not source/sink
any current. Part is executing code from flash memory.
Note 7: The power-check interval (PCI) can be set to always on, 1024, 2048, or 4096 nanopower ring oscillator clock cycles.
Note 8: Current consumption during POR when powering up while V
DD

POR
.
Note 9: The minimum amount of time that V
DD
must be below V
PFW
before a power-fail event is detected.
Note 10: The maximum total current, I
OH
(max) and I
OL
(max), for all listed outputs combined should not exceed 32mA to satisfy
the maximum specified voltage drop. This does not include the IRTX output.
Note 11: Programming time does not include overhead associated with utility ROM interface.
