Typical ratings are not guaranteed. The values listed are at room temperature, 3 V.
[2]
The IDD(oper), IDD(idle), and IDD(pd) specifications are measured using an external clock with the following functions disabled: comparators,
real-time clock, and watchdog timer.
[3]
The IDD(tpd) specification is measured using an external clock with the following functions disabled: comparators, real-time clock,
brownout detect, and watchdog timer.
[4]
See Section 8 “Limiting values” for steady state (non-transient) limits on IOL or IOH. If IOL/IOH exceeds the test condition, VOL/VOH may
exceed the related specification.
