**All parameters apply to both commercial and industrial temperature operation unless otherwise noted.
Note 1: All voltages are referenced to ground.
Note 2: Maximum operating I
CC
is measured with all output pins disconnected; XTAL1 driven with t
CLKR
, t
CLKF
= 10 ns, V
IL
= 0.5V; XTAL2
disconnected; RST = PORT0 = V

Note 3: Idle mode I
IDLE
is measured with all output pins disconnected; XTAL1 driven with t

CLKF
= 10ns, V
IL

Note4: Stop mode I
STOP
is measured with all output pins disconnected; PORT0 = V

.
Note 5: Pin capacitance is measured with a test frequency: 1MHz, T
A
= +25°C.
Note 6: I
CCO1
is the maximum average operating current that can be drawn from V
CCO
in normal operation.
Note 7:
I
LI
is the current drawn from V
LI
input when V
CC
= 0V and V
CCO
is disconnected. Battery-backed mode is 2.5V ≤ V
BAT
≤ 4.0; V
CC

BAT
; V
SDI
should be ≤ V
ILS
for I

max.
Note 8: V
CCO2
is measured with V
CC
< V
LI
, and a maximum load of 10µA on V
CCO
.
Note 9: Crystal startup time is the time required to get the mass of the crystal into vibrational motion from the time that power is first
applied to the circuit until the first clock pulse is produced by the on-chip oscillator. The user should check with the crystal
vendor for a worst-case specification on this time.
Note 10: SDI is deglitched to prevent accidental destruction. The pulse must be longer than t
SPR
to pass the deglitcher, but SDI is not
guaranteed unless it is longer than t
SPA
.
Note 11: V
IHS
minimum is 2.0V or V
CCO
, whichever is lower.
Note 12: This parameter applies to industrial temperature operation.
Note 13:
PF pin operation is specified with V
BAT
≥ 3.0V.
