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
= 10ns, V
IL
= 0.5V;
XTAL2 disconnected; RST = Port 0 = V
CC
, MSEL = V
SS
.
Note 3: Idle mode, I
IDLE
, is measured with all output pins disconnected; XTAL1 driven with t
CLKR
, t
CLKF
= 10ns, V
IL
= 0.5V; XTAL2
disconnected; Port 0 = V

Note 4: Stop mode, I
STOP
, is measured with all output pins disconnected; Port 0 = V
CC
; XTAL2 not connected; RST = MSEL =
XTAL1 = V
SS
.
Note 5: Pin capacitance is measured with a test frequency: 1MHz, T
A
= +25°C. This specification is characterized but not produc-
tion tested.
Note 6: V
CCO2
is measured with V
CC
< V
LI
and a maximum load of 10µA on V
CCO
.
Note 7: I
CCO1
is the maximum average operating current that can be drawn from V
CCO
in normal operation.
Note 8: I
LI
is the current drawn from the V
LI
input when V
CC
= 0V and V
CCO
is disconnected. Battery-backed mode is 2.5V ≤ V
BAT
≤ 4.0; V
CC
≤ V
BAT
; V
SDI
should be ≤ V
ILS
for I
BAT
max.
Note 9: PF pin operation is specified with V
BAT
≥ 3.0V.
Note 10: V
IHS
minimum is 2.0V or V
CCO
, whichever is lower.
Note 11: 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 12: 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.
