NOTES:
1. All voltages are referenced to ground.
2. Maximum operating ICC is measured with all output pins disconnected; XTAL1 driven with tCLKR,
tCLKF=10ns, VIL = 0.5V; XTAL2 disconnected; RST = PORT0 = VCC.
3. Idle mode IIDLE is measured with all output pins disconnected; XTAL1 driven with tCLKR, tCLKF =
10ns, VIL = 0.5V; XTAL2 disconnected; PORT0 = VCC, RST = VSS.
4. Stop mode ISTOP is measured with all output pins disconnected; PORT0 = VCC; XTAL2 not
connected; RST = XTAL1 = VSS.
5. Pin capacitance is measured with a test frequency—1MHz, TA = +25°C.
6. 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.
7. PF pin operation is specified with VBAT ≥ 3.0V.
