NOTES:
1. All voltage referenced to ground.
2. SDI should be taken to a logic high when VCC=+5V, and to approximately 3V when VCC<3V.
3. SDI is deglitched to prevent accidental destruction. The pulse must be longer than tSPR to pass the deglitcher,
but SDI is not guaranteed unless it is longer than tSPA.
4. Maximum operating ICC is measured with all output pins disconnected; XTAL1 driven with tCLKR, tCLKF=10 ns,
VIL = 0.5V; XTAL2 disconnected; RST = PORT0 = VCC.
5. Idle mode IIDLE is measured with all output pins disconnected; XTAL1 driven with tCLKR, tCLKF = 10 ns, VIL = 0.5V;
XTAL2 disconnected; PORT0 = VCC, RST = VSS.
6. Stop mode ISTOP is measured with all output pins disconnected; PORT0 = VCC; XTAL2 not connected; RST =
XTAL1 = VSS.
7. Pin capacitance is measured with a test frequency – 1 MHz, tA = 25°C.
8. Crystal start–up 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.
