NOTES:
1. All voltage referenced to ground.
2. SDI should be taken to a logic high when V
CC
=+5V, and to approximately 3V when V
CC
<3V.
3. 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
.
4. Maximum operating I
CC
is measured with all output pins disconnected; XTAL1 driven with t

6. Stop mode I

7. Pin capacitance is measured with a test frequency – 1 MHz, t
A
= 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.
