NOTES:
1. Parameters are valid over operating temperature range unless otherwise specified.
2. Load capacitance for port 0, ALE, and PSEN = 100pF, load capacitance for all other outputs = 80pF.
3. Interfacing the 8XC51 and 80C31 to devices with float times up to 45ns is permitted. This limited bus contention will not cause damage to
Port 0 drivers.
4. Variable clock is specified for oscillator frequencies greater than 16MHz to 33MHz. For frequencies equal or less than 16MHz, see 16MHz
“AC Electrical Characteristics”, page 23.
5. Parts are guaranteed to operate down to 0Hz.
