NOTES:
1. Parameters are valid over operating temperature range unless otherwise specified.
2. Load capacitance for port 0, ALE, and PSEN = 100 pF, load capacitance for all other outputs = 80 pF.
3. Interfacing the 80C31 and 80C32 to devices with float times up to 45ns is permitted. This limited bus contention will not cause damage to
Port 0 drivers.
4. See application note AN457 for external memory interface.
5. Parts are guaranteed to operate down to 0 Hz. When an external clock source is used, the RST pin should be held high for a minimum of
20
s for power-on or wakeup from power down.
