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 80C32/52 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.
