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 87C51, 80C51, 87C52 or 80C52 to devices with float times up to 45ns is permitted. This limited bus contention will not cause
4. Variable clock is specified for oscillator frequencies greater than 16 MHz to 33 MHz. For frequencies equal or less than 16 MHz, see 16 MHz
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
