P89C660 Philips Semiconductors, P89C660 Datasheet - Page 77

• Manufacturer Part Number: P89C660
• Description: 80C51 8-bit Flash microcontroller family
• Manufacturer: Philips Semiconductors

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 microcontroller to devices with float times up to 45ns is permitted. This limited bus contention will not cause damage to Port 0 drivers.
4. Parts are tested to 2 MHz, but are guaranteed to operate down to 0 Hz.
