• Manufacturer Part Number: P80C31SFPN
• Description: 80C51 8-bit microcontroller family 4K/128 OTP/ROM/ROMless low voltage 2.7V.5.5V, low power, high speed 33 MHz
• Manufacturer: PHILIPS [NXP Semiconductors]

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
4. See application note AN457 for external memory interface.
5. Parts are guaranteed to operate down to 0Hz.
