• Manufacturer Part Number: P80C32X2FN
• Description: MCU 8-Bit 80C 80C51 CISC ROMLess 5V 40-Pin PDIP Tube
• Manufacturer: NXP Semiconductors

Specifications of P80C32X2FN

• Package: 40PDIP
• Device Core: 80C51
• Family Name: 80C
• Maximum Speed: 33 MHz
• Operating Supply Voltage: 5 V
• Data Bus Width: 8 Bit
• Number Of Programmable I/os: 32
• Interface Type: UART
• Number Of Timers: 3
• Ram Size: 256 Byte
• Program Memory Type: ROMLess
• Operating Temperature: -40 to 85 °C

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 outputs = 80 pF
3. Interfacing the microcontroller to devices with float time up to 45 ns is permitted. This limited bus contention will not cause damage to port 0
4. Parts are guaranteed by design to operate down to 0 Hz.
