P80C552 - NXP

P80C552 Single-chip 8-bit microcontroller

The 80C552/83C552 (hereafter generically referred to as 8XC552) Single-Chip 8-Bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The 8XC552 has the same instruction set as the 80C51. Three versions of the derivative exist: • 83C552—8k bytes mask programmable ROM • Three operating ambient.

Features

• 80C51 central processing unit
• 8k × 8 ROM expandable externally to 64k bytes
•
•
•
• I2C-bus serial I/O port with byte oriented master and slave functions Full-duplex UART compatible with the standard 80C51 On-chip watchdog timer Three speed ranges:
  – 3.5 to 16MHz
  – 3.5 to 24MHz (ROM, ROMless only)
  – 3.5 to 30MHz (ROM, ROMless only)
