ADUC831BS Description
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—8 kbytes mask programmable ROM
80C552—ROMless version of the 83C552
87C552—8 kbytes EPROM (described in a separate chapter.
