P83CE559 Overview
The P80CE559/P83CE559 (hereafter generically referred to as P8xCE559) single-chip 8-bit microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The P8xCE559 has the same instruction set as the 80C51. Three versions of the derivative exist:.
