GENERAL DESCRIPTION

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:

? P83CE559 — 48 Kbytes mask programmable ROM

? P80CE559 — ROMless version of the P83CE559

? P89CE559 — not planned any longer
