Cmos Single-chip 8-bit Microcontroller - Nxp Semiconductors

The 8XC528 single-chip 8-bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 Microcontroller family. The 8XC528 has the same instruction set as the 80C51. Three versions of the derivative exist: 83C528 32k bytes mask programmable ROM 80C528 ROMless version of the 83C528 87C528 32k bytes EPROM (described in a separate data sheet) This device provides architectural enhancements that make it applicable in a variety of applications in consumer, telecom and general control systems, especially in those systems which need large ROM and RAM capacity on-chip.
