Description

The SM8051/8052 series product is an 8 - bit single chip

micro controller with 4/8 KB ROM embedded. It

provides hardware features and a powerful instruction set,

necessary to make it a versatile and cost effective

controller for those applications demand up to 32 I/O pins

or need up to 4/8 KB ROM memory either for

program or for data or mixed.
