This document contains information on products with “[M] [C] '94 '95 C” as the last line of the top marking

diagram.

A member of the Intel family of 8-bit MCS 251 microcontrollers, the 8XC251SA/SB/SP/SQ is binary-

code compatible with MCS 51 microcontrollers and pin compatible with 40-lead PDIP and 44-lead PLCC

MCS 51 microcontrollers. MCS 251 microcontrollers feature an enriched instruction set, linear addressing,

and efficient C-language support. The 8XC251SA/SB/SP/SQ has 512 bytes or 1 Kbyte of on-chip RAM and is

available with 8 Kbytes or 16 Kbytes of on-chip ROM/OTPROM/EPROM, or without

ROM/OTPROM/EPROM. A variety of features can be selected by new user-programmable configurations.
