This Hardware Description describes the 8xC251TA, 8xC251TB, 8xC251TP, 8xC251TQ (referred to collectively as the 8xC251Tx) embedded microcontroller, which is the newest member of the MCS®251 microcontroller family. The 8xC251Tx is pin and code compatible with the 8xC251Sx but is enhanced with the addition of new features.
This document addresses the differences between the two members of the MCS251 microcontroller family. For a detailed description of the MCS251 microcontroller core and standard peripherals shared by both the 8xC251Sx and 8xC251Tx, please refer to the 8xC251SA, 8xC251SB, 8xC251SP, 8xC251SQ Embedded Microcontroller User’s Manual (272795).
