CHAPTER 2
ARCHITECTURAL OVERVIEW
The 16-bit 8XC196MC, 8XC196MD, and 8XC196MH CHMOS microcontrollers are designed
to handle high-speed calculations and fast input/output (I/O) operations. They share a common
architecture and instruction set with other members of the MCS
®
96 microcontroller family.
NOTE
This manual describes a family of microcontrollers. For brevity, the name
8XC196Mx is used when the discussion applies to all family members. When
information applies to specific microcontrollers, individual product names are
used.
2.1 TYPICAL APPLICATIONS
MCS 96 microcontrollers are typically used for high-speed event control systems. Commercial
applications include modems, motor-control systems, printers, photocopiers, air conditioner con-
trol systems, disk drives, and medical instruments. Automotive customers use MCS 96 microcon-
trollers in engine-control systems, airbags, suspension systems, and antilock braking systems
(ABS).
2.2 MICROCONTROLLER FEATURES
Table 2-1 lists the features of each member of the 8XC196Mx family.
