CHAPTER 2
ARCHITECTURAL OVERVIEW
This chapter describes architectural differences between the 8XC196Lx (87C196LA, 87C196LB,
and 83C196LD) and the 8XC196Kx (8XC196Kx, 8XC196Jx, and 87C196CA) microcontroller
families. Both the 8XC196Lx and the 8XC196Kx are designed for high-speed calculations and
fast I/O, and share a common architecture and instruction set with few deviations. This chapter
provides a high-level overview of the deviations between the two families.
NOTE
This supplement describes two product families within the MCS
®
96
microcontroller family. For brevity, the name 8XC196Lx is used when the
discussion applies to all three Lx controllers. Likewise, the name 8XC196Kx is
used when the discussion applies to all the Kx, Jx, and CA controllers.
2.1 MICROCONTROLLER FEATURES
Table 2-1 lists the features of the 8XC196Lx and the 8XC196Kx.

NOTES:
1.
Optional. The second character of the device name indicates the presence and type of nonvolatile
memory. 80C196
xx = none; 83C196xx = ROM; 87C196xx = OTPROM or EPROM.
2. Register RAM amounts include the 24 bytes allocated to core SFRs and the stack pointer.
