Package Options

The MC68HC811E2 is available in 52-pin PLCC (plastic leaded chip

carrier) and 48-pin DIP (dual in-line pack) packages. The MC68HC11F1

is available in 68-pin PLCC and 80-pin LQFP (low-profile quad flat pack)

packages.

Case 1

Example:

52-pin PLCC

Issue:

Only 68-pin PLCC or 80-pin LQFP available

Change required: Re-layout application to allow use of the 68-pin

PLCC or the 80-pin LQFP. See Figure 1 and

Figure 2.
