PIN DESCRIPTIONS
The MC68HC11PH8 is available in an 84-pin plastic-leaded chip carrier (PLCC) and in an 112-pin thin
quad flat pack (TQFP); in addition to those two packages, the MC68HC711PH8 is also available in an
84-pin windowed cerquad package, to allow the EPROM to be erased. Most pins on this MCU serve
two or more functions, as described in the following paragraphs. Refer to Figure 2-1 and to Figure 2-2
which show the pin assignments for the 84 and 112-pin packages respectively.
