1.5 Functional Pin Description
NOTE
A line over a signal name indicates an active low signal. For example,
RESET is active high and RESET is active low. Any reference to voltage,
current, resistance, capacitance, time, or frequency specified in the
following paragraphs will refer to the nominal values. The exact values and
their tolerance or limits are specified in Chapter 15 Electrical Specifications.
The MC68HC05L25 is available in the 48-pin VQFP and 52-pin TQFP. The pin assignments for the 48-pin
VQFP are shown in Figure 1-2 and Table 1-2.
