Pinout, Package, and Ordering Information
The L64724 is available in a 100-pin PQFP and an 80-pin TQFP
package. Table 8 lists ordering information for the L64724.
The tables and gures that follow provide a pinout and a mechanical
drawing for each package.
Pinouts
Figure 11 gives the pinout for the 100-pin PQFP L64724 package, and
Figure 12 gives the 80-pin TQFP pinout. The 80-pin version offers a
serial, rather than a parallel, microcontroller interface and makes use of
the internal ADC module instead of external ADCs.
