2.1 Pin Assignments
The 176-pin PZ low-profile quad flatpack (LQFP) pin assignments are shown in Figure 2-1. The 179-ball
GHH ball grid array (BGA) terminal assignments are shown in Figure 2-2 through Figure 2-5. The 176-ball
GJZ plastic ball grid array (PBGA) terminal assignments are shown in Figure 2-6 through Figure 2-
9.Table 2-2 describes the function(s) of each pin.
