Notes:

The 95nm, x16 and x32 products use SAC305 package solder ball composition, as shown
in Figure 2.
Both the x16 (60-ball) and the x32 (90-ball) packages for the 78nm product use SAC105
solder ball composition. This aligns with the industry trend toward SAC105 composition
for enhanced drop test performance. The surface mount conditions for SAC105 are the
same as for SAC305.
In addition, the 78nm, x16 product offers a smaller, 8mm x 9mm package outline to
conserve application board space, as shown in Figure 3 on page 4. The ball assignments
for both 78nm packages are JEDEC compliant.
