Ballout Diagrams for VF BGA Package
The L30 flash memory device is available in a VF BGA package with 0.75 mm ball-pitch. Figure 1
shows the ballout for the 64-Mbit and 128-Mbit devices in the 56-ball VF BGA package with a 7 x
8 active-ball matrix. Figure 2 shows the device ballout for the 256-Mbit device in the 63-ball VF
BGA package with a 7 x 9 active-ball matrix. Both package densities are ideal for space-
constrained board applications
