69 balls, 8 x 11 mm body
FLB073
=
73 balls, 8 x 11.6 mm body
FLB093
=
93 balls, 8 x 11.6 mm body
FLJ073
=
73 balls, 8 x 11.6 mm body
FMA093
=
93 balls, 10 x 10 mm body
FNA093
=
93 balls, 10 x 10 mm body
FSC073
=
93 balls, 8 x 11.6 mm body
FSC093
=
93 balls, 8 x 11.6 mm body
FTA073

All packages are Fine-pitch Ball Grid Arrays (BGAs), 0.8 mm ball pitch. Differences
between package dimensions may also include body height and thickness, ball grid
size, and ball height and diameter. Consult the physical dimensions section in the
appropriate data sheet for more details.
