Mechanical Information and Circuit Design Guidelines
Mechanical Information
BELASIGNA 250 is available in two packages in
production quantities:
A 7 x 7 mm LFBGA package where all the device I/Os
are available at the BGA level
A 5 x 5 mm CABGA package
BELASIGNA 250 also exists in a PLCC package, but it
is only used on the evaluation and development board. The
PLCC package is not available in production quantities. A
separate data sheet is available for this part (part number
0W548001XTD). Contact ON Semiconductor for more
information on this package option.
All BELASIGNA 250 package options are Green
(RoHS compliant). Contact ON Semiconductor for
supporting documentation.
A total of 51 active pins are present on the BELASIGNA 250 7 x 7 mm LFBGA package option. This package contains a
total of 64 balls, organized in an 8by8 array. A description of these pins is given in Table 3.
