Figure 10.2 QFN-32 Package Dimensions
The FT245RQ is supplied in a RoHS compliant leadless QFN-32 package. The package is lead ( Pb ) free,
and uses a „green‟ compound. The package is fully compliant with European Union directive 2002/95/EC.
This package is nominally 5.00mm x 5.00mm. The solder pads are on a 0.50mm pitch. The above
mechanical drawing shows the QFN-32 package. All dimensions are in millimetres.
The centre pad on the base of the FT245RQ is not internally connected, and can be left unconnected, or
connected to ground (recommended).
The date code format is YYXX where XX = 2 digit week number, YY = 2 digit year number.
The code XXXXXXX is the manufacturing LOT code. This only applies to devices manufactured after April
2009.
