11Package Parameters

VNC2 is available in six RoHS Compliant packages, three QFN packages (64QFN, 48QFN & 32QFN) and

three LQFP packages (64LQFP, 48LQFP & 32LQFP). All packages are lead (Pb) free and use a ‘green’

compound. The packages are fully compliant with European Union directive 2002/95/EC.

The mechanical drawings of all six packages are shown in sections 11.2 to 11.7– all dimensions are in

millimetres.

The solder reflow profile for all packages can be viewed in Section 11.8.

11.1 VNC2 Package Markings

An example of the markings on each package is shown in Figure 11.1. The FTDI part number is too long

for the 32 QFN package so in this case the last two digits are wrapped down onto the date code line as

shown in Figure 11.2.
