Package Layout Recommendation
Sharp flash-based EPC16 and EPC8 devices in the 100-pin PQFP packages have
different package dimensions than other Altera 100-pin PQFP devices (including the
Micron flash-based EPC4 and Intel flash-based EPC16, EPC8, and EPC4). Figure 9
shows the 100-pin PQFP PCB footprint specifications for EPC devices that allows
vertical migration between all devices. These footprint dimensions are based on
vendor-supplied package outline diagrams.
