1.11.1. 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). The following figure 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.
- Used 0.5-mm increase for front and back of nominal foot length.
- Used 0.3-mm increase to maximum foot width.
