Package summary
The package selection must consider the constraints that are strongly dependent upon the application.
The list below summarizes the most frequent ones:
- Number of interfaces required: Some interfaces may not be available on some packages. Some interfaces combinations may not be possible on some packages.
- PCB technology constrains: Small pitch and high-ball density may require more PCB layers and higher‑class PCB.
- Package height
- PCB available area
- Noise emission or signal integrity of high-speed interfaces
- Smaller packages usually provide better signal integrity. This is further enhanced as small-pitch and high-ball density requires multilayer PCBs that allow better supply/ground distribution.
- Compatibility with other devices
