1. AN 114: Board Design Guidelines for Intel® Programmable Device Packages
As programmable logic devices (PLDs) increase in density and I/O pins, the demand for small packages and diverse packaging options continues to grow. Ball-grid array (BGA) packages are an ideal solution because the I/O connections are on the interior of the device, improving the ratio between pin count and board area. Typical BGA packages contain between two to eight more connections as quad flat pack (QFP) packages. Furthermore, BGA solder balls are considerably stronger than QFP leads, resulting in robust packages that can tolerate rough handling.
This application note provides the recommended PCB design guidelines for some of the more complex package options offered for Intel® Programmable Devices except for Intel® Stratix® 10 devices and beyond.
For Enpirion power solution products, PCB guidelines and GERBER files are available for each device, with the information available within each Enpirion datasheet.
