RTAX

of spaceflight systems. The RTAX-S/SL family is a derivative of the Axcelerator

million system gates. The RTAX-S/SL FPGA provides the designer with nearly 250K ASIC gates, with

error detection and correction (EDAC) protected static RAM. Microsemi offers the RTAX-S/SL device in

two package styles: the ceramic column grid array (CCGA) and ceramic quad flat pack (CQFP).

Microsemi has developed four low cost prototyping methods for RTAX-S/SL devices packaged in a

CQFP or CCGA, using the Axcelerator family fine pitch ball grid array (FBGA) or ceramic land grid array

(LGA) as a prototyping vehicle:

This document describes the adapter sockets for the CQFP and the procedure for assembling them.

Note:

The CQFP to FBGA adapter sockets have an FBGA configuration on the top and a CQFP configuration

on the bottom. The adapter sockets enable customers to use a commercial Axcelerator FG package

during prototyping, and then switch to an equivalent CQ256 or CQ352 package for production. There are

four CQFP to FBGA adapter sockets available. Their ordering part numbers are listed in

These adapters are intended for developing functional prototypes and are not designed for

at-speed testing, especially for sensitive I/Os such as LVDS. The intention of the prototyping

adapters is to provide functional validation; they may limit the performance of the FPGA.

-S/SL devices are radiation-tolerant FPGAs that offer industry- leading advantages for designers
