13.1 R10000 Single-Chip Package, 599CLGA


The standard single-chip R10000 package is a 599CLGA (ceramic land grid array), as shown in Figure 13-1.

The 599CLGA package minimizes output switching noise by reducing the inductance of the power and ground paths leading into the package. Much of the decrease in power/ground inductance is accomplished by shortening the wire bonds running from the die pads to the package inner leads. The 599CLGA is designed with its cavity-side down, and the die is connected directly to a thermal slug.
