PCI2050B General Description
The PCI2050B device is available in four packages, a 257-terminal GHK MicroStar BGATM package, a 257-terminal RoHS-compliant ZHK MicroStar BGATM package, a 208-terminal PDV package, or a 208-terminal PPM package. The GHK and ZHK packages are mechanically and electrically identical, but the ZHK is a RoHS-compliant design.
Throughout the remainder of this manual, only the GHK package designator is used for either the GHK or the ZHK package. Figure 2−1 is the GHK-package terminal diagram. Figure 2−2 is the PDV-package terminal diagram.
Figure 2−3 is the PPM-package terminal diagram. Table 2−1 lists terminals on the PDV packaged device in increasing numerical order with the signal name for each. Table 2−2 lists terminals on the PPM packaged device in increasing alphanumerical order with the signal name for each. Table 2−3 lists terminals on the GHK packaged device in increasing alphanumerical order with the signal name for each. Table 2−4, Table 2−5, and Table 2−6 list the signal names in alphabetical order, with corresponding terminal numbers for each package type.
