This chapter provides EP80579 package specifications.
48.1
Package Introduction
The EP80579 is offered in a 1,088 ball, Flip-Chip Ball Grid Array (FCBGA) package with
Lead-free only (RoHS 5/6 compliant) for commercial and industrial applications.

JTAG Boundary Scan Chain (BSC) and XOR Chain
The EP80579 implements a consistent, IEEE 1149.1 compliant JTAG Boundary Scan
Chain (BSC) for most interfaces (See Section 48.4, “Signal Pin Descriptions” for the
interfaces and signals) enabling a low-cost manufacturing test for boards. The
interfaces include the IICH interfaces. The BSC cell is defined in the Boundary Scan
Description Language (BSDL) documentation and the boundary scan is initiated by the
JTAG entry in the IMCH side.
Three high-speed interfaces, PCI Express*, SATA and USB, are not implemented in the
JTAG boundary scan. These interfaces are in an XOR Chain to validate connectivity of
high speed IO pins when JTAG control is unavailable (See Table 48-2, ”XOR Chain
Elements” and Section 48.4, “Signal Pin Descriptions” for the interfaces and signals).
XOR chain mode is initiated by the serial test mode entry of the IICH side. The XOR
chain provides the sequence of elements that include first element and XOR output
(last element) to allow the reader to know the chain starting and ending points. This
