When used in accordance with the CompactPCI Packet Switching Backplane Specification,
PICMG 2.16, Version 1.0, the ZT 5504 functions as a "Dual Link Port Node" board. The
ZT 5504 can be connected to a system's fabric-switched Link Ports A and B, and can be
inserted into system or peripheral slots. The ZT 5504 is keyed for insertion into compatible
slots.

Manufacturers Group.
Processor
The ZT 5504 uses the Mobile Pentium III Processor - M in a BGA2 package. The 0.18 micron
BGA2 package is a highly integrated assembly containing a mobile version of the Pentium III
processor and its immediate system-level support. This mobile processor runs at a lower
voltage than the desktop version.
The 256 KB on-die transfer L2 cache is integrated with the CPU, eliminating the need for
separate components and improving performance. The BGA2 package Pentium III processor
also operates with a 100 MHz Processor Side Bus for faster access to memory and data.

Chipset
The Intel 440GX AGPset consists of the 82443GX Host Bridge and the 82371EB (PIIX4E) I/O
subsystem chip. The Host Bridge includes an optimized SDRAM controller. The I/O subsystem
is a highly integrated PCI ISA IDE Xcelerator Bridge.

AGPset" topic in Appendix E contains a link to information about the chipset.
PCI-to-PCI Bridge (P2P)
The ZT 5504 features one Intel® 21154 PCI-to-PCI bridge to support the
buses. The bridge provides the isolation, arbitration, and clocks for seven PCI peripheral cards
without the need for an external bridge board.
Special features of the 21154 include:
• 33 MHz or 66 MHz PCI bus operation
• Support for independent primary and secondary PCI clocks
• 64-bit PCI operation
