platforms based on Intel
additional external circuitry in order to function properly. It is used on
entry servers/workstations (840 and 860 chipsets), high-end
desktops (820 and 850 chipsets), as well as mid range (815, 830
and 845 chipsets) and low-end (810 chipset) motherboards. Some
of these functionalities include meeting timing specifications,
buffering signals, and switching between power wells.
The PCA9504A Glue Chip 4 integrates miscellaneous motherboard
logic and analog functions into a single, small footprint 56-pin
TSSOP device. The Glue Chip 4 typically resides on the
motherboard close to the I/O controller Hub (ICH) and is optimized
for the Intel 82801BA I/O controller hub (ICH2).
