PCA9504A
Datasheet
General description
The PCA9504A Glue Chip 4 is a highly integrated and cost-efficient custom ASIC that reduces logic part count, overall component cost, and board space requirements for PC designers and manufacturers. The Glue Chip 4 supports the latest generation of high-volume platforms based on Intel[ processors and chipsets that require 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).
