INTEGRATED CIRCUITS PCA9504A Glue chip 4 Product data Supersedes data of 2003 Nov 10 2004 May 11 Philips Semiconductors Philips Semiconductors Product data Glue chip 4 PCA9504A 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.
