NXP PCA9561PW112

Overview

The PCA9561PW,112 is a 20-pin CMOS device consisting of four 6-bit non-volatile EEPROMregisters, six hardware pin inputs and a 6-bit multiplexed output. It is used for DIPswitch-free or jumper-less system configuration and supports Mobile and Desktop VIDConfiguration, where five preset values (four sets of internal non-volatile registers andone set of external hardware pins) set processor voltage for operation in variousperformance or battery conservation sleep modes. The PCA9561PW,112 is also useful in serverand telecommunications/networking applications when used to replace DIP switches orjumpers, since the settings can be easily changed via I²C-bus/SMBus without having topower down the equipment to open the cabinet. The non-volatile memory retains the mostcurrent setting selected before the power is turned off.

The PCA9561PW,112 has two address pins, allowing up to four devices to be placed on the sameI²C-bus or SMBus.
