PCA9561PW - Brand New PHI Interface - Specialized
-
Description
The PCA9561PW is a 20-pin CMOS device used for DIP switch-free or jumper-less system configuration. It consists of four 6-bit non-volatile EEPROM registers, 6 hardware pin inputs, and a 6-bit multiplexed output. It supports Mobile and Desktop VID Configuration, allowing for easy processor voltage settings in various performance or battery conservation sleep modes. The PCA9561PW is commonly used in server and telecom/networking applications to replace DIP switches or jumpers, as the settings can be changed via I2C/SMBus without powering down the equipment or opening the cabinet. The non-volatile memory retains the most current setting even when the power is turned off.
