Description

DESCRIPTION
  The PCA9561 is a 20-pin CMOS device consisting of four 6-bit non-volatile EEPROM registers, 6 hardware pin inputs and a 6-bit multiplexed output. PCA9561 is used for DIP switch-free or jumper-less system configuration and supports Mobile and Desktop VID Configuration, where 5 preset values (4 sets of internal non-volatile registers and 1 set of external hardware pins) set processor voltage of PCA9561 for operation in various performance or battery conservation sleep modes.
 
    The PCA9561 is also useful in server and telecom/networking applications when used to replace DIP switches or jumpers, since the settings can be easily changed via I2C/SMBus without having to power down the equipment to open the cabinet. The non-volatile memory of PCA9561 retains the most current setting selected before the power is turned off.
