PCA9560 Description
The PCA9560 is a 20-pin CMOS device consisting of two 6-bit non-volatile EEPROM registers, 5 hardware pin inputs and a 5-bit multiplexed output with one latched EEPROM bit. It is used for DIP switch-free or jumper-less system configuration and supports Mobile and Desktop VID Configuration, where 3 preset values (2 sets of internal non-volatile registers and 1 set of external hardware pins) set processor voltage for...
