PCA9559PW 5-Bit Multiplexed/1-Bit Latched 6-Bit I²C EEPROM DIP Switch

PublishTime：2022-07-19

●The PCA9559 is a 20-pin CMOS device consisting of one 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 2 preset values (1 set of internal non-volatile registers and 1 set of external hardware pins) set processor voltage for operation in either performance or deep sleep modes.The PCA9559 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 retains the most current setting selected before the power is turned off.
●The PCA9559 typically resides between the CPU and Voltage Regulator Module (VRM) when used for CPU VID (Voltage IDentification code) configuration. It is used to bypass the CPU-defined VID values and provide a different set of VID values the VRM, if an increase in the CPU voltage is desired. An increase in CPU voltage combined with an increase in CPU frequency leads to a performance boost of up to 7.5pct. Lower CPU voltage reduces power consumption.
●The PCA9559 has 2 address pins allowing up to 4 devices to be placed on the same I²C-bus or SMBus.
