DESCRIPTION
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 I

C/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 to
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 7.5%. Lower CPU voltage reduces
power consumption.
The PCA9559 has 2 address pins allowing up to 4 devices to be
placed on the same I

C-bus or SMBus.
