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. It 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
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 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 PCA9561 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 main advantage of the PCA9561 over
older devices, such as the PCA9559 or PCA9560, is that it contains
four internal non-volatile EEPROM registers instead of just one or
two, allowing five independent settings which allows a more
accurate CPU voltage tuning depending on specific applications.
The PCA9561 has 2 address pins, allowing up to 4 devices to be
placed on the same I
