FEATURES
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 operation in either performance, deep
sleep or deeper sleep modes. The PCA9560 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
cabinet. The non-volatile memory retains the most current setting
selected before the power is turned off.
The PCA9560 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 PCA9560 over the
older PCA9559 device in this application is that it contains two
internal non-volatile EEPROM registers instead of just one, allowing
three independent settings (performance operation, deep sleep
mode and deeper sleep mode) instead of only two (performance
operation and deep sleep mode). The PCA9560 is footprint
compatible and a drop-in replacement for the PCA9559, without any
software modifications required.
The PCA9560 has 2 address pins allow up to 4 devices to be placed
on the same I
