PCA9561

Quad 6-bit multiplexed I²C-bus EEPROM DIP switch

Rev. 4 — 6 November 2012

Product data sheet

1. General description

The PCA9561 is a 20-pin CMOS device consisting of four 6-bit non-volatile EEPROM

registers, six 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 five preset values (four sets of internal non-volatile registers and

one 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 telecommunications/networking applications when used to replace DIP switches or

jumpers, since the settings can be easily changed via I²C-bus/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 two address pins, allowing up to four devices to be placed on the same

I²C-bus or SMBus.

2. Features and benefits

 Selection of non-volatile register_n as source to MUX_OUT pins via I²C-bus

 I²C-bus can override MUX_SELECT pin in selecting output source

 6-bit 5-to-1 multiplexer DIP switch

 Four internal non-volatile registers

 Internal non-volatile registers programmable and readable via I²C-bus

 Six open-drain multiplexed outputs

 400 kHz maximum clock frequency

 Operating supply voltage 3.0 V to 3.6 V

 5 V and 2.5 V tolerant inputs/outputs

 Useful for Speed Step configuration of laptop computer

 Two address pins, allowing up to four devices on the I²C-bus

 MUX_IN values readable via I²C-bus
