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 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 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 I2C-bus or SMBus.

FUNCTIONAL DESCRIPTION
When the MUX_SELECT signal is logic 0, the multiplexer will select the data from the non-volatile register to drive on the MUX_OUT pins. When the MUX_SELECT signal is logic 1, the multiplexer will select the MUX_IN lines to drive on the MUX_OUT pins. The MUX_SELECT signal is also used to latch the NON_MUXED_OUT signal which outputs data from the non-volatile register. The NON_MUXED_OUT signal latch is transparent when MUX_SELECT is in a logic 0 state, and will latch data when MUX_SELECT is in a logic 1 state. When the active-LOW OVERRIDE_N signal is set to logic 0 and the MUX_SELECT signal is at a logic 0, all outputs will be driven to logic 0. This information is summarized in Table 1. The Write Protect (WP) input is used to control the ability to write the contents of the 6-bit non-volatile register. If the WP signal is logic 0, the I2C-bus will be able to write the contents of the non-volatile register. If the WP signal is logic 1, data will not be allowed to be written into the non-volatile register. The factory default for the contents of the non-volatile register are all logic 0. These stored values can be read or written using the I2C-bus (described in the next section). The OVERRIDE_N, WP, MUX_IN, and MUX_SELECT signals have internal pull-up resistors. See the DC and AC Characteristics for hysteresis and signal spike suppression figures.
I2C INTERFACE
Communicating with this device is initiated by sending a valid address on the I2C-bus. The address format (see FIgure 1) has 5 fixed bits and two user-programmable bits followed by a 1-bit read/write value which determines the direction of the data transfer.

HARDWARE SELECTABLE
Figure 2. I2C Address Byte Following the address and acknowledge bit are 8 data bits which, depending on the read/write bit in the address, will read data from or write data to the non-volatile register. Data will be written to the register if the read/write bit is logic 0 and the WP input is logic 0. Data will be read from the register if the bit is logic 1. The four high-order bits are latched outputs, while the four low order bits are multiplexed outputs (Figure 3). NOTE: 1. To ensure data integrity, the non-volatile register must be internally write protected when VCC to the I2C-bus is powered down or VCC to the component is dropped below normal operating levels.

NOTE: 1. NON_MUXED_OUT state will be the value present on the output at the time of the MUX_SELECT input transitioned from a logic 0 to a logic 1 state.
POWER-ON RESET (POR)
When power is applied to VCC, an internal power-on reset holds the PCA9559 in a reset state until VCC has reached VPOR. At that point, the reset condition is released and the PCA9559 volatile registers and I2C/SMBus state machine will initialize to their default states. The MUX_OUT and NON_MUXED_OUT pin values depend on: - the OVERRIDE # and MUX_SELECT logic levels - the previously stored values in the EEPROM register/current MUX_IN pin values as shown in the Function Table.
