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 I2C bus or SMBus.

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 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 PCA9560 typically resides between the CPU and Voltage Regulator Module (VRM) when used for CPU VID (Voltage ORDERING INFORMATION PACKAGES 20-Pin Plastic SO TEMPERATURE RANGE –40 to +85 °C ORDER CODE PCA9560D TOPSIDE MARK PCA9560D DRAWING NUMBER SOT163-1 SOT360-1 20-Pin Plastic TSSOP –40 to +85 °C PCA9560PW PCA9560 Standard packing quantities and other packaging data are available at www.philipslogic.com/packaging. 2004 May 19 2 Philips Semiconductors Product data sheet Dual 5-bit multiplexed 1-bit latched I2C EEPROM DIP switch PCA9560 BLOCK DIAGRAM PCA9560 WRITE PROTECT NON-VOLATILE REGISTER 0 6-BIT EEPROM 6 6-BIT 2 to 1 DEMULTIPLEXER LATCH NON-MUXED_OUT NMO NON-VOLATILE REGISTER 1 6-BIT EEPROM 6 5 8 A0 A1 SCL SDA INPUT FILTER I2C/SMBus CONTROL LOGIC MUX_OUT_A VDD POWER-ON RESET 3 5-BIT 2 to 1 DEMULTIPLEXER GND MUX_OUT_C MUX_OUT_B MUX_IN_A MUX_OUT_D MUX_IN_B MUX_OUT_E MUX_IN_C 5 MUX_IN_D MUX_IN_E MUX_SELECT_1 SELECT LOGIC MUX_SELECT_0 SW00841 Figure 2.

The address of the PCA9560 is shown in Figure 3. To conserve power, no internal pull-up resistors are incorporated on the hardware selectable address pins and they must be pulled HIGH or LOW. The last bit of the slave address byte defines the operation to be performed. When set to logic 1 a read is selected while a logic 0 selects a write operation. CONTROL REGISTER Following the successful acknowledgement of the slave address, the bus master will send a byte to the PCA9560, which will be stored in the control register. This register can be written and read via the I2C-bus. D7 MSB 1 0 0 1 1 A1 A0 LSB R/W D6 D5 D4 D3 D2 D1 D0 SW00954 Figure 4. Control Register FIXED PROGRAMMABLE SW00955 Figure 3.

If more than one byte is sent sequentially, the second byte will be written in the other-volatile register, on the following STOP condition. If any more data bytes are sent after the second byte, they will not be acknowledged and no bytes will be written to the non-volatile registers. After a byte is read from or written to the EEPROM, the part automatically points to the next non-volatile register. If the command code was FFH, the MUX_IN values are sent with the three MSBs padded with zeroes as shown below. If the command codes was 00H, then the non-volatile register 1 is sent, and if the command code was 01H, then the non-volatile register 1 is sent.

If the read/write bit in the address is a logic 1, then a read operation follows and the data sent out depends on the previously stored command code. The MUX_SELECT_1 pin can function as the over-ride pin as on the PCA9559 if the non-volatile register 1 is left at all 0s. The NON_MUXED_OUT pin is a latched output. It is latched when MUX_SELECT_0 = 1. It is transparent when the MUX_SELECT_0 = 0. The data sent out on the NON_MUXED_OUT output is the 6th most significant bit of the non-volatile register. Whether this comes from the non-volatile register 0 or non-volatile register 1 depends on the command code or the external mux-select pins. After a valid I2C write operation to the EEPROM, the part cannot be addressed via the I2C for 3.6 ms. If the part is addressed prior to this time, the part will not acknowledge its address. NOTE: 1. To ensure data integrity, the non-volatile register must be internally write protected when VDD to the I2C bus is powered down or VDD to the component is dropped below normal operating levels. 2004 May 19 5 Philips Semiconductors Product data sheet Dual 5-bit multiplexed 1-bit latched I2C EEPROM DIP switch PCA9560 CONVERSION FROM THE PCA9559 TO THE PCA9560 The PCA9560 is a drop in replacement to the PCA9559 with no software modifications. The PCA9559 has only one MUX_SELECT pin to choose between the MUX_IN values and the single non-volatile register. Since the PCA9560 has two internal non-volatile registers, if Register 1 is left to all 0’s (default condition) then the MUX_SELECT_1 pin can function the same as the PCA9559 OVERRIDE # pin and MUX_SELECT_0 pin can function the same as the PCA9559 MUX_IN pin. The PCA9560 can read the MUX_IN_X values via I2C that the PACA9559 cannot do. Another difference is that the MUX_SELECT_X control pins can be overridden by I2C. To replace the PCA9559 with the PCA9560, the function table for the MUX_OUT outputs and the NON_MUXED_OUT output must stay the same and the MUX_SELECT pin functions should not be overridden by I2C. EXTERNAL CONTROL SIGNALS The Write Protect (WP) input is used to control the ability to write the content of the non-volatile registers. If the WP signal is logic 0, the I2C bus will be able to write the contents of the non-volatile registers. If the WP signal is logic 1, data will not be allowed to be written into the non-volatile registers. In this case, the slave address and the command code will be acknowledged but the following data bytes will not be acknowledged and the EEPROM is not updated. 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 WP, MUX_IN*, MUX_SELECT_0, and MUX_SELECT_1 signals have internal pull-up resistors. See the DC and AC Characteristics for hysteresis and signal spike suppression figures.

This table is valid when not overridden by I2C control register. POWER-ON RESET (POR) When power is applied to VDD, an internal power-on reset holds the PCA9560 in a reset state until VDD has reached VPOR. At that point, the reset condition is released and the PCA9560 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 MUX_SELECT_0 and MUX_SELECT_1 logic levels, selecting either the MUX_IN input pins or one of the two 6-bit EEPROMs – the previously stored values in the EEPROM registers/current MUX_IN pin values as shown in the Function Table 2004 May 19 6 Philips Semiconductors Product data sheet Dual 5-bit multiplexed 1-bit latched I2C EEPROM DIP switch CHARACTERISTICS OF THE I2C-BUS PCA9560 The I2C-bus is for 2-way, 2-line communication between different ICs or modules. The two lines are a serial data line (SDA) and a serial clock line (SCL). Both lines must be connected to a positive supply via a pull-up resistor when connected to the output stages of a device. Data transfer may be initiated only when the bus is not busy. Bit transfer One data bit is transferred during each clock pulse. The data on the SDA line must remain stable during the HIGH period of the clock pulse as changes in the data line at this time will be interpreted as control signals (see Figure 5). SDA SCL data line stable; data valid change of data allowed SW00363 Figure 5. Bit transfer Start and stop conditions Both data and clock lines remain HIGH when the bus is not busy. A HIGH-to-LOW transition of the data line, while the clock is HIGH is defined as the start condition (S). A LOW-to-HIGH transition of the data line while the clock is HIGH is defined as the stop condition (P) (see Figure 6). System configuration A device generating a message is a ‘transmitter’, a device receiving is the ‘receiver’. The device initiates a transfer is the ‘master’ and the devices which are controlled by the master are the ‘slaves’ (see Figure 7).

Each byte of eight bits is followed by one acknowledge bit. The acknowledge bit is a HIGH-level put on the bus by the transmitter whereas the master generates an extra acknowledge related clock pulse. A slave receiver which is addressed must generate an acknowledge after the reception of each byte. Also a master must generate an acknowledge after the reception of each byte that has been clocked out of the slave transmitter. The device that acknowledges has to pull down the SDA line during the acknowledge clock pulse, so that the SDA line is stable LOW during the HIGH period of the acknowledge related clock pulse, set-up and hold times must be taken into account. A receiver must signal an end of data to the transmitter by not generating an acknowledge on the last byte that has been clocked out of the slave. In this event, the transmitter must leave the data line HIGH to enable the master to generate a stop condition.
