PCA9534 8-bit I2C-bus and SMBus low power I/O port with interrupt Rev. 03 — 6 November 2006 Product data sheet 1. General description The PCA9534 is a 16-pin CMOS device that provide 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications and was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders. The improvements include higher drive capability, 5 V I/O tolerance, lower supply current, individual I/O configuration, 400 kHz clock frequency, and smaller packaging. I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc. The PCA9534 consists of an 8-bit Configuration register (Input or Output selection); 8-bit Input register, 8-bit Output register and an 8-bit Polarity Inversion register (active HIGH or active LOW operation). The system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding Input or Output register. The polarity of the Input Port register can be inverted with the Polarity Inversion register. All registers can be read by the system master. Although pin-to-pin and I2C-bus address compatible with the PCF8574 series, software changes are required due to the enhancements and are discussed in Application Note AN469. The PCA9534 is identical to the PCA9554 except for the removal of the internal I/O pull-up resistor which greatly reduces power consumption when the I/Os are held LOW. The PCA9534 open-drain interrupt output is activated when any input state differs from its corresponding input port register state and is used to indicate to the system master that an input state has changed. The power-on reset sets the registers to their default values and initializes the device state machine. Three hardware pins (A0, A1, A2) vary the fixed I2C-bus address and allow up to eight devices to share the same I2C-bus/SMBus. 2.

VSS pin must be connected to supply ground for proper device operation.

It is used as a pointer to determine which of the following registers will be written or read. 6.1.2 Register 0 - Input Port register This register is a read-only port. It reflects the incoming logic levels of the pins, regardless of whether the pin is defined as an input or an output by Register 3. Writes to this register have no effect. The default ‘X’ is determined by the externally applied logic level. PCA9534_3 Product data sheet © NXP B.V. 2006. All rights reserved.

Bit values in this register have no effect on pins defined as inputs. Reads from this register return the value that is in the flip-flop controlling the output selection, not the actual pin value.

If a bit in this register is set (written with ‘1’), the corresponding Input Port data is inverted.

If a bit in this register is set, the corresponding port pin is enabled as an input with high-impedance output driver. If a bit in this register is cleared, the corresponding port pin is enabled as an output. At reset, the I/Os are configured as inputs. Table 7.

At that point, the reset condition is released and the PCA9534 registers and state machine will initialize to their default states. Thereafter, VDD must be lowered below 0.2 V to reset the device. For a power reset cycle, VDD must be lowered below 0.2 V and then restored to the operating voltage. 6.3 Interrupt output The open-drain interrupt output is activated when one of the port pins change state and the pin is configured as an input. The interrupt is deactivated when the input returns to its previous state or the Input Port register is read. Note that changing an I/O from and output to an input may cause a false interrupt to occur if the state of the pin does not match the contents of the Input Port register. 6.4 I/O port When an I/O is configured as an input, FETs Q1 and Q2 are off, creating a high-impedance input. The input voltage may be raised above VDD to a maximum of 5.5 V. If the I/O is configured as an output, then either Q1 or Q2 is enabled, depending on the state of the Output Port register. Care should be exercised if an external voltage is applied to an I/O configured as an output because of the low-impedance paths that exist between the pin and either VDD or VSS.

Data is read from the PCA9534 registers using the Read mode as shown in Figure 10 and Figure 11. These devices do not implement an auto-increment function, so once a command byte has been sent, the register which was addressed will continue to be accessed by reads until a new command byte has been sent.

Typical application 7.1 Minimizing IDD when the I/O us used to control LEDs When the I/Os are used to control LEDs, they are normally connected to VDD through a resistor as shown in Figure 12. Since the LED acts as a diode, when the LED is off the I/O VI is about 1.2 V less than VDD. The supply current, IDD, increases as VI becomes lower than VDD. Designs needing to minimize current consumption, such as battery power applications, should consider maintaining the IOn pins greater than or equal to VDD when the LED is off. Figure 13 shows a high value resistor in parallel with the LED. Figure 14 shows VDD less than the LED supply voltage by at least 1.2 V. Both of these methods maintain the I/O VI at or above VDD and prevents additional supply current consumption when the LED is off. PCA9534_3 Product data sheet © NXP B.V. 2006. All rights reserved.

Handling information Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be completely safe you must take normal precautions appropriate to handling integrated circuits. 14. Soldering This text provides a very brief insight into a complex technology. A more in-depth account of soldering ICs can be found in Application Note AN10365 “Surface mount reflow soldering description”. 14.1 Introduction to soldering Soldering is one of the most common methods through which packages are attached to Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both the mechanical and the electrical connection. There is no single soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high densities that come with increased miniaturization. 14.2 Wave and reflow soldering Wave soldering is a joining technology in which the joints are made by solder coming from a standing wave of liquid solder. The wave soldering process is suitable for the following: • Through-hole components • Leaded or leadless SMDs, which are glued to the surface of the printed circuit board Not all SMDs can be wave soldered. Packages with solder balls, and some leadless packages which have solder lands underneath the body, cannot be wave soldered. Also, leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered, due to an increased probability of bridging. The reflow soldering process involves applying solder paste to a board, followed by component placement and exposure to a temperature profile. Leaded packages, packages with solder balls, and leadless packages are all reflow solderable. Key characteristics in both wave and reflow soldering are: • • • • • • Board specifications, including the board finish, solder masks and vias Package footprints, including solder thieves and orientation The moisture sensitivity level of the packages Package placement Inspection and repair Lead-free soldering versus PbSn soldering 14.3 Wave soldering Key characteristics in wave soldering are: PCA9534_3 Product data sheet © NXP B.V. 2006.

It is imperative that the peak temperature is high enough for the solder to make reliable solder joints (a solder paste characteristic). In addition, the peak temperature must be low enough that the packages and/or boards are not damaged. The peak temperature of the package depends on package thickness and volume and is classified in accordance with Table 12 and 13 Table 12. SnPb eutectic process (from J-STD-020C) Package thickness (mm) Package reflow temperature (°C) Volume (mm3) < 350 ≥ 350 < 2.5 235 220 ≥ 2.5 220 220 Table 13.

Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure 23. PCA9534_3 Product data sheet © NXP B.V. 2006. All rights reserved.
