1. general description the pca9554 and pca9554a are 16-pin cmos devices that provide 8 bits of general purpose parallel input/output (gpio) expansion for i 2 c-bus/smbus applications and were developed to enhance the nxp semiconductors family of i 2 c-bus i/o expanders. the improvements include higher drive capability, 5 v i/o to lerance, lower supply current, individual i/o configuration, 400 khz clo ck 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 pca9554/pca9554a consist of an 8-bit co nfiguration register (input or output selection); 8-bit input port register, 8-bit output port register and an 8-bit polarity inversion register (active high or active lo w 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 corres ponding input port or output port register. the polarity of the read register can be invert ed with the polarity inversion register. all registers can be read by the system master. although pin-to-pin and i 2 c-bus address compatible with the pcf8574 series, software changes are required due to the enhancements and are discussed in application note an469 . the pca9554/pca9554a 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 initia lizes the device state machine. three hardware pins (a0, a1, a2) vary the fixed i 2 c-bus address and allow up to eight devices to share the same i 2 c-bus/smbus. the pca9554a is identical to the pca9554 except that the fixed i 2 c-bus address is different allowing up to sixteen of these devices (eight of each) on the same i 2 c-bus/smbus. 2. features and benefits ? operating power supply voltage range of 2.3 v to 5.5 v ? 5 v tolerant i/os ? polarity inversion register ? active low interrupt output ? low standby current ? noise filter on scl/sda inputs ? no glitch on power-up ? internal power-on reset ? 8 i/o pins which default to 8 inputs ? 0 hz to 400 khz clock frequency pca9554; pca9554a 8-bit i 2 c-bus and smbus i/o port with interrupt rev. 8 ? 26 july 2011 product data sheet

is determined by the externa lly applied logic level, normally ?1? when no external signal externally applied because of the internal pull-up resistors. 6.1.3 register 1 - output port register this register reflects the outgoing logic levels of the pins defined as outputs by register 3. bit values in this register have no effect on pi ns 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. table 4. register 0 - input port register bit description bit symbol access value description 7 i7 read only x determined by externally applied logic level 6 i6 read only x 5 i5 read only x 4 i4 read only x 3 i3 read only x 2 i2 read only x 1 i1 read only x 0 i0 read only x table 5. register 1 - output port register bit description legend: * default value. bit symbol access value description 7 o7 r 1* reflects outgoing logic levels of pins defined as outputs by register 3 6o6 r 1* 5o5 r 1* 4o4 r 1* 3o3 r 1* 2o2 r 1* 1o1 r 1* 0o0 r 1* pca9554_9554a all information provided in this document is subject to legal disclaimers. ?

typ.) to v dd . the input voltage may be raised above v dd 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 v dd or v ss . remark: at power-on reset, all registers return to default values. fig 9. simplified schematic of io0 to io7 v dd io0 to io7 output port register data configuration register dq ck q data from shift register write configuration pulse output port register dq ck write pulse polarity inversion register dq ck data from shift register write polarity pulse input port register dq ck read pulse input port register data polarity inversion register data 002aac493 ff data from shift register ff ff ff q1 q2 v ss to int 100 k pca9554_9554a all information provided in this document is subject to legal disclaimers. ?

. 13.1 introduction to soldering soldering is one of the most common methods through which packages are attached to printed circuit boards (pcbs), to form electr ical circuits. the soldered joint provides both the mechanical and the electrical connection. th ere is no single sold ering 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. 13.2 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 pr obability 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, in cluding the board finish , solder masks and vias ? package footprints, including solder thieves and orientation ? the moisture sensitivit y level of the packages ? package placement ? inspection and repair ? lead-free soldering versus snpb soldering 13.3 wave soldering key characteristics in wave soldering are: pca9554_9554a all information provided in this document is subject to legal disclaimers. ?

solder bath specifications, including temperature and impurities 13.4 reflow soldering key characteristics in reflow soldering are: ? lead-free versus snpb solderi ng; note that a lead-free reflow process usually leads to higher minimum peak temperatures (see figure 25 ) than a snpb process, thus reducing the process window ? solder paste printing issues including smearing, release, and adjusting the process window for a mix of large and small components on one board ? reflow temperature profile; this profile includ es preheat, reflow (in which the board is heated to the peak temperature) and cooling down. 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 ta b l e 11 and 12 moisture sensitivity precautions, as indicat ed on the packing, must be respected at all times. studies have shown that small packages reach higher temperatures during reflow soldering, see figure 25 . table 11. snpb eutectic process (from j-std-020c) package thickness (mm) package reflow temperature ( ?c) volume (mm 3 ) < 350 ?

. 14. soldering of throug h-hole mount packages 14.1 introduction to solderi ng through-hole mount packages this text gives a very brief insight into wave, dip and manual soldering. wave soldering is the preferred method for mounting of through-hole mount ic packages on a printed-circuit board. 14.2 soldering by dipping or by solder wave driven by legislation and environmental forc es the worldwide use of lead-free solder pastes is increasing. typical dwell time of the leads in the wave ranges from 3 seconds to 4 seconds at 250 ? c or 265 ? c, depending on solder material applied, snpb or pb-free respectively. the total contact time of successive solder waves must not exceed 5 seconds. the device may be mounted up to the seati ng plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (t stg(max) ). if the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. 14.3 manual soldering apply the soldering iron (24 v or less) to the lead(s) of the package, either below the seating plane or not more than 2 mm above it. if the temperature of the soldering iron bit is less than 300 ? c it may remain in contact for up to 10 seconds. if the bit temperature is between 300 ? c and 400 ? c, contact may be up to 5 seconds. msl: moisture sensitivity level fig 25. temperature profiles for large and small components 001aac844 temperature time minimum peak temperature = minimum soldering temperature maximum peak temperature = msl limit, damage level peak temperature pca9554_9554a all information provided in this document is subject to legal disclaimers. ?
