PCA9513A; PCA9514A Hot swappable I2C-bus and SMBus bus buffer Rev. 01 -- 11 October 2005 Product data sheet 1. General description The PCA9513A and PCA9514A are hot swappable I2C-bus and SMBus buffers that allow I/O card insertion into a live backplane without corrupting the data and clock buses. Control circuitry prevents the backplane from being connected to the card until a stop command or bus idle occurs on the backplane without bus contention on the card. When the connection is made, the PCA9513A and PCA9514A provides bidirectional buffering, keeping the backplane and card capacitances isolated. Rise time accelerator circuitry allows the use of weaker DC pull-up currents while still meeting rise time requirements. The PCA9513A and PCA9514A incorporates a digital ENABLE input pin, which enables the device when asserted HIGH and forces the device into a Low current mode when asserted LOW, and an open-drain READY output pin, which indicates that the backplane and card sides are connected together (HIGH) or not (LOW). The PCA9513A supplies a 92 A current source to SCLIN and SDAIN pins in lieu of using pull-up resistors which is ideal for multidrop bus applications. Including the current source in the device provides for a consistent RC time constant as cards are removed and inserted into the backplane. The current source is high-impedance whenever the pin voltage is greater than the part VCC. The PCA9513A and PCA9514A rise time accelerator threshold is 0.8 V to provide better noise margin over the PCA9511A which is set to 0.6 V. Remark: The dynamic offset design of the PCA9510A/11A/12A/13A/14A I/O drivers allow them to be connected to another PCA9510A/11A/12A/13A/14A device in series or in parallel and to the A side of the PCA9517. The PCA9510A/11A/12A/13A/14A cannot connect to the static offset I/Os used on the PCA9515/15A/16/16A/18 or PCA9517 B side or P82B96 Sx/y side. 2.

Functional description Refer to Figure 1 "Block diagram of PCA9513A" and Figure 2 "Block diagram of PCA9514A". 8.1 Start-up An undervoltage and initialization circuit holds the parts in a disconnected state which presents high-impedance to all SDAn and SCLn pins during power-up. A LOW on the ENABLE pin also forces the parts into the low current disconnected state when the ICC is essentially zero. As the power supply is brought up and the ENABLE is HIGH or the part is powered and the ENABLE is taken from LOW to HIGH it enters an initialization state where the internal references are stabilized and the 92 A input pull-ups (on the PCA9513A) is enabled. At the end of the initialization state the `Stop Bit And Bus Idle' detect circuit is enabled.

Product data sheet Rev. 01 -- 11 October 2005 5 of 25 Philips Semiconductors PCA9513A; PCA9514A Hot swappable I2C-bus and SMBus bus buffer HIGH for the bus idle time or when all pins are HIGH and a STOP condition is seen on the SDAIN and SCLIN pins, SDAIN is connected to SDAOUT and SCLIN is connected to SCLOUT. A 92 A pull-up current source on SDAIN and SCLIN of the PCA9513A is activated during the initialization state and remains active until the power is removed or the ENABLE pin is taken LOW. When the 92 A pull-up is active it will become high-impedance any time the pin voltage is greater than VCC, otherwise it provides current to pull the pin up to VCC. 8.2 Connect circuitry Once the connection circuitry is activated, the behavior of SDAIN and SDAOUT as well as SCLIN and SCLOUT become identical with each acting as a bidirectional buffer that isolates the input capacitance from the output bus capacitance while communicating the logic levels. A LOW forced on either SDAIN or SDAOUT will cause the other pin to be driven to a LOW by the part. The same is also true for the SCLn pins. Noise between 0.7VCC and VCC is generally ignored because a falling edge is only recognized when it falls below 0.7VCC with a slew rate of at least 1.25 V/s. When a falling edge is seen on one pin, the other pin in the pair turns on a pull-down driver that is referenced to a small voltage above the falling pin. The driver will pull the pin down at a slew rate determined by the driver and the load initially, because it does not start until the first falling pin is below 0.7VCC. The first falling pin may have a fast or slow slew rate, if it is faster than the pull-down slew rate then the initial pull-down rate will continue. If the first falling pin has a slow slew rate then the second pin will be pulled down at its initial slew rate only until it is just above the first pin voltage then they will both continue down at the slew rate of the first. Once both sides are LOW they will remain LOW until all the external drivers have stopped driving LOWs. If both sides are being driven LOW to the same value for instance, 10 mV by external drivers, which is the case for clock stretching and is typically the case for acknowledge, and one side external driver stops driving that pin will rise until the internal driver pulls it down to the offset voltage. When the last external driver stops driving a LOW, that pin will rise up and settle out just above the other pin as both rise together with a slew rate determined by the internal slew rate control and the RC time constant. As long as the slew rate is at least 1.25 V/s, when the pin voltage exceeds 0.8 V for the PCA9513A and PCA9514A, the rise time accelerators' circuits are turned on and the pull-down driver is turned off. 8.3 Maximum number of devices in series Each buffer adds about 0.1 V dynamic level offset at 25 C with the offset larger at higher temperatures. Maximum offset voltage (Voffset) is 0.150 V with a 10 k pull-up resistor. The LOW level at the signal origination end (master) is dependent upon the load and the only specification point is the I2C-bus specification of 3 mA will produce VOL < 0.4 V, although if lightly loaded the VOL may be 0.1 V. Assuming VOL = 0.1 V and Voffset = 0.1 V, the level after four buffers would be 0.5 V, which is only about 0.3 V below the threshold of the rising edge accelerator (about 0.8 V). With great care a system with four buffers may work, but as the VOL moves up from 0.1 V, noise or bounces on the line will result in firing the rising edge accelerator thus introducing false clock edges. Generally it is recommended to limit the number of buffers in series to two, and to keep the load light to minimize the offset. PCA9513A_PCA9514A_1 (c) Koninklijke Philips Electronics N.V. 2005.

Product data sheet Rev. 01 -- 11 October 2005 6 of 25 Philips Semiconductors PCA9513A; PCA9514A Hot swappable I2C-bus and SMBus bus buffer The PCA9510A (rise time accelerator is permanently disabled) and the PCA9512A (rise time accelerator can be turned off) are a little different with the rise time accelerator turned off because the rise time accelerator will not pull the node up, but the same logic that turns on the accelerator turns the pull-down off. If the VIL is above 0.6 V and a rising edge is detected, the pull-down will turn off and will not turn back on until a falling edge is detected. buffer A MASTER common node buffer B SLAVE B buffer C SLAVE C 002aab581 Fig 5. System with 3 buffers connected to common node Consider a system with three buffers connected to a common node and communication between the Master and Slave B that are connected at either end of buffer A and buffer B in series as shown in Figure 5. Consider if the VOL at the input of buffer A is 0.3 V and the VOL of Slave B (when acknowledging) is 0.4 V with the direction changing from Master to Slave B and then from Slave B to Master. Before the direction change you would observe VIL at the input of buffer A of 0.3 V and its output, the common node, is 0.4 V. The output of buffer B and buffer C would be 0.5 V, but Slave B is driving 0.4 V, so the voltage at Slave B is 0.4 V. The output of buffer C is 0.5 V. When the Master pull-down turns off, the input of buffer A rises and so does its output, the common node, because it is the only part driving the node. The common node will rise to 0.5 V before buffer B's output turns on, if the pull-up is strong the node may bounce. If the bounce goes above the threshold for the rising edge accelerator 0.6 V the accelerators on both buffer A and buffer C will fire contending with the output of buffer B. The node on the input of buffer A will go HIGH as will the input node of buffer C. After the common node voltage is stable for a while the rising edge accelerators will turn off and the common node will return to 0.5 V because the buffer B is still on. The voltage at both the Master and Slave C nodes would then fall to 0.6 V until Slave B turned off. This would not cause a failure on the data line as long as the return to 0.5 V on the common node (0.6 V at the Master and Slave C) occurred before the data setup time. If this were the SCL line, the parts on buffer A and buffer C would see a false clock rather than a stretched clock, which would cause a system error. The PCA9513A and PCA9514A rise time accelerator threshold is 0.8 V, so there is 0.2 V more noise margin. 8.4 Propagation delays The delay for a rising edge is determined by the combined pull-up current from the bus resistors and the rise time accelerator current source and the effective capacitance on the lines. If the pull-up currents are the same, any difference in rise time is directly proportional to the difference in capacitance between the two sides. The tPLH may be negative if the output capacitance is less than the input capacitance and would be positive if the output capacitance is larger than the input capacitance, when the currents are the same.

Product data sheet Rev. 01 -- 11 October 2005 7 of 25 Philips Semiconductors PCA9513A; PCA9514A Hot swappable I2C-bus and SMBus bus buffer The tPHL can never be negative because the output does not start to fall until the input is below 0.7VCC, and the output turn on has a non-zero delay, and the output has a limited maximum slew rate, and even if the input slew rate is slow enough that the output catches up it will still lag the falling voltage of the input by the offset voltage. The maximum tPHL occurs when the input is driven LOW with zero delay and the output is still limited by its turn-on delay and the falling edge slew rate. The output falling edge slew rate is a function of the internal maximum slew rate which is a function of temperature, VCC and process, as well as the load current and the load capacitance. 8.5 Rise time accelerators During positive bus transitions a 2 mA current source is switched on to quickly slew the SDA and SCL lines HIGH once the input level of 0.8 V for the PCA9513A and PCA9514A are exceeded. The rising edge rate should be at least 1.25 V/s to guarantee turn on of the accelerators. 8.6 READY digital output This pin provides a digital flag which is LOW when either ENABLE is LOW or the start-up sequence described earlier in this section has not been completed. READY goes HIGH when ENABLE is HIGH and start-up is complete. The pin is driven by an open-drain pull-down capable of sinking 3 mA while holding 0.4 V on the pin. Connect a resistor of 10 k to VCC to provide the pull-up. 8.7 ENABLE low current disable Grounding the ENABLE pin disconnects the backplane side from the card side, disables the rise time accelerators, drives READY LOW, disables the bus precharge circuitry, and puts the part in a low current state. When the pin voltage is driven all the way to VCC, the part waits for data transactions on both the backplane and card sides to be complete before reconnecting the two sides. 8.8 Resistor pull-up value selection The system pull-up resistors must be strong enough to provide a positive slew rate of 1.25 V/s on the SDAn and SCLn pins, in order to activate the boost pull-up currents during rising edges. Choose maximum resistor value using the formula: 3 V CC ( min ) - 0.6 R PU 800 x 10 ---------------------------------- - C where RPU is the pull-up resistor value in , VCC(min) is the minimum VCC voltage in volts, and C is the equivalent bus capacitance in picofarads. In addition, regardless of the bus capacitance, always choose RPU 16 k for VCC = 5.5 V maximum, RPU 24 k for VCC = 3.6 V maximum. The start-up circuitry requires logic HIGH voltages on SDAOUT and SCLOUT to connect the backplane to the card, and these pull-up values are needed to overcome the precharge voltage. See the curves in Figure 6 and Figure 7 for guidance in resistor pull-up selection. PCA9513A_PCA9514A_1 (c) Koninklijke Philips Electronics N.V. 2005. All rights reserved.

Bus requirements for 5 V systems 8.9 Hot swapping and capacitance buffering application Figure 8 through Figure 11 illustrate the usage of the PCA9513A and PCA9514A in applications that take advantage of both its hot swapping and capacitance buffering features. In all of these applications, note that if the I/O cards were plugged directly into the backplane, all of the backplane and card capacitances would add directly together, making rise and fall time requirements difficult to meet. Placing a bus buffer on the edge of each card, however, isolates the card capacitance from the backplane. For a given I/O card, the PCA9513A and PCA9514A drive the capacitance of everything on the card, and the backplane must drive only the capacitance of the bus buffer, which is less than 10 pF, the connector, trace, and all additional cards on the backplane. See Application Note AN10160, `Hot Swap Bus Buffer' for more information on applications and technical assistance. PCA9513A_PCA9514A_1 (c) Koninklijke Philips Electronics N.V. 2005.

Soldering 14.1 Introduction to soldering surface mount packages This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our Data Handbook IC26; Integrated Circuit Packages (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended. 14.2 Reflow soldering Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. Several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 seconds and 200 seconds depending on heating method. Typical reflow peak temperatures range from 215 C to 270 C depending on solder paste material. The top-surface temperature of the packages should preferably be kept: * below 225 C (SnPb process) or below 245 C (Pb-free process) - for all BGA, HTSSON..T and SSOP..T packages - for packages with a thickness 2.5 mm - for packages with a thickness < 2.5 mm and a volume 350 mm3 so called thick/large packages. * below 240 C (SnPb process) or below 260 C (Pb-free process) for packages with a thickness < 2.5 mm and a volume < 350 mm3 so called small/thin packages. Moisture sensitivity precautions, as indicated on packing, must be respected at all times. 14.3 Wave soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. To overcome these problems the double-wave soldering method was specifically developed. If wave soldering is used the following conditions must be observed for optimal results: * Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. * For packages with leads on two sides and a pitch (e): - larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; PCA9513A_PCA9514A_1 (c) Koninklijke Philips Electronics N.V. 2005. All rights reserved. Product data sheet Rev. 01 -- 11 October 2005 21 of 25 Philips Semiconductors PCA9513A; PCA9514A Hot swappable I2C-bus and SMBus bus buffer - smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves at the downstream end. * For packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. 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. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 14.4 Manual soldering Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 seconds to 5 seconds between 270 C and 320 C. 14.5 Package related soldering information Table 6: Package [1] BGA, HTSSON..T [3], LBGA, LFBGA, SQFP, SSOP..T [3], TFBGA, VFBGA, XSON DHVQFN, HBCC, HBGA, HLQFP, HSO, HSOP, HSQFP, HSSON, HTQFP, HTSSOP, HVQFN, HVSON, SMS PLCC [5], SO, SOJ LQFP, QFP, TQFP SSOP, TSSOP, VSO, VSSOP CWQCCN..L [8], PMFP [9], WQCCN..L [8] [1] [2] Suitability of surface mount IC packages for wave and reflow soldering methods Soldering method Wave not suitable not suitable [4] Reflow [2] suitable suitable suitable not not recommended [5] [6] recommended [7] suitable suitable suitable not suitable not suitable For more detailed information on the BGA packages refer to the (LF)BGA Application Note (AN01026); order a copy from your Philips Semiconductors sales office. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods. These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature exceeding 217 C 10 C measured in the atmosphere of the reflow oven. The package body peak temperature must be kept as low as possible. [3] PCA9513A_PCA9514A_1 (c) Koninklijke Philips Electronics N.V. 2005. All rights reserved. Product data sheet Rev. 01 -- 11 October 2005 22 of 25 Philips Semiconductors PCA9513A; PCA9514A Hot swappable I2C-bus and SMBus bus buffer [4] These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. Wave soldering is suitable for LQFP, QFP and TQFP packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered pre-mounted on flex foil. However, the image sensor package can be mounted by the client on a flex foil by using a hot bar soldering process. The appropriate soldering profile can be provided on request. Hot bar soldering or manual soldering is suitable for PMFP packages. [5] [6] [7] [8] [9] 15.
