2003 nov 06 7 philips semiconductors product speci?cation dual ic card interface tda8020hl functional description throughout this specification, it is assumed that the reader is familiar with iso 7816 terminology. supply the tda8020hl operates with a supply voltage from 2.7 to 6.5 v. an integrated voltage supervisor ensures that no spike appears on cards contacts during power-on or off. the supervisor also initializes the device, and forces an automatic emergency deactivation of the contacts in the event of a supply drop-out. as long as the supply voltage is below the threshold voltage v th1 , the capacitor c del remains uncharged. when the supply voltage reaches v th1 and v hys1 , then c del is charged with a small current source of approximately 2 m a. when the voltage on c del reaches v th2 , then the supervisor is no longer active. as long as the supervisor is active (pin irq is low), bit supl in the status register is set. when pin irq goes high the voltage supervisor becomes inactive (see fig.3). separate supply pins are used for the dc-to-dc converter, allowing specific decoupling for counteracting the noise the switching transistors may induce on the supply. a specific reference supply voltage, v ddi , is used for the interface signals clkin1, clkin2, i/o1uc, i/o2uc, sad0, sad1, scl, sda and irq, which can be lower than v dd (minimum 1.5 v), thus allowing direct control with a low voltage supplied device. pins scl, sda and irq are open-drain outputs, and may be externally pulled up to a voltage higher than v dd . handbook, full pagewidth t w t w fce835 bus ok bus not responding bus not responding bus not responding bus ok status read after event v dd v th1 + v hys1 v th1 v th2 v cdel irq fig.3 voltage supervisor.
2003 nov 06 8 philips semiconductors product speci?cation dual ic card interface tda8020hl dc-to-dc converter v cc1 is the supply voltage for card 1 contacts and v cc2 is the supply voltage for card 2 contacts. card 1 and card 2 may be independently powered-down, powered at 5 v or powered at 3 v. a capacitor type step-up converter is used for generating these voltages. this step-up converter acts either as a doubler, tripler or follower. an hysteresis of 100 mv is present on the different threshold voltages. if v cc is the maximum value of v cc1 and v cc2 , then there are 5 possible situations: v dd < 3.4 v and v cc = 3 v: in this case, the dc-to-dc converter acts as a doubler with a regulation of approximately 4.0 v v dd < 3.4 v and v cc = 5 v: in this case, the dc-to-dc converter acts as a tripler with a regulation of approximately 5.5 v v dd > 3.5 v and v cc = 3 v: in this case, the dc-to-dc converter acts as a follower: v dd is applied on v up 5.8v>v dd > 3.5 v and v cc = 5 v: in this case, the dc-to-dc converter acts as a doubler with a regulation of approximately 5.5 v v dd > 5.9 v and v cc = 5 v: in this case, the dc-to-dc converter acts as a follower and v dd is applied on v up . the output voltage, v up , is fed internally to the v cc generators. v cc1 ,v cc2 and cgnd1, cgnd2 are used as a reference for all other cards contacts. the sum of i cc1 and i cc2 shall not exceed 80 ma, which means that when a card is drawing its maximum current (around 60 ma at v cc = 5 v, 55 ma at v cc = 3 v), the other card should be set in low power consumption mode (less than 20 or 25 ma). note that during the card advice to receive (atr) process, the current may be maximum; so, a card should only be activated if the other card draws less than 20 or 25 ma. the dc-to-dc converter is supplied via separate supply pins v dda and agnd to allow decoupling separate from the other supply pins. during normal operation or activation, each card is allowed to draw independently a current of up to 60 ma at v cc = 5 v or up to 55 ma at v cc = 3 v, with a supply voltage from 2.7 v up to 6.5 v provided the sum of i cc1 and i cc2 does not exceed 80 ma. if v dd > 3 v, for 5 v cards, then both cards can draw up to 60 ma at the same time. if v dd > 3 v, for 3 v cards, then both cards can draw up to 55 ma at the same time. i 2 c-bus a 400 khz i 2 c-bus slave interface is used for configuring the device and reading the status. i 2 c- bus protocol the i 2 c-bus is for 2-way, 2-line communication between different ics or modules. the serial bus consists of two bidirectional lines; one for data (sda), and one for the clock (scl). both the sda and scl lines must be connected to a positive supply voltage via a pull-up resistor. the following protocol has been defined: data transfer may be initiated only when the bus is not busy during data transfer, the data line must remain stable whenever the clock line is high. changes in the data line while the clock line is high will be interpreted as control signals. b us conditions the following bus conditions have been defined: bus not busy: both data and clock lines remain high start data transfer: a change in the state of the data line, from high-to-low, while the clock is high, defines the start condition stop data transfer: a change in the state of the data line, from low-to-high, while the clock is high, defines the stop condition data valid: the state of the data line represents valid data when, after a start condition, the data line is stable for the duration of the high period of the clock signal. there is one clock pulse per data bit. d ata transfer each data transfer is initiated with a start condition and terminated with a stop condition. data transfer is unlimited in the read mode. the information is transmitted in bytes and each receiver acknowledges with a ninth bit. the tda8020hl operates in standard mode (100 khz clock rate) and fast mode (400 khz clock rate) defined in the i 2 c-bus specification. by definition, a device that sends a signal is called a transmitter, and the device which receives the signal is called a receiver. the device which controls the signal is
2003 nov 06 9 philips semiconductors product speci?cation dual ic card interface tda8020hl called the master. the devices that are controlled by the master are called slaves. each byte is followed by one high-level acknowledge bit asserted by the transmitter. the master generates an extra acknowledge related clock pulse. the slave receiver which is addressed is obliged to generate an acknowledge after the reception of each byte. the master receiver 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 in such a way 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 master receiver must signal an end of data to the slave 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 generation of the stop condition. see chapter characteristics for timing information. d evice addressing each device has 2 different addresses, one for each card. an application can use up to four devices in parallel by the use of address selection pins sad0 and sad1. pins sad0 and sad1 are externally hardwired to v dd or gnd; sad0 specifies address bit a0, sad1 specifies address bit a1; address bit r/ w specifies either read or write operation: logic 1 = read, logi c 0 = write (see tables 1 and 2). table 1 proposed device address bit allocations table 2 proposed i 2 c-bus addresses for 4 devices in parallel device address bits 76543210 tda8020hl 0 1 0 0 0/1 a1 a0 r/ w pin sad1 pin sad0 card 1 card 2 low low 40h 48h low high 42h 4ah high low 44h 4ch high high 46h 4eh

2003 nov 06 12 philips semiconductors product speci?cation dual ic card interface tda8020hl deactivation is initiated either by the system controller (reset bit start), or automatically in the event of a hardware problem or supply drop-out. with a supply drop-out both cards are deactivated at the same time. during deactivation, rst goes low, the clock is stopped and the i/o lines go low. v cc then goes low with a controlled slope and the dc-to-dc converter is stopped if no card is active. outside a session, cards contacts are forced low impedance to cgnd. d evice type tda8020hl/c2: 1. if a start bit is detected on the i/o during the first 200 clk pulses, it is ignored and the count continues. 2. if a start bit is detected whilst rst is low (between 200 and 42100 clk pulses), bits early and mute are set in the status register; rst will remain low; the software decides whether to accept the card or not. 3. if no start bit has been detected until after 42100 clk pulses, rst is set to logic 1. 4. if a start bit is detected within 370 clk pulses, bit early is set in the status register. 5. if the card does not respond within the next 42100 clk pulses, bit mute is set within the status register. this initiates a warm reset command. 6. if the card responds within the correct window period, the clk count is stopped and the system controller may send commands to the card. deactivation is initiated either by the system controller (reset bit start), or automatically in the event of a hardware problem or supply drop-out. with a supply drop-out both cards are deactivated at the same time. during deactivation, rst goes low, the clock is stopped and the i/o lines go low. v cc then goes low with a controlled slope and the dc-to-dc converter is stopped if no card is active. outside a session, cards contacts are forced low impedance to cgnd. activation sequence when the cards are inactive, v cc , clk, rst and i/o are low, with low impedance with respect to cgnd. the dc-to-dc converter is stopped. when everything is satisfactory (voltage supply, card present and no hardware problems), the system controller may initiate a card present activation sequence (see fig.4): 1. the internal oscillator changes to its high frequency (t0). 2. the dc-to-dc converter is started (t1). if one card was already active, then the dc-to-dc converter was already on, and nothing more occurs at this step. 3. v cc starts rising from 0 to 5 or 3 v with a controlled rise time of 0.14 v/ m s typical (t2). 4. i/o rises to v cc (t3); internal 14 k w pull-up resistors to v cc . 5. clk is sent to the card and rst is enabled (t4 = t act ). if the card does not respond within the first 42100 clk cycles, then rst is raised high (t5). the sequencer is clocked by f int /64 which leads to a time interval t of 25 m s typical. thus t1 = 0 to t/64; t2 = t1 + 3t/2; t3 = t1 + 7t/2 and t4 = t1 + 4t.

2003 nov 06 24 philips semiconductors product speci?cation dual ic card interface tda8020hl soldering 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. re?ow 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 and 200 seconds depending on heating method. typical reflow peak temperatures range from 215 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) C for all bga, htsson-t and ssop-t packages C for packages with a thickness 3 2.5 mm C for packages with a thickness < 2.5 mm and a volume 3 350 mm 3 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 mm 3 so called small/thin packages. moisture sensitivity precautions, as indicated on packing, must be respected at all times. 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): C 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; C 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 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. 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 to 5 seconds between 270 and 320 c.
2003 nov 06 25 philips semiconductors product speci?cation dual ic card interface tda8020hl suitability of surface mount ic packages for wave and re?ow soldering methods notes 1. 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. 2. 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 . 3. 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. 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. 5. 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. 6. wave soldering is suitable for lqfp, tqfp and qfp 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. 7. 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. 8. hot bar or manual soldering is suitable for pmfp packages. package (1) soldering method wave reflow (2) bga, htsson-t (3) , lbga, lfbga, sqfp, ssop-t (3) , tfbga, uson, vfbga not suitable suitable dhvqfn, hbcc, hbga, hlqfp, hso, hsop, hsqfp, hsson, htqfp, htssop, hvqfn, hvson, sms not suitable (4) suitable plcc (5) , so, soj suitable suitable lqfp, qfp, tqfp not recommended (5)(6) suitable ssop, tssop, vso, vssop not recommended (7) suitable pmfp (8) not suitable not suitable
