SNLS061C –MAY 2000–REVISED MARCH 2013 www.ti.com APPLICATIONS INFORMATION The MM145453 isspecificallydesignedtooperate4½ digit7-segmentdisplayswithminimalinterfacewiththe displayand datasource.Serialdatatransferfrom thedatasourcetothedisplaydriverisaccomplishedwith2 signals,serialData and Clock.Using a formatofa leading"1"followedby the33 databitsand 2 trailingdon't carebits,allowsdatatransferwithouttheneed ofan additionalData Load signal.SincetheMM145453 does not containa charactergenerator,theformattingofthesegment informationmust be done priortoinputtingthedata totheMM145453. The transferofthe33 databitsiscompleteatthefallingedge ofthe36thclockcycle,thus providingnon-multiplexed,directdrivetothedisplay.Outputschange onlyiftheserialdatabitsdifferfrom the previoustime. Figure4 shows thedatainputformat.A singlestartbitoflogical'1'precedesthe33 bitsofsegment datafora totalof34 bitsthatneed tobe definedand clockedin.Afterthe34 bitsareclockedin,2 additionalclockcycles arerequired.At the36thclockcyclean internalLOAD signalisgeneratedsynchronouslywiththerisingedge of theClockInsignal,which loadsthe33 bitsofsegment dataintheshiftregisterintothelatches.At thefalling edge ofthe36thclockcyclean internalRESET signalisgeneratedwhichclearsalltheshiftregistersforthenext setofdata.The shiftregistersare staticmaster-slaveconfiguration.There isno clearforthemasterportionof thefirstshiftregister,thusallowingcontinuousoperation.The dataduringthe35thand 36thclockcyclesis"don't care",butsettingdatatological'0'forthesetwo clockcyclesisthepreferredformat. The datainputbitsmap directlytothesegment outputpinsand thedisplay.The MM145453 does nothave any formatrestrictions,as alloutputsarecontrollable. The MM145453 has an internaloscillatorwhich can generatethe requiredclocksignalto drivethe LCD back plane.The frequencyoftheinternaloscillatorissetby a pull-upresistor(ROSC_IN ) connectedfrom theOSC_IN pin to VDD , and a capacitor(COSC_IN ) connected from the OSC_IN pin to Ground. Due to the currentsink limitationsoftheOSC_IN circuitry,thelowestrecommended resistorvalueforsettingtheoscillatorfrequencyis 9kΩ.Itwilltypicallytake2 to4 RC timeconstantstochargetheOSC_IN pinfrom near 0V towithin1V ofVDD whichisthehighthresholdvoltagepointfortheOSC_IN circuitry.An approximatecalculationoffOSC is: fOSC = 1 /(lη(VDD /1V)X R OSC_IN X C OSC_IN ) A R OSC_IN resistorvalueof 50kΩ witha C OSC_IN capacitorvalueof 0.01µF and a VDD valueof 5.00V would produce a typicaloscillatorfrequency( fOSC ) of about 1200Hz. The fOSC signalisdividedby 16 beforeitis presentedattheBP_OUT pin.For thisexample theapproximateBP_OUT frequencywillbe fOSC /16,or about 75Hz. The BP_IN pinoftheMM145453 can be used withan externallysuppliedsignal,providedithas a dutycycleof 50%. Any deviationfrom a precise50% dutycyclewillresultinan offsetvoltageon the LCD. The use of an externalclockallowssynchronizingthe displaydrivewithAC power,otherinternalclocks,or DVM integration timetoreduceinterferencefrom thedisplay.When usingan externalclockfortheback planedrivetheinternal oscillatorshouldbe disabledby connectingtheOSC_IN pindirectlytoground.Thiswillpreventpossibleinternal oscillations,and reducedevicedissipation. The MM145453 isa pinoutvariationoftheMM5453. For additionalapplicationsinformationpleaserefertothe MM5453 datasheet.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
