D: h rial Data I/O pin rcivs input data and transmits data stord in EEROM. In transmit mod, this pin is opn drain. Data is acquird on th positiv dg, and is dlivrd on th ngativ dg of L. 0, 1 and 2 : h ddrss inputs st th dvic addrss whn cascading multipl dvics. Whn not drivn, ths pins ar pulld LOW intrnally. h 24164 can b mad compatibl with th 2416 by tying 2, 1 and 0 to V or by laving 2, 1 and 0 float. W: h Writ rotct input pin inhibits all writ oprations, whn pulld HIGH. Whn not drivn, this pin is pulld LOW intrnally. Functional Dscription h 24164 supports th Intr Intgratd ircuit (I 2 ) Bus data transmission protocol, which dfins a dvic that snds data to th bus as a transmittr and a dvic rciving data as a rcivr. Data flow is controlld by a Mastr dvic, which gnrats th srial clock and all R and O conditions. h 24164 acts as a lav dvic. Mastr and lav altrnat as ithr transmittr or rcivr. I 2 Bus rotocol h I 2 bus consists of two wirs, L and D. h two wirs ar connctd to th V supply via pull up rsistors. Mastr and lav dvics connct to th 2 wir bus via thir rspctiv L and D pins. h transmitting dvic pulls down th D lin to transmit a 0 and rlass it to transmit a 1. Data transfr may b initiatd only whn th bus is not busy (s.. haractristics). During data transfr, th D lin must rmain stabl whil th L lin is HIGH. n D transition whil L is HIGH will b intrprtd as a R or O condition (Figur 2). h R condition prcds all commands. It consists of a HIGH to LOW transition on D whil L is HIGH. h R acts as a wak up call to all rcivrs. bsnt a R, a lav will not rspond to commands. h O condition complts all commands. It consists of a LOW to HIGH transition on D whil L is HIGH. Dvic ddrssing h bus Mastr bgins a transmission by snding a R condition. h Mastr thn snds th addrss of th particular lav dvic it is rqusting. h most significant bit of th 8 bit slav addrss is fixd as 1. (s Figur 3). h nxt thr significant bits ( 2, 1, 0 ) ar th dvic addrss bits and dfin which dvic or which part of th dvic th Mastr is accssing (h 1 bit must b th complimnt of th 1 input pin signal). Up to ight 24164 dvics may b individually addrssd by th systm. h nxt thr bits ar usd as th thr most significant bits of th data word addrss. h last bit of th slav addrss spcifis whthr a Rad or Writ opration is to b prformd. Whn this bit is st to 1, a Rad opration is slctd, and whn st to 0, a Writ opration is slctd. cknowldg ftr procssing th lav addrss, th lav rsponds with an acknowldg () by pulling down th D lin during th 9 th clock cycl (Figur 4). h lav will also acknowldg th addrss byt and vry data byt prsntd in Writ mod. In Rad mod th lav shifts out a data byt, and thn rlass th D lin during th 9 th clock cycl. s long as th Mastr acknowldgs th data, th lav will continu transmitting. h Mastr trminats th sssion by not acknowldging th last data byt (No) and by issuing a O condition.

24164 WRIE OERION Byt Writ In Byt Writ mod, th Mastr snds th R condition and th lav addrss with th R/W bit st to zro to th lav. ftr th lav gnrats an acknowldg, th Mastr snds th byt addrss that is to b writtn into th addrss pointr of th 24164. ftr rciving anothr acknowldg from th lav, th Mastr transmits th data byt to b writtn into th addrssd mmory location. h 24164 dvic will acknowldg th data byt and th Mastr gnrats th O condition, at which tim th dvic bgins its intrnal Writ cycl to nonvolatil mmory (Figur 6). Whil this intrnal cycl is in progrss (t WR ), th D output will b tri statd and th 24164 will not rspond to any rqust from th Mastr dvic (Figur 7). ag Writ h 24164 writs up to 16 byts of data in a singl writ cycl, using th ag Writ opration (Figur 8). h ag Writ opration is initiatd in th sam mannr as th Byt Writ opration, howvr instad of trminating aftr th data byt is transmittd, th Mastr is allowd to snd up to fiftn additional byts. ftr ach byt has bn transmittd th 24164 will rspond with an acknowldg and intrnally incrmnts th four low ordr addrss bits. h high ordr bits that dfin th pag addrss rmain unchangd. If th Mastr transmits mor than sixtn byts prior to snding th O condition, th addrss countr wraps around to th bginning of pag and prviously transmittd data will b ovrwrittn. Onc all sixtn byts ar rcivd and th O condition has bn snt by th Mastr, th intrnal Writ cycl bgins. t this point all rcivd data is writtn to th 24164 in a singl writ cycl. cknowldg olling h acknowldg () polling routin can b usd to tak advantag of th typical writ cycl tim. Onc th stop condition is issud to indicat th nd of th host s writ opration, th 24164 initiats th intrnal writ cycl. h polling can b initiatd immdiatly. his involvs issuing th start condition followd by th slav addrss for a writ opration. If th 24164 is still busy with th writ opration, No will b rturnd. If th 24164 has compltd th intrnal writ opration, an will b rturnd and th host can thn procd with th nxt rad or writ opration. Hardwar Writ rotction With th W pin hld HIGH, th ntir mmory is protctd against Writ oprations. If th W pin is lft floating or is groundd, it has no impact on th opration of th 24164. h stat of th W pin is strobd on th last falling dg of L immdiatly prcding th first data byt (Figur 9). If th W pin is HIGH during th strob intrval, th 24164 will not acknowldg th data byt and th Writ rqust will b rjctd. Dlivry tat h 24164 is shippd rasd, i.., all byts ar FFh. 6

24164 RED OERION Immdiat Rad Upon rciving a lav addrss with th R/W bit st to 1, th 24164 will intrprt this as a rqust for data rsiding at th currnt byt addrss in mmory. h 24164 will acknowldg th lav addrss, will immdiatly shift out th data rsiding at th currnt addrss, and will thn wait for th Mastr to rspond.
