AT24C52 Pin Dscription SERIAL CLOCK (SCL): Th SCL input is usd to positiv dg clock data into ach EEPROM dvic and ngativ dg clock data out of ach dvic. SERIAL DATA (SDA): Th SDA pin is bidirctional for srial data transfr. This pin is opn-drain drivn and may b wir-ord with any numbr of othr opn-drain or opn collctor dvics. DEVICE/ADDRESSES (A, A0): Th A and A0 pins ar dvic addrss inputs that ar hardwird or lft not connctd for hardwar compatibility with othr AT24Cxx dvics. Whn th pins ar hardwird, as many as four 52K dvics may b addrssd on a singl bus systm (dvic addrssing is discussd in dtail undr th Dvic Addrssing sction. If th pins ar lft floating, th A and A0 pins will b intrnally pulld down to GND if th capacitiv coupling to th circuit board V CC plan is <3 pf. If coupling is >3 pf, Atml rcommnds conncting th addrss pins to GND. WRITE PROTECT (WP): Th writ protct input, whn connctd to GND, allows normal writ oprations. Whn WP is connctd high to V CC, all writ oprations to th mmory ar inhibitd. If th pin is lft floating, th WP pin will b intrnally pulld down to GND if th capacitiv coupling to th circuit board V CC plan is <3 pf. If coupling is >3 pf, Atml rcommnds conncting th pin to GND. Switching WP to V CC prior to a writ opration crats a softwar writ protct function. Mmory Organization AT24C52, 52K SERIAL EEPROM: Th 52K is intrnally organizd as 52 pags of 28-byts ach. Random word addrssing rquirs a 6-bit data word addrss. 3

Dvic Opration CLOCK and DATA TRANSITIONS: Th SDA pin is normally pulld high with an xtrnal dvic. Data on th SDA pin may chang only during SCL low tim priods (s Figur 4 on pag 7). Data changs during SCL high priods will indicat a start or stop condition as dfind blow. START CONDITION: A high-to-low transition of SDA with SCL high is a start condition which must prcd any othr command (s Figur 5 on pag 8). STOP CONDITION: A low-to-high transition of SDA with SCL high is a stop condition. Aftr a rad squnc, th stop command will plac th EEPROM in a standby powr mod (s Figur 5 on pag 8). ACKNOWLEDGE: All addrsss and data words ar srially transmittd to and from th EEPROM in 8-bit words. Th EEPROM snds a zro during th ninth clock cycl to acknowldg that it has rcivd ach word. STANDBY MODE: Th AT24C52 faturs a low powr standby mod which is nabld: a) upon powr-up and b) aftr th rcipt of th STOP bit and th compltion of any intrnal oprations. MEMORY RESET: Aftr an intrruption in protocol, powr loss or systm rst, any twowir part can b rst by following ths stps: (a) Clock up to 9 cycls, (b) look for SDA high in ach cycl whil SCL is high and thn (c) crat a start condition as SDA is high. 6 AT24C52

AT24C52 Dvic Addrssing Writ Oprations Th 52K EEPROM rquirs an 8-bit dvic addrss word following a start condition to nabl th chip for a rad or writ opration (s Figur 7 on pag 0). Th dvic addrss word consists of a mandatory, 0 squnc for th first fiv most significant bits as shown. This is common to all two-wir EEPROM dvics. Th 52K uss th two dvic addrss bits A, A0 to allow as many as four dvics on th sam bus. Ths bits must compar to thir corrsponding hardwird input pins. Th A and A0 pins us an intrnal propritary circuit that biass thm to a logic low condition if th pins ar allowd to float. Th ighth bit of th dvic addrss is th rad/writ opration slct bit. A rad opration is initiatd if this bit is high and a writ opration is initiatd if this bit is low. Upon a compar of th dvic addrss, th EEPROM will output a 0. If a compar is not mad, th dvic will rturn to a standby stat. DATA SECURITY: Th AT24C52 has a hardwar data protction schm that allows th usr to Writ Protct th whol mmory whn th WP pin is at V CC. BYTE WRITE: A writ opration rquirs two 8-bit data word addrsss following th dvic addrss word and acknowldgmnt. Upon rcipt of this addrss, th EEPROM will again rspond with a 0 and thn clock in th first 8-bit data word. Following rcipt of th 8-bit data word, th EEPROM will output a 0. Th addrssing dvic, such as a microcontrollr, thn must trminat th writ squnc with a stop condition. At this tim th EEPROM ntrs an intrnally-timd writ cycl, t WR, to th nonvolatil mmory. All inputs ar disabld during this writ cycl and th EEPROM will not rspond until th writ is complt (s Figur 8 on pag ). PAGE WRITE: Th 52K EEPROM is capabl of 28-byt pag writs. A pag writ is initiatd th sam way as a byt writ, but th microcontrollr dos not snd a stop condition aftr th first data word is clockd in. Instad, aftr th EEPROM acknowldgs rcipt of th first data word, th microcontrollr can transmit up to 27 mor data words. Th EEPROM will rspond with a 0 aftr ach data word rcivd. Th microcontrollr must trminat th pag writ squnc with a stop condition (s Figur 9 on pag ). Th data word addrss lowr 7 bits ar intrnally incrmntd following th rcipt of ach data word. Th highr data word addrss bits ar not incrmntd, rtaining th mmory pag row location. Whn th word addrss, intrnally gnratd, rachs th pag boundary, th following byt is placd at th bginning of th sam pag. If mor than 28 data words ar transmittd to th EEPROM, th data word addrss will roll ovr and prvious data will b ovrwrittn. Th addrss roll ovr during writ is from th last byt of th currnt pag to th first byt of th sam pag. ACKNOWLEDGE POLLING: Onc th intrnally-timd writ cycl has startd and th EEPROM inputs ar disabld, acknowldg polling can b initiatd. This involvs snding a start condition followd by th dvic addrss word. Th Rad/Writ bit is rprsntativ of th opration dsird. Only if th intrnal writ cycl has compltd will th EEPROM rspond with a 0, allowing th rad or writ squnc to continu. 9

Rad Oprations Rad oprations ar initiatd th sam way as writ oprations with th xcption that th Rad/Writ slct bit in th dvic addrss word is st to. Thr ar thr rad oprations: currnt addrss rad, random addrss rad and squntial rad. CURRENT ADDRESS READ: Th intrnal data word addrss countr maintains th last addrss accssd during th last rad or writ opration, incrmntd by. This addrss stays valid btwn oprations as long as th chip powr is maintaind. Th addrss roll ovr during rad is from th last byt of th last mmory pag, to th first byt of th first pag. Onc th dvic addrss with th Rad/Writ slct bit st to is clockd in and acknowldgd by th EEPROM, th currnt addrss data word is srially clockd out. Th microcontrollr dos not rspond with an input 0 but dos gnrat a following stop condition (s Figur 0 on pag ). RANDOM READ: A random rad rquirs a dummy byt writ squnc to load in th data word addrss. Onc th dvic addrss word and data word addrss ar clockd in and acknowldgd by th EEPROM, th microcontrollr must gnrat anothr start condition. Th microcontrollr now initiats a currnt addrss rad by snding a dvic addrss with th Rad/Writ slct bit high. Th EEPROM acknowldgs th dvic addrss and srially clocks out th data word. Th microcontrollr dos not rspond with a 0 but dos gnrat a following stop condition (s Figur on pag ). SEQUENTIAL READ: Squntial rads ar initiatd by ithr a currnt addrss rad or a random addrss rad. Aftr th microcontrollr rcivs a data word, it rsponds with an acknowldg. As long as th EEPROM rcivs an acknowldg, it will continu to incrmnt th data word addrss and srially clock out squntial data words. Whn th mmory addrss limit is rachd, th data word addrss will roll ovr and th squntial rad will continu. Th squntial rad opration is trminatd whn th microcontrollr dos not rspond with a 0 but dos gnrat a following stop condition (s Figur 2 on pag 2). Figur 7. Dvic Addrss 0 AT24C52
