Pin Dscription : Th srial data input pin accpts op cods, addrsss and data. In SPI mods (0,0) and (1,1) input data is latchd on th rising dg of th clock input. : Th srial data output pin is usd to transfr data out of th dvic. In SPI mods (0,0) and (1,1) data is shiftd out on th falling dg of th clock. : Th srial clock input pin accpts th clock providd by th host and usd for synchronizing communication btwn host and CT25080/160. : Th chip slct input pin is usd to nabl/disabl th CT25080/160. Whn is high, th output is tri statd (high impdanc) and th dvic is in Standby Mod (unlss an intrnal writ opration is in progrss). Evry communication sssion btwn host and CT25080/160 must b prcdd by a high to low transition and concludd with a low to high transition of th input. WP: Th writ protct input pin will allow all writ oprations to th dvic whn hld high. Whn WP pin is tid low and th WPEN bit in th Status Rgistr (rfr to Status Rgistr dscription, latr in this Data Sht) is st to 1, writing to th Status Rgistr is disabld. HOLD: Th HOLD input pin is usd to paus transmission btwn host and CT25080/160, without having to rtransmit th ntir squnc at a latr tim. To paus, HOLD must b takn low and to rsum it must b takn back high, with th input low during both transitions. Whn not usd for pausing, th HOLD input should b tid to V CC, ithr dirctly or through a rsistor. Functional Dscription Th CT25080/160 dvics support th Srial Priphral Intrfac (SPI) bus protocol, mods (0,0) and (1,1). Th dvic contains an 8 bit instruction rgistr. Th instruction st and associatd op cods ar listd in Tabl 9. Rading data stord in th CT25080/160 is accomplishd by simply providing th RED command and an addrss. Writing to th CT25080/160, in addition to a WRITE command, addrss and data, also rquirs nabling th dvic for writing by first stting crtain bits in a Status Rgistr, as will b xplaind latr. ftr a high to low transition on th input pin, th CT25080/160 will accpt any on of th six instruction op cods listd in Tabl 9 and will ignor all othr possibl 8 bit combinations. Th communication protocol follows th timing from Figur 2. Tabl 9.

Synchronous Data Timing Status Rgistr Th Status Rgistr, as shown in Tabl 10, contains a numbr of status and control bits. Th RDY (Rady) bit indicats whthr th dvic is busy with a writ opration. This bit is automatically st to 1 during an intrnal writ cycl, and rst to 0 whn th dvic is rady to accpt commands. For th host, this bit is rad only. Th WEL (Writ Enabl Latch) bit is st/rst by th WREN/WRDI commands. Whn st to 1, th dvic is in a Writ Enabl stat and whn st to 0, th dvic is in a Writ Disabl stat. Th BP0 and BP1 (Block Protct) bits dtrmin which blocks ar currntly writ protctd. Thy ar st by th usr with th WRSR command and ar non volatil.

WRITE OPERTIONS Th CT25080/160 dvic powrs up into a writ disabl stat. Th dvic contains a Writ Enabl Latch (WEL) which must b st bfor attmpting to writ to th mmory array or to th status rgistr. In addition, th addrss of th mmory location(s) to b writtn must b outsid th protctd ara, as dfind by BP0 and BP1 bits from th status rgistr. Writ Enabl and Writ Disabl Th intrnal Writ Enabl Latch and th corrsponding Status Rgistr WEL bit ar st by snding th WREN instruction to th CT25080/160. Car must b takn to tak th input high aftr th WREN instruction, as othrwis th Writ Enabl Latch will not b proprly st. WREN timing is illustratd in Figur 3. Th WREN instruction must b snt prior to any WRITE or WRSR instruction. Th intrnal writ nabl latch is rst by snding th WRDI instruction as shown in Figur 4.

Byt Writ Onc th WEL bit is st, th usr may xcut a writ squnc, by snding a WRITE instruction, a 16 bit addrss and data as shown in Figur 5. Only 10 significant addrss bits ar usd by th CT25080 and 11 by th CT25160. Th rst ar don t car bits, as shown in Tabl 13. Intrnal programming will start aftr th low to high transition. During an intrnal writ cycl, all commands, xcpt for RDSR (Rad Status Rgistr) will b ignord. Th RDY bit will indicat if th intrnal writ cycl is in progrss (RDY high), or th dvic is rady to accpt commands (RDY low). Pag Writ ftr snding th first data byt to th CT25080/160, th host may continu snding data, up to a total of 32 byts, according to timing shown in Figur 6. ftr ach data byt, th lowr ordr addrss bits ar automatically incrmntd, whil th highr ordr addrss bits (pag addrss) rmain unchangd. If during this procss th nd of pag is xcdd, thn loading will roll ovr to th first byt in th pag, thus possibly ovrwriting prviously loadd data.

Writ Status Rgistr Th Status Rgistr is writtn by snding a WRSR instruction according to timing shown in Figur 7. Only bits 2, 3 and 7 can b writtn using th WRSR command. Writ Protction Th Writ Protct (WP) pin can b usd to protct th Block Protct bits BP0 and BP1 against bing inadvrtntly altrd. Whn WP is low and th WPEN bit is st to 1, writ oprations to th Status Rgistr ar inhibitd. WP going low whil is still low will intrrupt a writ to th status rgistr.

RED OPERTIONS Rad from Mmory rray To rad from mmory, th host snds a RED instruction followd by a 16 bit addrss (s Tabl 13 for th numbr of significant addrss bits). ftr rciving th last addrss bit, th CT25080/160 will rspond by shifting out data on th pin (as shown in Figur 9). Squntially stord data can b rad out by simply continuing to run th clock. Th intrnal addrss pointr is automatically incrmntd to th nxt highr addrss as data is shiftd out. ftr raching th highst mmory addrss, th addrss countr rolls ovr to th lowst mmory addrss, and th rad cycl can b continud indfinitly. Th rad opration is trminatd by taking high. Rad Status Rgistr To rad th status rgistr, th host simply snds a RDSR command. ftr rciving th last bit of th command, th CT25080/160 will shift out th contnts of th status rgistr on th pin (Figur 10). Th status rgistr may b rad at any tim, including during an intrnal writ cycl. Whil th intrnal writ cycl is in progrss, th RDSR command will output th full contnt of th status rgistr (Nw product, Rv. D) or th RDY (Rady) bit only (i.., data out = FFh) for prvious product rvision C (Matur product). For asy dtction of th intrnal writ cycl compltion, both during writing to th mmory array and to th status rgistr, w rcommnd sampling th RDY bit only through th polling routin. ftr dtcting th RDY bit 0, th nxt RDSR instruction will always output th xpctd contnt of th status rgistr. 0 1 2 3 4 5 6 7 8 9 10 20 21 22 23 24 25 26 27 28 29 30 OPCODE BYTE DDRESS* 0 0 0 0 0 0 1 1 N 0 HIGH IMPEDNCE Dashd Lin = mod (1, 1) * Plas chck th Byt ddrss Tabl (Tabl 13) Figur 9.

Hold Opration Th HOLD input can b usd to paus communication btwn host and CT25080/160. To paus, HOLD must b takn low whil is low (Figur 11). During th hold condition th dvic must rmain slctd ( low). During th paus, th data output pin () is tri statd (high impdanc) and transitions ar ignord. To rsum communication, HOLD must b takn high whil is low. Dsign Considrations Th CT25080/160 dvics incorporat Powr On Rst (POR) circuitry which protcts th intrnal logic against powring up in th wrong stat. Th dvic will powr up into Standby mod aftr V CC xcds th POR triggr lvl and will powr down into Rst mod whn V CC drops blow th POR triggr lvl. This bi dirctional POR bhavior protcts th dvic against brown out failur following a tmporary loss of powr. Th CT25080/160 dvic powrs up in a writ disabl stat and in a low powr standby mod. WREN instruction must b issud prior to any writs to th dvic. ftr powr up, th pin must b brought low to ntr a rady stat and rciv an instruction. ftr a succssful byt/pag writ or status rgistr writ, th dvic gos into a writ disabl mod.
