KA2004-BE51A Printheads For Mobile, FET-POS, Debit Card, PDA, ECR 2.7V Print Voltage (B Series) KA2004-BE51A Not only hand-held printers, but card payment terminals (EFT-POS) and compact label printers require less than 8.5V of supply voltage. ROHM’s B Series of thermal printheads, developed using cutting-edge LSI technology, can operate on a single lithium ion battery and contribute to end-product miniaturization. zApplications Mobile printers EFT-POS printers Hand-held printers Debit printers zFeatures 1) The B series brings reduced height of protective resin for IC and enlarged paper pathway for thermal papers. Thanks to ROHM’s latest LSI high integrated mounting technology and it’s ultra slim driver IC. 2) The B series accede the great world class low energy consumption characteristics of GP series. 3) Because the print heads circuits draw 2.7V, the printer can be driven using a single lithium battery. zDimensions (Unit : mm) 117 104 (Effective Print Width) Exposed Conductor Side Insert Direction Connector Rev.A 1/4 KA2004-BE51A Printheads zEquivalent circuit DOT #832 DOT #1 VH L-GND P-GND #7 69 ～ #70 5～ # 64 1～ #19 3～ #1 29～ #6 5～ # 1～ ＃8 32 ＃76 8 ＃704 ＃25 6 ＃19 2 ＃1 28 ＃64 STB7 STB6 STB2 STB1 /AEO2 /AEO1 LATCH REGISTER /LAT CLK DI ＬＡＴＣＨ ＲＥＧＩＳＴＥＲ SHIFT REGISTER DO VDD NC THERMISTOR 30ｋΩ B：3950K TM TM CONNECTOR zPin assignments No. Circuit No. Circuit 1 VH 15 P-GND 2 VH 16 P-GND 3 VH 17 P-GND 4 DO 18 L-GND 5 /LAT 19 /AEO1 6 CLK 20 /AEO2 7 VDD 21 STB4 8 STB1 22 STB5 9 STB2 23 STB6 10 STB3 24 STB7 11 TM 25 DI 12 TM 26 VH 13 P-GND 27 VH 14 P-GND 28 VH Rev.A 2/4 KA2004-BE51A Printheads zTiming chart tw CLK CLK (CLOCK) t setup DI t hold DI DI(DATA IN) "High":BLACK "LOW" :WHITE td DO DO (DATA OUT) "High":BLACK "LOW" :WHITE t setup LAT min.10 μ∗sec Min.10µs (Max. tdo)* t hold LAT /LAT (LATCH) "High": HOLD "LOW" : THROUGH tw LAT t setup STB STB (STROBE) /AEO (AREA ENABLE OUT) t do t do DRIVER OUT *If delay time for Driver Out can not be secured enough, there is a possibility that VH would fluctuate greatly.
