Single-Chip, Jinglong-Low Power 65COM by 132SEG Passive Matrix LCDController-Driver 

INTRODUCTION 

J1880x is an advanced high-voltagemixed-signalCMOS IC,especially designed forthe display needs ofJinglong-low powerhand-held devices. 

Thischip employsJinglongChip’suniqueDCC (Direct CapacitorCoupling)driver architectureto achieve nearcrosstalk freeimages. 

In addition to low powercolumn and rowdrivers, the IC containsallnecessarycircuits forhigh-V LCD power supply,bias voltagegeneration, timing generation and graphicsdatamemory. 

Advanced circuit design techniquesareemployed to minimize external component counts and reduceconnectorsize while achieving extremely low powerconsumption.

PIN DESCRIPTION 

Name  Type  Pins  Description  

MAIN POWERSUPPLY  

VDD VDD2 VDD3  PWR  3 4 2  VDD supplies for Display Data RAM and digital logic, VDD2 supplies for VLCD and VD generator, VDD3 supplies for VBIAS and other analog circuits. VDD2/VDD3 should be connected to the same power source. But VDDcan be connected to a source voltage no higher thanVDD2/VDD3. Please maintain the followingrelationship: VDD+1.3V “ VDD2/3“ VDD ITO trace resistance needs to be minimized forVDD2/VDD3.  

VSS VSS2  GND  2 4  Ground. Connect VSS and VSS2 to the shared GND pin. In COG applications, minimize the ITO resistance for both VSS andVSS2.  

LCDPOWER SUPPLY&VOLTAGE CONTROL  

VB0+ VB0– VB1+ VB1–  PWR  2 2 4 2  LCD Bias Voltages. These are the voltage sources to provideSEG driving currents. These voltages are generated internally. Connect capacitors of CBX value between VBX+ and VBX–. In COG application,the resistanceof these ITO tracesdirectly affects the SEG driving strength of the resulting LCD module. Minimize thesetrace resistance is critical in achieving high qualityimage.  

VLCDIN VLCDOUT  PWR  2 2  Main LCD Power Supply.When VLCD is used, connect thesepins together. By-pass capacitor CL is optional. It can be connected between VLCD and VSS.When CL is used, keep the ITO trace resistance around 70~100..  


NOTE 

. Recommended capacitor values: CB: 2.2μF/5V or100~250x(LCD loadcapacitance). 

CL: 330nF/25V is appropriate for mostapplications.

Name  Type  Pins  Description  

MISC.PINS  

VDDX  2  Auxiliary VDD. This pin is connected to the main VDD bus within the IC. It’s provided to facilitate chip configurationsin COG application. There’s no need to connect VDDX to main VDD externally and it should NOT be used to provide VDD power to the chip.  

VSSX  2  Auxiliary Vss. These pins are connected to the main Vss bus within the IC,to facilitate chip configurations in COGapplication. There’s no need to connect VssX to main Vss externally and theyshould NOT be used to provide Vss power to the chip.  

TST4  I  1  Test control. There’s an on-chip pull-up resistor for TST4. Leave itopen during normaluse.  

TST2  I/O  1  Test I/O pins. Leave these pins open during normaluse.  

Dummy  11  Dummy pins are NOT connected inside theIC.  


Note: Several controlregisters will specify “0 based index” forCOM and SEG electrodes. Inthose situations,COMx orSEGx willcorrespond to indexx-1,and the valuerange forthose indexregisterwillbe 0~63 forCOMand 0~131 forSEG.
