The display RAM data that addressed Display Start Address register output to common driver start line. The actual common start line of LCD panel depend on Display Start Common register and SHIFT bit of Display Control register. The register are preset every timing of FLM signal variation in the display line counter. The line counter counts up being synchronized with LP input and generates line addresses which read out sequentially 288 bits data from display RAM to LCD drive circuit. 7.5 Addressing of Display RAM The EM65100 has built-in bit mapped display RAM. The display RAM consists of 208 bits in the X-direction and 69 bits in the Y-direction. In the gradation display mode, the EM65100 provides segment driver output for 4-gradation display using 2 bits. When connected to an STN LCD panel, the EM65100 can display 101*69 pixels with 4-gradation display. The address area in the X-direction depends on the access bus size. When use 8-bits bus size, can access 00H to 19H address. In the X-direction, X Address register use to access; and in the Y-direction, Y Address register use to access. Do not specify any address outside the effective address area in each access mode because it is not permitted. * This specification is subject to be changed without notice. 2005/3/8 (V0.6) 18 EM65100 69 COM/ 101 SEG 4 Gray Level STN LCD Driver In Gradation Display Mode (MON=”0”) 8-bits bus size access X-address 0H 1H ----------------------------------------------------------------- 18H 19H 0H 8bit 8bit 8bit 8bit ---------------- Y-address 44H 8bit 8bit 8bit 8bit The addresses, X Address and Y Address are possible to be set up so that they can increment automatically with the address control register. The increment is made every time display RAM is read or written from MPU. In the Y-direction, 208 bits of data are read out to the display data latch circuit by internal operation when the LP rises in a one-line cycle. They are output from the display data latch circuit when the LP fails. When FLM signals being output in one frame cycle are at “H”, the values in the display starting line register are preset in the line counter and the line counter counts up at the falling of LP signals. The display line address counter is synchronized with each timing signal of the LCD system to operate and is independent of address counters X and Y. 7.6 Display RAM Data and LCD (only monochrome mode) One bit of display RAM data corresponds to one dot of LCD. Normal display and reverse display by REV register are set up as follows. Normal display (REV=0): RAM data = “0” not lighted RAM data = “1” lighted Reverse display (REV=1): RAM data = “0” lighted RAM data = “1” not lighted 7.7 Segment Display Output Order/Reverse Set up The order of display output, SEG0 to SEG100 can be reversed. If REF control bit set to “1”, display by reversing access to display RAM from MPU by using REF register, lessen the limitation in placing IC when assembling an LCD panel module. * This specification is subject to be changed without notice. 2005/3/8 (V0.6) 19 EM65100 69 COM/ 101 SEG 4 Gray Level STN LCD Driver 7.8 Relationship between Display RAM and Address The Display RAM block diagram shows in the figure below: Internal Data Bus Segm ent data Read Data Y-Address (00H~44H) Effective Y address AY Register Display RAM LA Register Bit order reverse W rite Data SEGMENT Output I/F Data conversion is depend on MON,,REF Display start address Data Conversion Counter Bit-order reverse W rite:depend on REF Read:depend on REF X-Address (00H~19H) Effective X address Address conversion circuit AX Register Address conversion is depend on M ON,REF setting Valid m aximum is depend on M ON setting MPU I/F Figure 10.

For instance when REF and AXI are both “1”, AX register is added one, but effective X address seems decrement because of address conversion. The effective Y address use AY register values as it is. * This specification is subject to be changed without notice. 2005/3/8 (V0.6) 20 EM65100 69 COM/ 101 SEG 4 Gray Level STN LCD Driver (1) Monochrome mode, 8-bits Access mode X Address Y Address REF=1 X =0CH X =0BH ----- X = 00H REF=0 X = 00H X = 01H ----- X = 0CH Common Output Note 1 D6 D7 D4 D5 D2 D3 D0 D1 D6 D7 D4 D5 D2 D3 D0 D1 ----- D6 D7 D4 D5 D2 D3 D0 D1 Note 2 D0 D1 D2 D3 D4 D5 D6 D7 D0 D1 D2 D3 D4 D5 D6 D7 ----- D0 D1 D2 D3 D4 D5 D6 D7 Display Start Line 00H COM0 01H 01H COM1 02H 02H COM2 03H 03H 04H 04H 05H 05H 06H 06H COM6 07H 07H COM7 08H COM8 ----- 08H Line Address 00H COM3 COM4 COM5 09H 09H COM9 0AH 0AH COM10 0BH 0BH COM11 0CH 0CH COM12 0DH 0DH COM13 0EH 0EH COM14 0FH 0FH COM15 ------------ ------------ ------------ ------------ ------------ ----- 3CH 3CH COM61 3DH 3DH COM62 3EH 3EH COM63 3FH 3FH COM64 ----- 40H 40H COM65 41H 41H COM66 42H 42H COM67 43H 43H COMA 44H 44H COMB SEG100 SEG99 SEG6 SEG5 SEG4 SEG3 SEG2 SEG1 SEG0 Segment Output ----- Note1: REF=1 Note2: REF=0 * This specification is subject to be changed without notice. 2005/3/8 (V0.6) 21 EM65100 69 COM/ 101 SEG 4 Gray Level STN LCD Driver (2)Gradation mode, 8 bits access mode, REF =0 X Address Common Output Y Address X = 00H X = 01H ----- X = 19H D0 D1 D2 D3 D4 D5 D6 D7 D0 D1 D2 D3 D4 D5 D6 D7 ----- D0 D1 D2 D3 D4 D5 D6 D7 00H Display Start Line 00H ----- 01H COM0 COM1 02H 02H COM2 03H 03H 04H 04H 05H 05H 06H 06H COM6 07H 07H COM7 08H 08H COM8 09H 09H COM9 0AH 0AH COM10 0BH 0BH COM11 0CH 0CH COM12 0DH 0DH COM13 0EH 0EH COM14 0FH 0FH COM15 COM3 COM4 COM5 ------------ ------------ ------------ ------------ ------------ ----- Line Address 01H 3CH 3CH COM61 3DH 3DH COM62 3EH 3EH COM63 3FH 3FH COM64 ----- 40H 40H COM65 41H 41H COM66 42H 42H COM67 43H 43H COMA 44H 44H COMB SEG100 SEG99 SEG6 SEG5 SEG4 SEG3 SEG2 SEG1 SEG0 Output Segment * This specification is subject to be changed without notice. 2005/3/8 (V0.6) 22 EM65100 69 COM/ 101 SEG 4 Gray Level STN LCD Driver 7.9 Display Data Structure and Gradation Control For the purpose of gradation control, one pixel requires multiple bits of display RAM. The EM65100 has 2-bit data per output to achieve the gradation display. The EM65100 is connected to an STN LCD panel. It can display 101*69 pixels with 4-gray level. In this case, since the gradation display data is processed by a single access to the memory, the data can be rewritten fast and naturally.

Select either of the two modes using the gradation display mode register. PWM = “0”: Selects the variable display mode using 4 gradation selected from 16 gradation. PWM = “1”: Selects the fixed display mode using specific 4 gradation. To select the best gradation level suited to the LCD panel, use the gradation palette register among the 16-level gradation palettes in the gradation variable display mode. The segment driver output is set up by the selected 4-levels of gradation palettes. Each register consists of a 2-bit register, selecting 4-gradations from the pattern for 16-gradations.

It can select external input (CK) or internal oscillation. Symbol Description The LP is latch clock signal. LP(internal) At the rising edge, count the display line counter. At the falling edge output the LCD drive signal. The signal for LCD display synchronous signals (first line maker). FLM(internal) When FLM is set to “H”, the display start-line address is preset. In the display line counter M(internal) The signal for alternated signals of LCD drive output. 7.12 Signal Generation to Display Line Counter, and Display Data Latching Circuit Both the clock to the line counter and clock to display data latching circuit from the display clock (internal LP) are generated. Synchronized with the display clock (internal LP), the line addresses of Display RAM are generated and 208-bits display data are latched to display data latching circuit to output to the LCD drive circuit (Segment outputs). Read-out of the display data to the LCD drive circuit is completely independent of MPU. Therefore, MPU that has no relationship the read-out operation of the display data can access. 7.13 Generation of the Alternated Signal (internal M) and the Synchronous Signal (internal FLM) LCD alternated signal (internal M) and synchronous signal (internal FLM) are generated by the display clock (internal LP). The FLM generates alternated drive waveform to the LCD drive circuit. Normally, the FLM generates alternated drive waveform every frame (M-signal level is reversed every one frame). However, by setting up data (n-1) in an n-line reverse register and n-line alternated control bit (NLIN) at “1”, n-line reverse waveform is generated. 7.14 Display Data Latching Circuit Display data latching Circuit temporally latches display data that is output display data to LCD driver circuit from display RAM every one common period. Normal display/reverse display, display ON/OFF, and display all on functions are operated by controlling data in display data latch. Therefore, no data within display RAM changes. * This specification is subject to be changed without notice. 2005/3/8 (V0.6) 26 EM65100 69 COM/ 101 SEG 4 Gray Level STN LCD Driver 7.15 Output Timing of LCD Driver Display timing at Normal mode (not reverse mode), 1/69 DUTY, and on monochrome mode. 68 69 1 2 3 69 1 2 3 69 1 LP(internal) FLM(internal) M(internal) COM0 COM1 SEG0 SEG1 7.16 LCD Drive Circuit This drive circuit generates four levels LCD drive voltage.

The COMA and COMB outputs be not influenced by partial setting. Mainly use for display. The common drive circuit that has shift register sequentially outputs common scan signals. 7.17 Oscillating Circuit The EM65100 has the CR oscillator. The output from this oscillator is used as the timing signal source of the display and the boosting clock to the booster. This can use only in the master operation mode. * This specification is subject to be changed without notice. 2005/3/8 (V0.6) 27 EM65100 69 COM/ 101 SEG 4 Gray Level STN LCD Driver When in the master operation mode and external clock is used, feed the clock to CK pin. The duty cycle of the external clock must be 50%. The resistance ratio of CR oscillator is programmable. If change this ratio, also change frame frequency for display. 7.18 Power Supply Circuit This circuit supplies voltages necessary to drive a LCD. The circuit consists of booster and voltage converter. Boosted voltage from the booster is fed to the voltage converter that converts this input voltage into V0, V1, V2, V3 and V4 that are used to drive the LCD. This internal power supply should not be used to drive a large LCD panel containing many pixels. Otherwise, display quality will degrade considerably. Instead, use an external power supply. When using the external power supply, turn off the internal power supply (AMPON, DCON=”00”), disconnect pins CAP1+, CAP1-, CAP2+, CAP2-, CAP3+, Vcc, Vci, VREF Then, feed external LCD drive voltages to pins V0, V1, V2, V3 and V4. The power circuit can be control by power circuit related register. So partial function of built-in power circuit can use with external power supply.

Vcc=12V Vcc=9 V Vci=3V Vci=3V VSS=0V VSS=0V 3 times boostng 4 times boostng 7.20 Electronic volume The voltage conversion circuit has built-in an electronic volume, which allows the LCD drive voltage level V0 to be controlled with DV register setting and allows the tone of LCD to be controlled. The DV registers are 7-bits, so can select 128 voltage values for the LCD drive voltage V0. 7.21 Voltage Regulator The EM65100 has built-in reference voltage regulator, which generate the voltage amplified by input voltage from VREF pin. The generated voltage is output at the VREG (internal). Even if the boosted voltage level fluctuates, VREG (internal) remains stable so far as Vcc is higher than VREG Stable power supply can be obtained using this constant voltage, even if the load fluctuates. The EM65100 uses the generated VREG level for the reference level of the electronic volume to generate LCD drive voltage. 7.22 LCD Drive Voltage Generation Circuit The voltage converter contains the voltage generation circuit. The LCD drive voltages other than V0, that is, V1, V2, V3 and V4 are obtained by dividing V0 through a resistor network. The LCD drive voltage from EM65100 is biased at 1/5, 1/6, 1/7, 1/8 or 1/9. When using the internal power supply, connect a stabilizing capacitor C2 to each of pins V0 to V4. The capacitance of C2 should be determined while observing the LCD panel to be used. When using the external power supply, apply external LCD drive voltages to V0, V1, V2, V3, V4, disconnect pins CAP1+, CAP1-, CAP2+, CAP2-, CAP3+, Vcc, Vci, and VREF. When using only the voltage conversion circuit, turn off the internal booster circuit, disconnect pins CAP1+, CAP1-, CAP2+, CAP2-, CAP3+, and Vci.

The detail is as follows. ( i )When using as external power supply ‧ Procedure for Power ON (1) Logic system (VDD) power ON, make reset operation. (2) Supply external LCD drive voltage to corresponding pins (V0, V1, V2, V3 and V4) ‧ Procedure for Power OFF (1) Set HALT register to “1” or make reset operation. (2) Cut off external LCD drive voltage. (3) Logic system(VDD) power OFF. Note: connect the serial resistor (50 to 100Ω) or fuse to the LCD drive power V0 or Vcc(when only use internal voltage conversion circuit) of the system as a current limiter. Moreover, set up the suitable value of the resistor in consideration of LCD display grade. ( ii )When using the built-in power supply ‧ Procedure for Power ON (1) Logic system (VDD) power ON (2) Booster circuit system (Vci) power ON (3) Make reset operation, booster and voltage conversion circuit enable. If VDD and Vci voltages aren’t same potential, power on logic system (VDD) first. ‧ Procedure for Power OFF (1) Set HALT register to “1” or make reset operation. (2) Booster circuit system (Vci) power ON (3) Logic system (VDD) power OFF. If VDD and Vci are not same potential, cut off Vci first. After Vci, Vcc, V0, V1, V2, V3 and V4 voltages are below LCD ON voltage (threshold voltage for Liquid crystal turn on), power off logic system (VDD).

When the SHIFT bit is “0”, the common position change in the forward direction. When “1” they change reverse direction. When “0” is selected as the values for LA6 to LA0 in the Display Starting Line Set command, the MY number corresponding to the display starting position is “0”. The MY numbers are sequentially shifted backward when display occurs. In any case, the relations of COMA = MY67 and COMB = MY68 do not change. When non-zero is selected for the display starting line: The relationship between the COM pins and the addresses in the vertical direction on the display RAM, MY changes on an 15 dots basis according to the information in the LCD Duty Set command and Display Starting Common Position Set command. The common positions change in the forward when the SHIFT bit is “0”, and change in the reverse direction when the SHIFT bit is “1”. If non-zero is selected for the values for LA6 to LA0 by the Display Starting Line set command. the MY number corresponding to the display starting position shifts by the set value. The MY number shifts backward when display occurs. If it exceeds 66, it returns to 0, and the shifts sequentially. In any case, the relations of COMA = MY67 and COMB = MY68 do not change. * This specification is subject to be changed without notice. 2005/3/8 (V0.6) 61 EM65100 69 COM/ 101 SEG 4 Gray Level STN LCD Driver 10.
