Description
The EM6124 is a low power CMOS LCD controller and driver. The 8, 16, 20 and 24 way multiplex are digitally programmable by the command byte. One additional line can be added for Icons or Inverted Video by programming 9, 17, 21 or 25 way multiplex. The display refresh is handled on chip by an internal RC oscillator via one selectable 25 x 116 RAM which holds the LCD content driven by the driver. LCD pixels (or segments) are addressed on a one to one basis with the 25 x 116 bit RAM (a set bit corresponds to an activated LCD pixel). The EM6124 has very low dynamic current consumption, typically 70 A at VDD = 2 V, VLCD = 7 V making it particularly attractive for portable and battery powered products. The wide operating range on supply voltages and temperature offers much application flexibility. The LCD voltage, bias generation and frame frequency are generated on chip. The clock signal can be used to shift and to latch the data into the RAM.

1 Bit Interface Description
This 1 bit interface is very simple to use. There are three modes to load data into the EM6124.
Init.bit 8-9: Mux mode bits. The multiplex ratio is selected by these two bits. Table 8 shows the corresponding values. Init.bit 10-11: VLCD temperature coefficient is selected by these two bits. Table 11 shows the corresponding values. Init.bit 12: Checker bit gives the possibility to force all outputs segments in checked form (see Fig. 10 and Fig. 18.14). Init.bit 13: Inverse Checker bit gives the possibility to force all outputs segments in inverse checked form (see Fig. 10 and Fig. 18.15). Init.bit 14: Col bit configures the EM6124 on row and column driver or column driver only. In this mode the frame frequency must be external. Init.bit 15: Row inversion, possibility to inverse the order of the row outputs (see Table 10 and Fig. 18.12). Init.bit 16: M/LSB, possibility to inverse the order loading for RAM data (see Fig. 4). Init.bit 17: Video bit, possibility to inverse the content of the RAM. All the 0L pass to 1L and all the 1L pass to 0L (see Fig. 18.11). Init.bit 18-23: VLCD 64 steps programmation bits. See Fig. 8. Bit 18 (step 1) for MSB and bit 23 (step 6) for LSB. Init.bit 24: Icon bit adds one line more to the selected mux mode ratio for icon segments outputs. Init.bit 25: Sleep 2. Set all outputs at VSS. Init.bit 26-31: Must be setted to 0L.
Command byte only mode
To validate this mode, 8 bits must be shifted with bit 3 to bit 7 setted to 1L. This mode is used for blank, set or sleep mode functions.
Command byte and initialization mode
To validate this mode, 32 bits must be shifted with bit 0 and bit 1 setted to 1L. Bit 2 (sleep) can be active or inactive. Bit 3 to bit 7 (RAM address) can be in any state but it is important that they are not all simultaneously setted to 1L, otherwise the chip will be in command byte only mode.
Command byte and display information mode
To validate this mode, 128 bits must be shifted, eight first bits are for command byte, all the other are RAM data depending of col bit mode and multiplex ratio. There are also x bits don't care in each loading depending on the programmation of the chip (see Fig. 4 for more details). In each RAM's data loading, the command byte has to be introduced for the RAM address. Before loading any data into the RAM the chip has to be initialized.
Command Byte
Commmand Bits 0 to 7 0 Blank 1 Set 2 Sleep 3 4 5 6 RAM address 7
Reset 1
Power-up: Must be followed by a RESET cycle. After the reset 1 pulse the LCD controller driver is set to the following status: - All outputs at VSS - Blank & Set (cmdbits 0,1) = 0L - Sleep mode (cmdbit 2) = 0L - RAM address (cmdbits 3 to 7) = 0L - Multiplex ratio (init.bits 8, 9) = 0L - Temperature coefficient (init.bits 10,11) = 0L - Checker & Inv.Checker (init.bits 12, 13) = 0L - Col Mode (init.bit 14) = 1L - Inv. Row (init.bit 15) = 0L - M/LSB (init.bit 16) = 1L - Video (init.bit 17) = 1L - VLCD step (init.bits 18 to 23) = 0L - Icon (init.bit 24) = 0L - Sleep 2 (init.bit 25) = 1L - The content of the RAM remains unchanged An initialization should take place after reset (32 bits sent).
Table 6
Cmdbit 0: Blank bit forces all column outputs off. Cmdbit 1: Set bit forces all column output on. Note: If bit 0 and bit 1 are both to 1L, the chip will be in initialization mode. See remarks below. Cmdbit 2: Sleep mode bit, stops the voltage booster and the internal oscillator, active bit col forces all outputs to VSS. Cmdbits 3-7: RAM address bits. See table 6. If Cmdbits 3-7 are set to 1L, EM6124 is in Cmd byte only mode.

Typical VLCD Programming Checker and Checker Inverse
A fast check display can be easily created setting initialization bits 12 and 13 (called "Checker" and "Inv. Checker"). The display is completely checked with only 2 initialization sequences, one "Checker" and one "Inv. Checker". For Checker, the pattern fills the display with alternately ON and OFF pixels as shown in Fig. 10. For Inv. Checker, everything is inverted (see Fig.18.14 and 18.15).
Pattern of Checker Mode
Fig. 10 Internally Generated VLCD versus Temperature Fig. 8 Temperature Control
Due to the temperature dependency of liquid cristals viscosity the LCD controlling voltage VLCD must be increased for lower temperatures to maintain optimal contrast. The EM6124 is available with 4 different temperature coefficients (see Fig. 9). The coefficient is selected by 2 bits in the initialization code TC bits 10 and 11. Table 11 shows the typical values of the different temperature coefficients. They are proportional to the programmed VLCD.

Functional Description
Supply Voltage VDD1, VDD2, VHV, VLCD, VSS
The voltage between VDD1 and VSS is the supply voltage for the logic and the interface. The voltage between VDD2 and VSS is the supply voltage for the analogic. VDD1 and VDD2 must be the same voltage and, in order to guarantee the best functioning, VDD1 and VDD2 have to be separately connected to the PCB (see Fig. 19). The voltage VLCD is internally generated for the supply voltage of the LCD and is used for the generation of the internal LCD bias level. An external capacitor of 1 F must be connected between VLCD and VSS. Table 15 shows the relationship between V1, V2, V3, V4 for a programmed multiplex rate. Note that VLCD > V1 > V2 > V3 > VSS for the EM6124 8 mux programmed, and for the EM6124 16, 20, 24 mux programmed VLCD > V1 > V2 > V3 > V4 > VSS. The voltage between VHV and VSS is the supply voltage for high voltage part of the EM6124. An external VLCD may also be used by connecting a power supply and programming a lower VLCD voltage during initialization. new loading of data. This reset 2 does not change the content of the RAM neither the content of the command and the initialization bits. To avoid trouble in case of software interrupt of the MPU during data loading, this function can be used.
Power-Up
On power up the data in the shift registers, the display RAM, the sequencer driving the 8/16/20/24 rows and the 121 bit display latches are undefined.
CLK Input
The clock input is used to clock the DI serial data into the EM6124.
FR Input / Output
The frame frequency is realized by an internal oscillator with a typical value of 75 Hz. The internal row frequency changes with the number of rows ( Frow = 75 x n, where n = 8, 16, 20, 24). When bit 14 (Col) is inactive (active low), the frame frequency is given by the internal oscillator. This frequency can be measured on the I/O FR. When bit 14 (Col) is active (active low), the frame frequency is external then the frequency is given directly by the FR input to the row and column driver (see Fig. 16 and 17 for more details concerning the frame frequency).
Data Input
The data input pin, DI, is used to load serial data into the EM6124. The normal serial data word length is128 bits. 32 and 8 bits are also available in a special mode (see 1 Bit Interface Description). The command byte is loaded first and then the segment data bits (see Fig. 4).
Driver Outputs S1 to S116
There are 121 LCD driver outputs on the EM6124. The output assignments depend on the chosen mux mode ratio (init. bits 8, 9) and the Col function (init. bit 14). When init. bit 14 (Col) is active, all 116 outputs function as column drivers. Table "Output Row Assignments" and Fig. 4 describe exactly the correspondent data to the output of the chip. There is one to one relationship between the display RAM and the LCD driver outputs. Each pixel (segment) driven by the EM6124 on the LCD has a display RAM bit which corresponds to it. Setting the bit turns the pixel "on" and Clearing it turns "off".
For chip-on-glass better performances can be obtained by covering the backside of the chip.
RES1 Input
Reset is accomplished by applying an external RES1 pulse (active low). When reset occurs within the specified time, all internal register are reset however the content of the RAM is still unchanged. The state after reset is described on page 4.
RES2 Input
Reset is accomplished by applying an external RES2 pulse (active low). When reset occurs within the specified time, the internal counter for serial interface is reset. The counter of the serial interface for data inputs is ready for a
