2.1
Circuit description
Supplies voltages and grounds
VDD2 is supply voltages to the internal voltage generator (see below). If the internal voltage generator is not used, this should be connected to VDD1 pad. VDD1 supplies the rest of the IC. VDD1 supply voltage could be different form VDD2.
2.2
Internal supply voltage generator
The IC has a fully integrated (no external capacitors required) charge pump for the Liquid Crystal Display supply voltage generation. The multiplying factor can be programmed to be: Auto, X6, X5, X4, X3, X2, using the 'set CP Multiplication' Command. If Auto is set, the multiplying factor is automatically selected to have the lowest current consumption in every condition. This make possible to have an input voltage that changes over time and a constant VLCD voltage. The output voltage (VLCDOUT) is tightly controlled through the VLCDSENSE pad. For this voltage, eight different temperature coefficients (TC, rate of change with temperature) can be programmed using the bits TC1 and TC0 and T2,T1 & T0. This will ensure no contrast degradation over the LCD operating range. Using the internal charge pump, the VLCDIN and VLCDOUT pads must be connected together. An external supply could be connected to VLCDIN to supply the LCD without using the internal generator. In such event the VLDCOUT and VLCDSENSE must be connected to GND and the internal voltage generator must be programmed to zero (PRS = [0;0], Vop = 0 - Reset condition).
2.3
Oscillator
A fully integrated oscillator (requires no external components) is present to provide the clock for the Display System. When used the OSC pad must be connected to VDD1 pad. An external oscillator could be used and fed into the OSC pin. An oscillator out is provided on the OSCOUT Pad to cascade two or more drivers
2.4
Bias levels
To properly drive the LCD, six (Including VLCD and VSS) different voltage (Bias) levels are generated. The ratios among these levels and VLCD, should be selected according to the MUX ratio (m). They are established to be (Fig. 4):
n+3 n+2 21V LCD, ------------ V LCD , ------------ V LCD , ------------ V LCD , ------------ V LCD ,V SS n+4 n+4 n+4 n+4

The STE2002 provides three bits (BS0, BS1, BS2) for programming the desired Bias Ratio as shown below: Table 2. Bias ratio programming

LCD voltage generation
The LCD Voltage at reference temperature (To = 27C) can be set using the VOP register content according to the following formula: VLCD(T=To) = VLCDo = (Ai+VOP * B) with the following values: Table 4. LCD voltage values
Value 2.95 6.83 10.71 0.0303 27 Unit V V V V C Note PRS = [0;0] PRS = [0;1] PRS = [1;0]
(i=0,1,2)
Symbol Ao A1 A2 B To
Note that the three PRS values produce three adjacent ranges for VLCD. If the VOP register and PRS bits are set to zero the internal voltage generator is switched off. The proper value for the VLCD is a function of the Liquid Crystal Threshold Voltage (Vth) and of the Multiplexing Rate. A general expression for this is: 1+ m V LCD = -------------------------------------- V th 1 1 - -------- 2 m For MUX Rate m = 65 the ideal VLCD is: VLCD(to) = 6.85 * Vth then: ( 6.85 V th - A i ) V op = -------------------------------------------0.03

Temperature coefficient
As the viscosity, and therefore the contrast, of the LCD are subject to change with temperature, there's the need to vary the LCD Voltage with temperature. The STE2002 provides the possibility to change the VLCD in a linear fashion against temperature with eight different Temperature Coefficient selectable through the T2, T1 and T0 bits. Only four of them are available with basic instruction set (TC1 & TC0 Bits). Table 5.

Display data RAM
The STE2002, provides an 104X128 bits Static RAM to store Display data. This is organized into 13 (Bank0 to Bank12) banks with 128 Bytes. One of these banks (128 bits wide) can be used for Icons. RAM access is accomplished in either one of the Bus Interfaces provided (see below). Allowed addresses are X0 to X127 (Horizontal) and Y0 to Y12 (Vertical). When writing to RAM, four addressing mode are provided: * Normal Horizontal (MX=0 and V=0), having the column with address X= 0 located on the left of the memory map. The X pointer is increased after each byte written. After the last column address (X=X-Carriage), Y address pointer is set to jump to the following bank and X restarts from X=0. (Fig. 6) * Normal Vertical (MX=0 and V=1), having the column with address X= 0 located on the left of the memory map. The Y pointer is increased after each byte written. After the last Y bank address (Y=Y-Carriage), X address pointer is set to jump to next column and Y restarts from Y=0 (Fig. 7). * Mirrored Horizontal (MX=1 and V=0), having the column with address X= 0 located on the right of the memory map. The X pointer is increased after each byte written. After the last column address (X=X-Carriage), Y address pointer is set to jump to the next bank and X restarts from X=0 (fig. 8). * Mirrored Vertical (MX=1 and V=1), having the column with address X= 0 located on the right of the memory map. The Y pointer is increased after each byte written. After the last Y bank address (Y=Y-Carriage), the X pointer is set to jump to next column and Y restarts from Y=0 (fig. 9). After the last allowed address (X;Y)=(X-Carriage; Y-Carriage), the address pointers always jump to the cell with address (X;Y) = (0;0) (Fi. 10, 11, 12 & 13). Data bytes in the memory could have the MSB either on top (D0 = 0, Fig.14) or on the bottom (D0=1, Fig. 15). The STE2002 provides also means to alter the normal output addressing. A mirroring of the Display along the X axis is enabled setting to a logic one MY bit.This function doesn't affect the content of the memory RAM. It is only related to the visualization process. When ICON MODE=1 the Icon Row is not mirrored with MY and is not scrolled. When ICON Mode=0 the Icon Row is like the other graphic lines and is mirrored and scrolled. Four are the multiplex ratio available when the partial display mode is disabled (MUX 33, MUX 49, MUX 65 and MUX 81). Only a subset of writable rows are output on Row drivers. When Y-CarriageMUX/8 lines only 33, 49, 65 or 81 lines are visualized but it is possible to select which lines of DDRAM are connected on the output drivers. The DDRAM rows to visualized can be selected in the 0-Y-Carriage*8 range using the scrolling function.

STE2002
Display data RAM When Y-Carriage>MUX lines, the icon row is moved in DDRAM to the first row of the YCARRIAGE Return BANK even if it is always connected on the same output Driver. When MY=0, the icon Row is output on R80 in mux 81 mode, on R72 in MUX 65, on R64 in MUX49 and on R56 in MUX 33. When MY=1, and ICON MODE=1, the icon Row is output on R80 in mux 81 mode, on R72 in MUX 65, on R64 in MUX49 and on R56 in MUX 33. When MY=1, and ICON MODE=0, the icon Row is output on R0 whatever is the MUX Rate. When ICON MODE =1, the Memory ICON Row content is output on ICON Pad. If Not Used ICON Pad must be left floating.

Instruction set

Instruction set
Two different instructions formats are provided: - With D/C set to LOW commands are sent to the Control circuitry. - With D/C set to HIGH the Data RAM is addressed. Two different instruction set are embedded: the STE2001-like instruction set and the extended instruction set. To select the STE2001-like instruction set the EXT pad has to be connected to a logic LOW (connect to VSS). To select the extended instruction the EXT pad has to be connected to a logic HIGH (connect to VDD1). The instructions have the syntax summarized in Table 10, (basic-set) and Table 11 (extended set).
4.1
Reset (RES)
At power-on, all internal registers are configured with the default value. The RAM content is not defined. A Reset pulse on RES pad (active low) re-initialize the internal registers content (see Table 10, Table 11, Table 12). Applying a reset pulse, every on-going communication with the host controller is interrupted. After the power-on, the Software Reset instruction can be used to re-load the reset configuration into the internal registers The default configurations is: . - Horizontal addressing (V = 0) - Normal instruction set (H[1:0] = 0) - Normal display (MX = MY = 0) - Display blank (E = D = 0) - Address counter X[6: 0] = 0 and Y[4: 0] = 0 - Temperature coefficient (TC[1: 0] = 0) - Bias system (BS[2: 0] = 0) - Multiplexing Ratio (M[1:0]=0) - Frame Rate (FR[1:0]="75Hz") - Power Down (PD = 1) - Dual Partial Display Disabled (PE=0) - VOP=0
A MEMORY BLANK instruction can be executed to clear the RAM content.
4.2
Power down (PD = 1)
When at Power Down, all LCD outputs are kept at VSS (display off). Bias generator and VLCD generator are OFF (VLCDOUT output is discharged to VSS, and then is possible to disconnect VLCDOUT). The internal Oscillator is in off state. An external clock can be provided. The RAM contents is not cleared.

4.3
Memory blanking procedure
This instruction allows to fill the memory with "blank" patterns, in order to delete patterns randomly generated in memory when starting up the device. This instruction substitutes (128X13) single "write" instructions. It is possible to program "Memory Blanking Procedure" only under the following conditions: - PD bit =0
The end of the procedure will be notified on the BSY_FLG pad going HIGH (while LOW the procedure is running). Any instruction programmed with BSY_FLG LOW will be ignored that is, no instruction can be programmed for a period equivalent to 128X13 internal write cycles (128X13X1/fclock). The start of Memory blanking procedure will be between one and two fclock cycles from the last active edge (E rising edge for the parallel interface, last SCLK rising edge for the Serial interface, last SCL rising edge for the I2C interface).
4.4
Checker board procedure
This instruction allows to fill the memory with "checker-board" pattern. It is mainly intended to developers, who can now simply obtain complex module test configuration by means of a single instruction. It is possible to program "Checker Board Procedure" only under the following conditions: - PD bit = 0 The end of the procedure will be notified on the BSY_FLG pad going HIGH, while LOW the procedure is running. Any instruction programmed with BSY_FLG LOW will be ignored, that is, no instruction can be programmed for a period equivalent to 128X13 internal write cycles (128X13X1/fclock). The start of Memory blanking procedure will be between one and two fclock cycles from the last active edge (E rising edge for the parallel interface, last SCLK rising edge for the Serial interface, last SCL rising edge for the I2C interface).
4.5
Scrolling function
The STE2002 can scroll the graphics display in units of raster-rows. The scrolling function is achieved changing the correspondence between the rows of the logical memory map and the output row drivers. The scroll function doesn't affect the data ram content. It is only related to the visualization process. The information output on the drivers is related to the row reading sequence (the 1st row read is output on R0, the 2nd on R1 and so on). Scrolling means reading the matrix starting from a row that is sequentially increased or decreased. After every scrolling command the offset between the memory address and the memory scanning pointer is increased or decreased by one. The offset range changes in accordance with MUX Rate. After 80th/81th scrolling commands in MUX 81 mode, or after the 64th/65th scrolling commands in mux 65 mode, or after 48nd/49rd scrolling command in MUX 49 mode, or after 32nd/33rd scrolling command in MUX 33 mode, the offset between the memory address and the memory scanning pointer is again zero (Cyclic Scrolling). A Reset Scrolling Pointer instruction can be executed to force to zero the offset between the memory address and the memory scanning pointer The Icon Row is not scrolled if ICON MODE =1. If ICON MODE=0 the last row is like a general purpose row and it is scrolled as other rows. If the DIR Bit is set to a logic zero the offset register is increased by one and the raster is scrolled from top down. If the DIR Bit is set to a logic one the offset register is decreased by one and the raster is scrolled from bottom-up.

Dual partial display
If the PE Bit is set to a logic one the dual partial display mode is enabled. Eight partial display modes are available. The offset of the two partial display zones is row by row programmable. The Icon row is accessed last in each partial display frame. Two sets of register for the HV-generator parameters are provided (PRS[1:0], Vop[6:0], BS[2:0], CP[2:0].). This allows switching from normal mode to partial display mode applying one instruction. The HV generator is automatically re configured using the parameters related to the enabled mode. The parameters of the two sets of registers with the same function are located in the same position of the instruction set. The registers related to the normal mode are accessible when normal mode (PE=0) is selected, the others are accessible when the partial display mode is enabled (PE=1). To Setup PRS[1:0], Vop[6:0], BS[2:0], CP[2:0] values the instruction flow proposed in Fig.46 must be followed. To setup Partial Display Sectors Start Address and Partial Display Mode no particular instruction flow has to be followed. Table 8. Dual partial display

Bus interfaces
To provide the widest flexibility and ease of use the STE2002 features three different methods for interfacing the host Controller. To select the desired interface the SEL1 and SEL2 pads need to be connected to a logic LOW (connect to GND) or a logic HIGH (connect to VDD). All the I/O pins of the unused interfaces must be connected to GND. All interfaces are working while the STE2002 is in Power Down Table 9.

5.1
I2C interface
The I2C interface is a fully complying I2C bus specification, selectable to work in both Fast (400kHz Clock) and High Speed Mode (3.4MHz). This bus is intended for communication between different Ics. It consists of two lines: one bidirectional for data signals (SDA) and one for clock signals (SCL). Both the SDA and SCL lines must be connected to a positive supply voltage via an active or passive pull-up. The following protocol has been defined: - Data transfer may be initiated only when the bus is not busy. - During data transfer, the data line must remain stable whenever the clock line is high. Changes in the data line while the clock line is high will be interpreted as control signals. Accordingly, the following bus conditions have been defined: BUS not busy: Both data and clock lines remain High. Start Data Transfer: A change in the state of the data line, from High to Low, while the clock is High, define the START condition. Stop Data Transfer: A Change in the state of the data line, from low to High, while the clock signal is High, defines the STOP condition. Data Valid: The state of the data line represents valid data when after a start condition, the data line is stable for the duration of the High period of the clock signal. The data on the line may be changed during the Low period of the clock signal. There is one clock pulse per bit of data. Each data transfer is initiated with a start condition and terminated with a stop condition. The number of data bytes transferred between the start and the stop conditions is not limited. The information is transmitted byte-wide and each receiver acknowledges with the ninth bit.

STE2002
Bus interfaces By definition, a device that gives out a message is called "transmitter", the receiving device that gets the signals is called "receiver". The device that controls the message is called "master". The devices that are controlled by the master are called "slaves" Acknowledge. Each byte of eight bits is followed by one acknowledge bit. This acknowledge bit is a low level put on the bus by the receiver, whereas the master generates an extra acknowledge related clock pulse. A slave receiver which is addressed must generate an acknowledge after the reception of each byte. Also, a master receiver must generate an acknowledge after the reception of each byte that has been clocked out of the slave transmitter. The device that acknowledges has to pull down the SDA_IN line during the acknowledge clock pulse. Of course, setup and hold time must be taken into account. A master receiver must signal an end-of-data to the slave transmitter by not generating an acknowledge on the last byte that has been clocked out of the slave. In this case, the transmitter must leave the data line High to enable the master to generate the STOP condition. Connecting SDA_IN and SDA_OUT together the SDA line become the standard data line. Having the acknowledge output (SDAOUT) separated from the serial data line is advantageous in Chip-On-Glass (COG) applications. In COG applications where the track resistance from the SDAOUT pad to the system SDA line can be significant, a potential divider is generated by the bus pull-up resistor and the Indium Tin Oxide (ITO) track resistance. It is possible that during the acknowledge cycle the STE2002 will not be able to create a valid logic 0 level. By splitting the SDA input from the output the device could be used in a mode that ignores the acknowledge bit. In COG applications where the acknowledge cycle is required, it is necessary to minimize the track resistance from the SDACK pad to the system SDA line to guarantee a valid LOW level. To be compliant with the I2C-bus Hs-mode specification the STE2002 is able to detect the special sequence "S00001xxx". After this sequence no acknowledge pulse is generated. Since no internal modification are applied to work in Hs-mode, the device is able to work in Hs-mode without detecting the master code. Figure 28. Bit transfer and START,STOP conditions definition

5.1.1
Communication protocol
The STE2002 is an I2C slave. The access to the device is bi-directional since data write and status read are allowed. Four are the device addresses available for the device. All have in common the first 5 bits (01111). The two least significant bit of the slave address are set by connecting the SA0 and SA1 inputs to a logic 0 or to a logic 1. To start the communication between the bus master and the slave LCD driver, the master must initiate a START condition. Following this, the master sends an 8-bit byte, shown in Fig. 30, on the SDA bus line (Most significant bit first). This consists of the 7-bit Device select Code, and the 1-bit Read/Write Designator (R/W). All slaves with the corresponding address acknowledge in parallel, all the others will ignore the I2C-bus transfer.
Writing mode
If the R/W bit is set to logic 0 the STE2002 is set to be a receiver. After the slaves acknowledge one or more command word follows to define the status of the device. A command word is composed by two bytes. The first is a control byte which defines the Co and D/C values, the second is a data byte (fig 31). The Co bit is the command MSB and defines if after this command will follow one data byte and an other command word or if will follow a stream of data (Co = 1 Command word, Co = 0 Stream of data). The D/C bit defines whether the data byte is a command or RAM data (D/C = 1 RAM Data, D/C = 0 Command). If Co =1 and D/C = 0 the incoming data byte is decoded as a command, and if Co =1 and D/C =1, the following data byte will be stored in the data RAM at the location specified by the data pointer. Every byte of a command word must be acknowledged by all addressed units. After the last control byte, if D/C is set to a logic 1 the incoming data bytes are stored inside the STE2002 Display RAM starting at the address specified by the data pointer. The data pointer is automatically updated after every byte written and in the end points to the last RAM location written. Every byte must be acknowledged by all addressed units.
Reading mode
If the R/W bit is set to logic 1 the chip will output data immediately after the slave address. If the D/C bit sent during the last write access, is set to a logic 0, the byte read is the status byte.

Serial interface
The STE2002 serial Interface is a bidirectional link between the display driver and the application supervisor. It consists of five lines: two for data signals (SDIN, SOUT), one for clock signals (SCLK), one for the peripheral enable (SCE) and one for mode selection (SD/C). The serial interface is active only if the SCE line is set to a logic 0. When SCE line is high the serial peripheral power consumption is zero. While SCE pin is high the serial interface is kept in reset. The STE2002 is always a slave on the bus and receive the communication clock on the SCLK pin from the master. Information are exchanged byte-wide. During data transfer, the data line is sampled on the positive SCLK edge. SD/C line status indicates whether the byte is a command (SD/C =0) or RAM data (SD/C =1);it is read on the eighth SCLK clock pulse during every byte transfer. If SCE stays low after the last bit of a command/data byte, the serial interface expects the MSB of the next byte at the next SCLK positive edge. A reset pulse on RES pin interrupts the transmission. No data is written into the data RAM and all the internal registers are cleared. If SCE is low after the positive edge of RES, the serial interface is ready to receive data. Throughout SOUT can be read only the driver I2C slave address. The Command sequence that allows to read I2C slave address is reported in Fig. 34 & 35. SOUT is in High impedance in steady state and during data write. It is possible to short circuit DOUT and SDIN and read I2C address without any additional lines.

Parallel interface
The STE2002 parallel Interface is a bidirectional link between the display driver and the application supervisor. It consists of eleven lines: eight data lines (from DB7 to DB0) and three control lines. The control lines are: enable (E) for data latch, PD/C for mode selection and R/W for reading or writing. The data lines and the control line values are internally latched on E rising edge (fig. 50). When the parallel interface is selected, if R/W line is set to "one", D0-D7 lines are configured as output drivers (low impedence) and it is possible to read the driver I2C address (Fig. 51)
