R V6116 Copyright © 2005, EM Microelectronic-Marin SA 10 www.emmicroelectronic.com Functional Description Supply Voltage VLCD, VDD, VSS The voltage between VDD and VSS is the supply voltage for the logic and the interface. The voltage between V LCD and VSS is the supply voltage for the LCD and is used for the generation of the internal LCD bias levels. The internal LCD bias levels have a maximum impedance of 25 k Ω for a VLCD voltage from 3 to 8V. Without external connections to the V1, V2, V3 bias level inputs, the V6116 can drive most medium sized LCD (pixel area up to 4'000 mm2). For displays with a wide va riation in pixel sizes, the configuration shown in Fig. 13 can give enhanced contrast by giving faster pixel switching times. On changing the row polarity (see Fig. 7, 8 and 9) the parallel capacitors lower the impedance of the bias level generation to the peak current, giving faster pixel charge times and thus a higher RMS "on" value. A higher RMS "on" value can give better contrast. IF for a given LCD size and operating voltage, the "off" pixels appear "on", or there is poor contrast, then an external bias level generation circuit can be used with the V6116. An external bias generation circuit can lower the bias level impedance and hence improve the LCD contrast (see Fig. 12). The optimum values of R, Rx and C, vary according to the LCD size used and V LCD. They are best determined through actual experimentation with the LCD. For LCD with very large average pixel area (eg. up to 10'000 mm2), the bias level configuration shown in Fig. 14 should be used. When V6116s are cascaded, connect the V1, V2 and V3 bias inputs as shown in Fig. 10. The pixel load is averaged across all the cascaded drivers. This will give enhanced display contrast as the effective bias level source impedance is the parallel combination of the total number of drivers. For example, if two V6116 are cascaded as shown in Fig. 10, then the maximum bias level impedance becomes 12.5 kΩ for a V LCD voltage from 3 to 8V. Table 8 shows the relationship between V1, V2 and V3 for the multiplex rates 2, 4 and 8. Note that V LCD > V1 > V2 > V3 for the V6116 2 and V6116 8, and for the V6116 4, VLCD > V1 > V2 and V3 = VSS. Data Input /Output The data input pin, DI, is used to load serial data into the V6116. The serial data word length is 48 bits. Data are loaded in inverse numerical order, the data for bit 48 is loaded first and the data for bit 1 last. The column data bits are loaded first and then the command bits (see Fig. 5). The data output pin, DO, is used in cascaded applications (see Fig. 10). DO transfers the data to the next cascaded chip. The data at DO is equal to the data at DI delayed by 48 clock periods. In order to cascade V6116s, the DO of one chip must be connected to DI of the following chip (see Fig. 10). In cascaded applications the data for the last V6116 (the one that does not have DO connected) must be loaded first and the data for the first V6116 (its DI is connected to the processor) loaded last (see Fig. 10). The display selected RAM word length is 40 bits (see Fig. 6). Each LCD row has a corresponding display RAM address which provides the column data (on or off) when the row is selected (on). When downloading data to the V6116, any display selected RAM address can be chosen. Display selected RAM address is given by command bits 3 to 5, the RAM is selected with the command bit 2. If bit 2 = 0, then RAM 1 can be written and RAM 2 is read. When falling edge of STR and RAM- Add = 0, then RAM 1 will be read. If bit 2 = 1, then RAM 2 can be written and RAM 1 is read. When falling edge of STR and RAM-Add = 0, then RAM 2 will be read. This last sequence synchronizes the V6116s when cascaded. Bit 7 forces all column outputs at 0L (display OFF). Bit 6 forces all column outputs at 1L (display ON). When bit 6 (SET) and bit 7 (BLANK) are active, the BLANK function has priority. The command bits, bit 6 and bit 7, are activated when logic 1. The command bits, bit 1 and bit 0, define the mux mode (see Fig. 4). CLK Input The CLK input is used to clock the DI serial data into the shift register and to clock the DO serial data out. Loading and shifting of the data occurs at the falling edge of this clock, outputting of the data at the rising edge (see Fig. 3). When cascading devices, all CLK lines should be tied together (see Fig. 10). STR Input The STR input is used to write to the display RAM, to blank the LCD (V6116 060), and to synchronize cascaded V6116s. The STR input writes the data loaded into the shift register, on the DI input, to the display selected RAM on the falling edge of the STR signal. The STR input when high blanks the LCD by disconnecting the internal voltage bias generation from the V SS potential (V6116 060). Segment outputs S1 to S40 (rows and columns) are pulled up to V LCD. The delay to driving the LCD with V LCD on S1 to S40, is dependent on the capacitive load of the LCD and is typically 1 µs. An LCD pixel responds to RMS voltage and takes approximately 100 ms to turn on or off. The delay from putting STR high to the LCD being blank is dependent on the LCD off time and is typically 100 ms. In applications which have a long STR pulse width (10 µs) the LCD is driven by V LCD on both the rows and columns during this time. As the time is short (1 µs), it will have zero measurable effect on the RMS "on" value (over 100 ms) of an LCD pixel and also zero measurable effect on the pixel DC component. Such STR pulses will not be visible to the human eye on an LCD. Note: if an external voltage bias generation circuit is used as shown in Fig. 12 to 14, the LCD blank function (STR high) will not blank the LCD. Fig. 15 (only available for the V6116 060, with internal resistor) shows how to do a BLANK with the external resistor divider bias by STR signal. When STR is high, the LCD will be driven by the parallel combination of the external voltage bias generation circuit and part of the internal voltage bias generation circuit. The STR input is used also to synchronize the V6116's circuit when cascaded. The synchronization occurs on the falling edge of the STR signal, provided bit 6 and 7 preset to 11. The synchronization will set effective on the next falling edge of the FR signal. A time frame begins with row 1 and so the LCD picture is rebuilt from row 1 each time cascaded V6116s are synchronized. When cascading devices, all STR lines must be tied together (see Fig. 10). FR Input The FR signal controls the segment output frequency generation (see Fig. 7, 8 and 9). To avoid having DC on the display, the FR signal must have a 50% duty cycle. The frequency of the FR signal must be n times the desired display refresh rate, where n is the V6116 mux mode no. (2, 4 or 8). For example, if the desired refresh rate is 40 Hz, the FR signal frequency must be 320 Hz for

R V6116 Copyright © 2005, EM Microelectronic-Marin SA 11 www.emmicroelectronic.com the V6116 8. A selected row (on) is in phase with the FR signal (see Fig. 7, 8 and 9). It is recommended that data transfer to the V6116 should be synchronized to the FR signal to avoid a falling or rising edge on the FR signal while writing data to the V6116. The LCD pixels change polarity with the FR signal. On the edges of the FR signal current spikes will appear on the V SS and V LCD supply lines. If the supply lines have high impedance then voltage spikes will appear. These voltage spikes could interfere with data loading on the DI and CLK pins. The V6116 has filters in order to reduce perturbation on the input signals. It is also recommended that data transfer to the V6116 should be synchronized to the FR signal to avoid DC component which may especially appear during Blink function. Driver Outputs S1 to S40 There are 40 LCD driver outputs on the V6116. When COL is inactive, the outputs S1 to Sn function as row drivers and the outputs S(n+1) to S40 function as column drivers, where n is the V6116 mux mode no. (2, 4 or 8). When COL is active, all 40 outputs function as column drivers (see Table 6). There is a one to one relationship between the display selected RAM and the LCD driver outputs. Each pixel (segment) driven by the V6116 on the LCD has a display RAM bit which corresponds to it. Setting the bit turns the segment "on" and clearing it turns it "off". COL Input The V6116 functions as a row and column driver while the COL input is inactive. When active, the COL input configures the V6116 to function as a column driver only. The former row outputs function as column outputs. In cascaded applications, one V6116 should be used in the row and column configuration ( COL inactive) and the rest as pure column drivers ( COL active) (see Fig. 10). Note: when cascading V6116s never cascade one mux mode no. with another. If a V6116 mux mode 8 is used to drive the rows, then only V6116s mux mode 8 can be cascaded with it (see Fig. 10). Power Up On power up the data in the shift registers, the two display RAMs and the 40 bit display latches are undefined. The STR input and the command bit 7 should be taken high on power up to blank the display, then the display data written to the display selected RAM (see Fig. 11). When finished the initial write to the display selected RAM, take the STR input low to display the display selected RAM contents (see also section "STR Input").

Applications

Two V6116 Mux Mode 8 Cascaded By connecting the V1, V2 and V3 bias outputs as shown, the pixel load is averaged across all the drivers. The effective bias level source impedance is the parallel combination of the total number of drivers. For example, if two V6116 are cascaded as above, then the maximum bias level impedance becomes 12.5 kΩ. Fig. 10
