Description
Fig. 1
Pad Assignment
The V6123 is a low multiplex LCD driver. The 2, 4 and 8
way multiplex is digitally programmable by the command
byte. The display refresh is handled on chip by an internal
RC oscillator via 1 selectable 8 x 60 RAM which holds the
LCD content driven by the driver. LCD pixels (or segments) are addressed on a one to one basis with the 8 x
60 bit RAM (a set bit corresponds to an activated LCD
pixel).
The V6123 has a very low dynamic current consumption,
typically 175 µA at VDD = 5 V, VLCD = 7 V, making it particularly attractive for portable and battery powered products.
The wide operating range on supply voltages and tem perature offers much application flexibility. The LCD 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.

The V6123 has internal voltage bias level generation. When
driving large pixels, an external resistor divider chain can be
connnected to the voltage bias level inputs to obtain enhanced
display contrast. See Fig. 11, 12 and 13. The external resistor
divider ratio should be in accordance with the internal resistor
ratio (see Table 8).

Functional Description
Supply Voltage VLCD, VDD, VSS
The voltage between VDD and V SS is the supply voltage for
the logic and the interface. The voltage between VLCD and
VSS is the supply voltage for the LCD and is used for the
generation of the internal LCD bias level which have a
maximum impedance of 30 kΩ for a voltage from 3 to
8.5 V. Without external connections to the V1, V2, V3 bias
level inputs, the V6123 can drive most medium sized LCD
(pixel aera up to 4’000 mm2).
For displays with a wide variation in pixel sizes, the configuration shown in Fig. 12 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
V6123. An external bias generation circuit can lower the
bias level impedance and hence improve the LCD con trast (see Fig. 11). The optimum values of R, Rx and C,
vary according to the LCD size used and VLCD. 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. 13
should be used.
When V6123 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 en hanced display contrast as the effective bias level source
impedance is the parallel combination of the total number of drivers. For example, if two V6123 are cascaded as
shown in Fig. 10, then the maximum bias level impedance becomes 15 kΩ for a VLCD voltage from 3 to 8.5 V.
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 V6123 2 and 8 mux programmed, and for the
V6123 4 mux programmed, VLCD > V1 > V2, and V3 = V SS.
Data Input / Output
The data input pin, DI, is used to load serial data into the
V6123. The serial data word length is 68 bits. Data is
loaded in inverse numerical order, the data for bit 68 is
loaded first, the data for bit 1 last. The column data bits
are loaded first and then the command byte (see Fig. 5).
The data output pin, DO, is used in cascaded application
(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
68 clock periods. In order to cascade V6123s, 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 V6123 (the
one that does not have DO connected) must be loaded
first and the data for the first V6123 (it is DI connected to
the processor) loaded last.
10
The display RAM word length is 60 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 down loading data to the V6123,
any display RAM address can be chosen. Display RAM
address is given by command bits 3 to 5. Bit 6 forces all
column outputs at 0L (display OFF). Bit 7 forces all col umn outputs at 1L (display ON). If bit 7 (SET) and bit 6
(BLANK) are both active, the initialization function is activated. This function is used to synchronize the chip at row
one. The command bit 2 (COL) defines the V6123 as a
row and column driver or column driver only. The V6123
functions as row and column driver while the bit 2 (COL)
is inactive. When active, the bit 2 configures the V6123 to
function as column driver only. The former row outputs
function as column outputs. In cascaded applications,
one V6123 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
V6123s never cascade one mux mode number with an other. If a V6123 8 mux programmed is used to drive the
rows, then only V6123 8 mux programmed can be cas caded with it.
The command bits, bit 1 and bit 0, define the mux mode
(see Fig. 5).
CLK Input
The clock input is used to clock the DI serial data into the
shift register, to latch the data from the shift register into
the RAM .
After loading data into the shift register, the clock has to
stay 0 logic during TSTR.
After TSTR pulse, the data are latched into the RAM.
FR Input / Output
The frame frequency is realized by an internal RC oscillator with a typical value of 55 Hz. The internal row frequency changes with the number of rows (Frow = 55 x n,
where n = 2, 4 or 8).
When bit 2 (COL) is inactive (row and column driver), the
frame frequency is given by the internal oscillator. This
frequency can also be used at FR output to drive
casecaded V6123.
When bit 2 (COL) is active (column driver only), the frame
frequency is external then the frequency is given by the
row and column driver directly to the FR input. In cascaded applications, the row and column driver (FR, output) give the frame frequency to all the cascaded chip
(FR, input).
Driver Outputs S1 to S60
There are 60 LCD driver outputs on the V6123. When bit 2
(COL) is inactive, the outputs S1 to Sn function as row
drivers and the outputs S(n+1) to S60 function as column
drivers. Where n is the V6123 mux mode number (2, 4 or
8).
When bit 2 (COL) is active, all 60 outputs function as column drivers (see Table 6). There is a one to one relationship between the display RAM and the LCD driver
V6123
outputs. Each pixel (segment) driven by the V6123 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”.
Power-Up
On power up the data in the shift registers, the display
RAM, the sequencer driving the 2/4/8 rows and the 60 bit
display latches are undefined.
Applications
Two V6123 8 Mux Programmed Cascaded
By connecting the V1, V2 and
V3 bias inputs 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 V6123 are
cascaded as above, then the
maximum bias level impedance becomes 15 kΩ.
