LCD Segment Driver
CMOS
The MC141511A is an LCD frontplane (segment) driver chip which in­cludes a 656 x 8 display RAM. The MC68HC05L10 microcomputer is the companion device which provides the backplane drive.
The MC68HC05L10, together with one MC141511A, may be used to drive a 5248-pixel muxed-by-41 display or a 4096-pixel muxed-by-32 dis­play. Larger displays may be driven by adding additional MC141511A.
The MC141511A is a low operating voltage version of MC141511. It is pin to pin compatible to the MC141511.
See Application Note AN-HK-13A.

ELECTRICAL CHARACTERISTICS (Voltage Referenced to VSS, TA= 25˚C)
This device contains circuitry to protect the inputs against damage due to high static voltages or elec­tric fields; however, it is advised that normal precau­tions to be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit. For proper operation it is recom­mended that Vin and V
out
be constrained to the
range VSS < or = (Vin or V
out
) < or = VDD. Reliability of operation is enhanced if unused input are con­nected to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open. This device may be light sensitive. Caution should be taken to avoid exposure of this device to any light source during normal operation. This device is not radiation protected.

VDD AND V
SS
The main dc power is supplied to the part by these two connec­tions. VDD is the most-positive supply level for logic circuitry and VSS is ground.
V
LCD
This supply connection provides the voltage level for the segment drivers and is connected to the Vout connection of the MC68HC05L10 MCU.
V
SEGL
, V
SEGH
These inputs are connected to V2 and V3 of an external voltage divider. See Figure 4.
D0 - D7
These connections form an eight bit wide bidirectional data bus which are connected to D0 through D7 of the MC68HC05L10.
A0 - A9
These inputs form a ten-bit wide address bus for addressing the display RAM and are connected to A0 through A9 of the MC68HC05L10.
BPSYNC
This input is a periodic active-low signal from the MC68HC05L10 for timing synchronization. BPSYNC is connected to FRM of MC68HC05L10. See Figure 5.
BPCLK
This input may be run as high as 4.096 kHz (50% duty cycle). It provides the required frame frequency for the segment driver. It is con­nected to BPCLK of the MC68HC05L10. Thus, the frequency is usually
2.048 kHz. See Figure 5.
PHI2
This input is a bus clock input that is used for data bus timing syn­chronization. It is connected to P02 of MC68HC05L10.
SEG0 - SEG127
These 128 output lines provide the frontplane drive signals to the LCD panel. These outputs are forced to a low level while display is turned off. Any unused segment outputs should be left open.
CE
This is an active low chip enable input and is connected to either CS1, CS2, CS3 or CS4 of the MC68HC05L10.
LRS
The left-right selection input defines the direction of the segment driver display. See Figure 8. 0 or Low = SEG 0 - 127 1 or High = SEG 127 - 0
MS
This input selects how display RAM is addressed. Either a 1:32 or 1:41 multiplex ratio is possible. 0 or Low = 1:32 multiplex addressing 1 or High = 1:41 multiplex addressing
R/W
This input indicates which direction the data is to be passed over the data bus. When R/W is low , the LCD driv er reads data from the data bus (D0-D7). When R/W is high, the LCD driver writes data to the data bus (D0-D7). This input is connected to R/W of MC68HC05L10.
TEST
Allowing this connection to float or connecting it to VSS (GND) places the part in the normal mode of operation. This input has an on­chip pulldown resistance of approximately 1M.

OPERATION OF LCD DRIVER
INTRODUCTION
The MC141511 is LCD driver with selectable 1: 32 or 1: 41 multi­plex ratios. The device consists of the following functional blocks as shown in the Block Diagram.
CONTROL LOGIC - accepts the control signals from the MCU and generates internal signals for synchronisation.
DISPLAY RAM - stores the display data. Each bit of the display RAM has one-to-one correspondence to a pixel of the LCD. The display RAM is in vertical byte oriented format as shown in Figure 6 and the way the display RAM is addressed depends on the multiplexing mode of the LCD (Figure 8). With reference to Figure 6, the display RAM also contains 16 bytes of memory which is in horizontal format ($280-$28F). The display RAM is addressed when backplane reaches 41.
LEVEL SELECTOR - consists of a switching circuit to select appropriate voltage levels from an e xternal voltage divider. See figure 4.
SEGMENT DRIVERS - provides the segment driving signals to the LCD frontplane. See Figure 7.
The LCD driver clock is derived from the 2.048KHz BPCLK and frame frequency is 64 Hz for 1:32 multiplex and 50 Hz for 1:41 multiplex ratio. See Figure 5.
GENERATION OF LCD BIAS LEVELS
Refer to Figure 4. In order to obtain optimum contrast for LCD panels, the bias levels should be selected such that
BIAS = R/(4R+R1) = 1/(
MUX + 1) V1/VLCD = 1/( MUX + 1) V2/VLCD = 2/( MUX + 1) V3/VLCD = ( MUX - 1)/( MUX + 1) V4/VLCD =  MUX /( MUX + 1)
Example: Mux = 41 ----- Bias = 1: 7.4, R = 10K, R1 = 33K, VR = 100K Mux = 32 ----- Bias = 1: 6.6, R = 10K, R1 = 27K, VR = 100K
