HD66113T
(120-Channel Common Driver Packaged
in a Slim Tape Carrier Package)
Description
The HD66113T is a common driver for large dot matrix liquid crystal graphics displays. It features 120
channels which can be divided into two groups of 60 channels by selecting data input/output pins. The
driver is powered by about 3V, making it suitable for the design of portable equipment which fully utilizes
the low power dissipation of liquid crystal elements. The HD66113T, packaged in a slim tape carrier
package (slim-TCP), makes it possible to reduce the size of the user area (wiring area).

Pin Functions
Power Supply
V
CC
, GND:
Supply power to the internal logic circuits.
VLCD, GND:
Supply power to the LCD drive circuits (Figure 1).
V1L, V1R, V2L, V2R, V5L, V5R, V6L, V6R:
Supply different power levels to drive the LCD. V1 and
V2 are selected levels, and V5 and V6 are non-selected levels.
Control Signals
CL:
Inputs data shift clock pulses for the shift register. At the falling edge of each CL pulse, the shift
register shifts data input via the DIO pins.
M:
Changes the LCD drive outputs to AC.
CH:
Selects the data shift mode. (CH = high: 2
×
60-output mode, CH = low: 120-output mode)
SHL:
Selects the data shift direction for the shift register and the common signal scan direction (Figure 2).
DIO1, DIO2:
Input or output data. DIO1 is input and DIO2 is output when SHL is high. DIO1 is output
and DIO2 is input when SHL is low.
DI:
Input data. DI is input to X61–X120 when CH and SHL are high, and to X60–X1 when SHL is low.
DISPOFF:
Controls LCD output level. A low
DISPOFF
sets the LCD drive outputs X1–X120 to the V2
level. A high
DISPOFF
is normally used.
LCD Drive Outputs
X1–X120:
Each X outputs one of four voltage levels V1, V2, V5, or V6, depending on the combination of
the M signal and the data level (Figure 3).
