HD61200
(LCD Driver with 80-Channel Outputs)
Description
The HD61200 is a column driver LSI for a large-
area dot matrix LCD. It employs 1/32 or more duty
cycle multiplexing method. It receives serial
display data from a micro controller or a display
control LSI, HD61830, etc., and generates liquid
crystal driving signals.
Features
• Liquid crystal display driver with serial/parallel
conversion function
• Internal liquid crystal display driver: 80 drivers
• Drives liquid crystal panels with 1/32–1/128
duty cycle multiplexing
• Can interface to LCD controllers, HD61830 and
HD61830B
• Data transfer rate: 2.5 MHz max
• Power supply: VCC: 5 V ± 10% (internal logic)
• Power supply voltage for liquid crystal display
drive: 8 V to 17 V
• CMOS process
Ordering Information

Power supply for liquid crystal drive.
V1L (V1R), V2L (V2R): Selection level
V3L (V3R), V4L (V4R): Non-selection level
Power supplies connected with V1L and V1R (V2L & V2R,
V3L & V3R, V4L & V4R) should have the same voltages.
Liquid crystal driver outputs.
Selects one of the 4 levels, V1, V2, V3, and V4.
Relation among output level, M, and display data (D) is

1 Controller Switch signal to convert liquid crystal drive waveform into
AC.
I Controller Synchronous signal (a counter is reset at high level).
Latch clock of display data (falling edge triggered).
Synchronized with the fall of CL1, liquid crystal driver
signals corresponding to the display data are output.
I Controller Shift clock of display data (D).
Falling edge triggered.
I Controller Input of serial display data (D).

Notes: 1. Applies to CL1, CL2, SHL, E, M, DL, and DR.
2. Applies to CAR.
3. Applies to V1L, V1R, V2L, V2R, V3L, V3R, V4L, and V4R.
4. Specified when display data is transferred under following conditions:
CL2 frequency fCP2 = 2.5 MHz (data transfer rate)
CL1 frequency fCP1 = 4.48 kHz (data latch frequency)
M frequency fM = 35 Hz (frame frequency/2)
Specified at VIH = VCC (V), VIL = 0 V and load on outputs.
IGND: currents between VCC and GND.
IEE: currents between VCC and VEE.
5. Resistance between terminal Y and terminal V (one of V1L, V1R, V2L, V2R, V3L, V3R, V4L, and
V4R when load current flows through one of the terminals Y1 to Y80. This value is specified
under the following condition:
VCC – VEE = 17 V
V1L = V1R, V3L = V3R = VCC – 2/7 (VCC – VEE)
V2L = V2R, V4L = V4R = VEE + 2/7 (VCC – VEE)
