Pin Functions
Power Supply Pins
V
CC1
to V
CC3
, GND1 to GND5:
These pins supply power to the logic circuit.
VCH1 and VCH2:
These pins supply power to the liquid crystal circuits and level supplies for LCD
driver. The same voltage must be supplied.
VM1, VM2, VCL1, VCL2:
These Pins input the level supply for LCD driver. The same voltage must be
supplied to VM1 and VM2, VCL1 and VCL2.
Control Signals
LS0, LS1 and LS2 (Input):
The LS pins can assign eight (0 to 7) ID numbers to eight LSIs, thus making it
possible to connect a maximum of eight HD66522s sharing the same CS pin to the same bus (Figure 2).
SHL (Input):
This pin reserves the relationship between LCD drive output pins Y1 to Y160 and addresses.
There is no need to change the addresses assignment for the display regardless of whether the HD66522 is
mounted from the back or the front of the LCD panel. Refer to Driver Layout and Address Management for
details.
FLM (Input):
When the pin is high, it resets the display line counter, returns the display line to the start
line, and synchronizes common signals with frame timing.
CL1 (Input):
At each falling edge of data-transfer clock pulses input to this pin, the latch circuits latch
display data and output it to the liquid crystal display driver section.
FX0 and FX1 (Input):
Scanning function data signal to select LCD driver output. Connect with FX0, FX1
pins of common driver HD66523R.
DISPOFF
(Input):
A control signal to fix liquid crystal driver output to liquid crystal deselect level. When
this pin is low, liquid crystal drive outputs Y1 to Y160 are set to liquid crystal deselect level VM. The
display can be turned off by setting the outputs of the common driver to level VM. In this case, display
RAM data will be retained. Therefore, if signal
DISPOFF
returns to high level, liquid crystal drive outputs
will return to normal display state. Draw access can be executed when signal
DISPOFF
is either in high or
low state.
RESET
(Input):
Low level of
RESET
stops internal operation and initializes internal registers and
counters.
