PCF8576
12.1
Chip-on-glass cascadability in single plane
In chip-on-glass technology, where driver devices are
bonded directly onto glass of the LCD, it is important that
the devices may be cascaded without the crossing of
conductors, but the paths of conductors can be continued
on the glass under the chip. All of this is facilitated by the
PCF8576 bonding pad layout (see Fig.30). Pads needing
bus interconnection between all PCF8576s of the cascade
are V
DD
, V
SS
, V
LCD
, CLK, SCL, SDA and SYNC. These
lines may be led to the corresponding pads of the next
PCF8576 through the wide opening between V
LCD
pad
and the backplane output pads. The only bus line that does
not require a second opening to lead through to the next
PCF8576 is V
LCD
, being the cascade centre. The placing
of V
LCD
adjacent to V
SS
allows the two supplies to be
connected together.
When an external clocking source is to be used, OSC of all
devices should be connected to V
DD
.
The pads OSC, A0, A1, A2 and SA0 have been placed
between V
SS
and V
DD
to facilitate wiring of oscillator,
hardware subaddress and slave address.
