PCA8576C
Automotive LCD driver for low multiplex rates
Fig 29. Cascaded PCA8576C configuration
The SYNC line is provided to maintain the correct synchronization between all cascaded
PCA8576Cs. This synchronization is guaranteed after the power-on reset. The only time
that SYNC is likely to be needed is if synchronization is accidentally lost (e.g. by noise in
adverse electrical environments; or by the defining a multiplex mode when PCA8576Cs
with differing SA0 levels are cascaded).
SYNC is organized as an input/output pin; the output selection being realized as an
open-drain driver with an internal pull-up resistor. A PCA8576C asserts the SYNC line and
monitors the SYNC line at all other times. If synchronization in the cascade is lost, it is
restored by the first PCA8576C to assert SYNC. The timing relationship between the
backplane waveforms and the SYNC signal for the various drive modes of the PCA8576C
are shown in Figure 30 .
