Automotive LCD driver for low multiplex rates
13. Application information
13.1 Cascaded operation
In large display configurations, up to 16 PCA8576Cs can be recognized on the same
I 2 C-bus by using the 3-bit hardware subaddress (A0, A1 and A2) and the programmable
I 2 C-bus slave address (SA0).

Cascaded PCA8576Cs are synchronized. They can share the backplane signals from one
of the devices in the cascade. Such an arrangement is cost-effective in large LCD
applications since the backplane outputs of only one device need to be through-plated to
the backplane electrodes of the display. The other PCA8576C of the cascade contribute
additional segment outputs. The backplanes can either be connected together to enhance
the drive capability, some can be left open-circuit (as shown in Figure 29 ) or just some of
one and some of the other device can be taken to facilitate the layout of the display.
