PCA85276

Automotive 40 x 4 LCD driver

13. Application information

13.1 Cascaded operation

Large display configurations of up to 8 PCA85276 can be recognized on the same I2C-bus

by using the 2-bit hardware subaddress (A0 and A1) and the programmable I2C-bus slave

address (SA0).

When cascaded PCA85276 are synchronized, they can share the backplane signals from

one of the devices in the cascade. The other PCA85276 of the cascade contribute

additional segment outputs. The backplanes can either be connected together to enhance

the drive capability or some can be left open-circuit (such as the ones from the slave

in Figure 26) or just some of the master and some of the slave will be taken to facilitate the

layout of the PCB.
