PCF85162
Universal LCD driver for low multiplex rates
12. Application information
12.1 Cascaded operation
Large display configurations of up to 16 PCF85162 can be recognized on the same
I2C-bus by using the 3-bit hardware subaddress (A0, A1, and A2) and the programmable
I2C-bus slave address (SA0).
When cascaded PCF85162 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 PCF85162 of the cascade contribute
additional segment outputs, but their backplane outputs are left open-circuit
Table 18.
