Fig 5. Typical system configuration

The host microcontroller maintains the 2-line I2C-bus communication channel with the

PCA85132.

Biasing voltages for the multiplexed LCD waveforms are generated internally, removing

the need for an external bias generator. The internal oscillator is selected by connecting

pin OSC to VSS. The only other connections required to complete the system are the

power supplies (VDD, VSS, and VLCD) and the LCD panel selected for the application.
