Product data sheet Rev. 2 — 25 September 2014 33 of 103 NXP Semiconductors PCA8530 Automotive 102 x 4 Chip-On-Glass LCD segment driver The host microcontroller maintains the communication channel with the PCA8530. The only other connections required to complete the system are the power supplies, the VLCD pins, the external capacitors, and the LCD panel selected for the application. The appropriate biasing voltages for the multiplexed LCD waveforms are generated internally. VDD1 to VDD3 from 2.5 V to 5.5 V. VDD1 to VDD3 can be connected to the same power supply. VSS1 to VSS3 can be connected to the same ground supply. Fig 12. Typical system configuration if using the internal VLCD generation and I2C-bus VDD1 to VDD3 from 2.5 V to 5.5 V. VDD1 to VDD3 can be connected to the same power supply. VSS1 to VSS3 can be connected to the same ground supply. Fig 13. Typical system configuration if using the external VLCD and SPI-bus |
