Figure 23: Reference Circuit Design for LCM1 Interface
MIPI are high speed signal lines. It is recommended that common-mode filters should be added in series
near the LCM connector, so as to improve protection against electromagnetic radiation interference.
ICMEF112P900MFR using ICT is recommended.
When compatible design with other displays is required, please connect the LCD_ID pin of LCM to the
module’s ADC pin, and please note that the output voltage of LCD_ID cannot exceed the voltage range of
ADC pin.
3.19. Touch Panel Interfaces
SC66 provides two I2C interfaces for connection with Touch Panel (TP), and also provides the
