Notes

• Bare Die Package: Pin numbers/pad coordinates are not provided in the source material. The datasheet lists functional pin names but does not include a detailed pad map with numerical or coordinate designations.
• Interface Mode Selection: The IM2, IM1, IM0 pins determine the communication protocol (MIPI-DBI Type B parallel, MIPI-DBI Type C SPI, or MIPI DSI).
• Data Bus Width: DB[23:0] usage varies by interface mode (8-bit to 24-bit).
• Unused Pins: Most control and output pins should be fixed to IOVCC, DGND, or left open as specified to prevent noise and undefined behavior.
• Power Supply Decoupling: All power pins (VCI, IOVCC, VDD) require stabilizing capacitors to GND for stable operation.

The absolute maximum ratings are listed in Table 41. When the ILI9488 is used beyond the absolute maximum ratings, it may be permanently damaged. Using the ILI9488 within the following limits of electrical characteristics is strongly recommended for normal operation. If these electrical characteristic conditions are exceeded during normal operation, the ILI9488 will malfunction and cause poor reliability.
