General Description
The LSC016I02-QS-V1 is a high-performance square display module featuring exceptional pixel density for its size. Its 1.6-inch IPS panel with 400x400 resolution provides extremely sharp and detailed imagery, ideal for displaying fine graphics, text, or medical images. The module supports a high-speed QSPI interface (using multiple data lines for faster transfer) alongside a standard SPI interface, offering flexibility for different host MCU capabilities.
A key feature is the dedicated touch panel interface via I²C, with pins for clock, data, reset, and interrupt, enabling easy integration of a capacitive touch panel. The specification includes detailed pin descriptions covering display, touch, and power pins. It also provides comprehensive SPI/QSPI timing characteristics for both write and read operations, including access times and output disable times.
