It operates from a dual supply of 1.8V and 3.3V, keeping the digital core and analog front-end on separate rails for noise isolation. The serial control interface lets firmware adjust scaling, contrast, and sync timing without extra GPIOs. ## 80-LQFP footprint and rework notes The fine-pitch leads need a clean solder paste stencil and a reflow profile matched to the board's thermal mass.","metaTitle":"TW8831-LB1-CR Techwell Video LCD Controller, 80-LQFP","metaDescription":"TW8831-LB1-CR Techwell video LCD controller supports NTSC, PAL, SECAM. 80-LQFP package, 1.8V/3.3V supply.
