STV8105 is a low-power, controller/driver “combo” IC for OLED displays. It supports 256 columns by 72 rows with 16 levels of gray for monochrome and 2 x 128 columns by 72 rows with 16 levels of gray for “two” color displays.
The STV8105 is a low‑power, monochrome OLED passive‑matrix controller/driver from STMicroelectronics. It supports a variety of display formats, including 256 × 72 with 4‑bit (16 gray levels) and other resolutions, and offers selectable 8‑bit parallel and serial interfaces for easy integration with host micro‑controllers. The on‑chip DC/DC step‑up converter supplies the necessary display voltage, while integrated bias and driver circuits reduce external component count.
The document details the functional description, pin assignments, electrical characteristics, and programming of the device. It includes memory maps for different gray‑scale modes, brightness adjustment registers, and information on the dual‑port display RAM. Electrical limits, thermal data, and recommended operating conditions are also provided, along with revision history and safety notices.
