The PCF8831 is a row driver for driving colour STN displays manufactured by Philips Semiconductors.
The PCF8831 is a row driver IC for colour STN LCD displays, intended to be used together with the PCF8832 column driver. It provides 160 selectable row outputs and supports functions such as scan direction selection, display off, and N‑line inversion, making it suitable for mobile phones, PDAs, automotive information systems, point‑of‑sale terminals, and instrumentation.
Key features include a logic supply voltage of 2.4 V to 3.5 V, a display supply range of 15 V to 40 V, low power consumption for battery‑operated devices, and CMOS‑compatible inputs. The datasheet supplies pin assignments, block diagrams, functional descriptions, limiting values, and handling instructions for designers.
