CP2401-GM 128 Segment LCD Controller
The CP2401-GM low power LCD controller can drive up to 128 LCD segments. These devices are easily interfaced with any microcontroller using an I2C interface. A benefit to this approach is designers can select the best-fit MCU for the system and then add the CP2401-GM to handle LCD requirements efficiently with respect to system size and power consumption. The device includes 36 digital I/O pins and is available in a QFN48 package (7x7).
