CP2403-GM 64 Segment LCD Controller
The CP2403-GM low power LCD controller can drive up to 64 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 CP2403-GM to handle LCD requirements efficiently with respect to system size and power consumption. The device includes 20 digital I/O pins and is available in a QFN32 package (5x5).
