Seiko Epson and E Ink announced a new joinly developed display controller IC, the  S1D13522, which provides a high performance, space saving solution for E Ink's Vizplex-enabled electronic paper displays. The new IC is based on the same powerful engine as the first model, the S1D13521, but provides customers with a higher level of performance and additional features.

The new Epson display controller (code named ISIS) includes 2M bytes of embedded memory and features that greatly reduce the CPU overhead for EPD applications. Allowing multi-regional and concurrent display updates, the S1D13522 adds interface support for direct Touch/Pen drawing. In addition Picture-in-Picture, Rotation, Transparency, and Hardware Cursor functions further increase flexibility in delivering the optimal display experience.

The Advanced Sequencer Engine, Power Management, I2C Thermal Sensor, and optional Serial Flash Memory support make a variety of implementations possible. The new controller also adds interfaces for PMIC I/F and panel auto ID read. Combining all these unique features enables application developers to develop products more efficiently. The S1D13522 is the ideal choice for new EPD designs and design upgrades. Samples of the Epson S1D13522 are available now. Sample price is $20. Production quantities will be available in January 2010.

E Ink plans to offer an ISIS prototype kit that will enable engineers to rapidly prototype and develop next generation ePaper products. Details will be announced when kits are available.
