1 Introduction

This application note describes the hardware required to interface the S1D13705 Embedded Memory LCD Controller and the Motorola “Dragonball” family of micropro- cessors. Each “Dragonball” microprocessor, the MC68328, the MC68EZ328, and the MC68VZ328, will be described in their own sections.

By implementing an embedded display refresh buffer, the S1D13705 can reduce system power consumption, improve image quality, and increase system performance as compared to the Dragonball’s on-chip LCD controller.

The designs described in this document are presented only as examples of how such interfaces might be implemented. This application note will be updated as appropriate. Please check the Epson Electronics America website at http://www.eea.epson.com for the latest revision of this document before beginning any development.
