Overview

M2 is designed to provide absolute top performance for a wide spectrum of teletext and graphic applications in standard and high end TV-sets and VCRs. M2 contains a data caption unit, a display unit and a high performance Infineon C16x based microcontroller (so that M2 becomes a one chip TV-controller) an up to level 3.5 teletext decoder and display processor with enhanced graphic accelerator capabilities. It is not only optimized for teletext usage but also, due to its extremely efficient architecture, can be used as a universal graphic engine.
