TPU 3040

The TPU 3040 is an integrated circuit designed in CMOS technology. As a stand-alone system or in combination with the DIGIT 3000 system, the TPU 3040 offers a wide range of new and interesting features, some of them unique in comparison with other products on the market.

The TPU 3035 is a stripped-down version of TPU 3040, designed for low-cost applications. The basic chip architecture remains unchanged, whereas some of the more sophisticated features are removed (see Tab 11). In the following description only the TPU 3040 is mentioned.

The TPU 3040 is a single chip World System Teletext (WST) decoder for applications in analog and digital TV sets. Based on a 65C02 core with RAM and ROM on chip, an adaptive data slicer, a display controller and a number of interfaces, the TPU 3040 offers acquisition and display of various teletext and data services such as WST, PDC, VPS and WSS.
