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.
