To see the supported TEDS chips, download the latest TEDS editor and check the TEDS device list. 

Here is the list of currently supported chips:

To define a minimum size for TEDS is almost impossible due to a lot of possible combinations depending on a wanted application.
But the recommended TEDS chip is DS2433 or DS24B33 with 4 kilobits of memory.

To write all kind of information to TEDS, like Linearization table, FrequencyResponse table and a full channel definition, the largest one DS28EC20 (20kBit) might be needed. So far, we didn't have a case where this chip was needed.
