UART application circuits

Providing the full RS-232 functionality (using the complete V.24 link)

If RS-232 compatible signal levels are needed to provide full RS-232 (9 lines) functionality, two
different external voltage translators (e.g. Maxim MAX3237E and Texas Instruments
SN74AVC4T774) can be used. The Texas Instruments chip provides the translation from 1.8 V to 3.3
V, while the Maxim chip provides the translation from 3.3 V to an RS-232 compatible signal level.

If a 1.8V application processor is used for complete RS-232 functionality conforming to the ITU
Recommendation

] in DTE/DCE serial communication, the complete UART interface of the module

(DCE) must be connected to a 1.8 V DTE as described in
