Hi,

We are designing a battery powered device.

UART signals from MCU are on 3V level and RS232 signals are on 5V. Can anyone please suggest any Transceiver IC with inbuilt level translator in it with cost optimised solution?

RS-232 does not use 5 V but allows anything between ± 3 V and ± 25 V. Therefore, RS-232 requires special transceivers.

Priyanka,

How many input and output channels does the UART have?

Here are devices with logic voltage translation or low VCC operation.
