r16c renesas

Hello all
i'am using a Renesas R16C/Tiny for a project.

Now i power the Mcu with 5V. and the output are 5v.
If i power it with 3.3 V , can i still controle TTL device ??


Also can someone post some code samples for I2C Communication and RS232 ??


Thank you in advance

no the outputs will be 3.3v
you have two solutions
1) use level converters
2)use TTl with vOH near 3.3 v
