Selecting a microscontroller

Saravana Muthu over 17 years ago

Hi to all,

Greetings.
I am going to use 3 Serial I/O RS 232 DB9 interface for data transmission.
Can any one tell me which microcontroller that supports it?

I'm not aware of any microcontroller that allows connecting RS-232-levels directly to its pins.

However, if you are looking for a microcontroller with 3 UARTs, then the device database, which can be found here on this site and can be conveniently searched, is at your disposal.

Neither am I!

Also, it is entirely irrelevant to the microcontroller what kind of connector you use!

I always thought processors could be bought in DIL28, DIL40, PLCC44, DSUB9, DSUB25, ... sockets.
