[SOLVED] MIcrocontroller having 5 UART

[parthasarthimalani]

Hi,

I want to use a microcontroller having 5 UART and 50 GPIO.
Can anybody suggest me which controller should I use?

 

[andre_luis]

I particularly don't know any option available of any manufacturer with such an amount of identical resources. Have you considered using a soft core?

 

[hexreader]

Use PIC32MX795F512L

stm32f103vet6

Does it have to be in DIP package?

 

[shaiko]

Many options exist.
Do you have a manufacturer preference?

I think, DIP packages was actual 20 year ago. Now you have to buy devboard if you wish to play with that first.

Thanks for kind reply

Package is not important.
Peripherals is a important prospectus for me.

No manufacturer preference.
But controller should be cheap in cost

You can go for PSoC (FreeSoC development environment). You can add 5 or more UARTs to it and write the code in C language.

I bet a Microchip PIC will be more cost effective - But you can also check this list from ST:

Interestng to hear that, due that in the occasion when I used this core (the top of PSoC®3), the amount of digital blocs available were not enough to build more than 4 UARTs ( 3 full-duplex + 1 half-duplex, if I remember correctly ), but actually this were long time ago.

I have used FreeSoC and it has sufficient pins for 5 UARTs. Just now I checked and found that there is FreeSoC2 which has Arduino2560 form. It has still more pins.

The Kinetis K-series from NXP has up to 6 uarts and a load of other functions. it's an ARM Cortex M4 kernel with several levels of inbuilt devices. Note the overlapping IO-setup for different functions.

[shaiko]

No such thing as a ARM Cortex M4 kernel - perhaps you meant core?

 

[Gorgon]

Sorry, yes I meant core. The main thing however was the 6 UARTs, if you can see past the brainfart.
