microcontroller with many serial port

[ahmadagha23]

Hi
I am looking for a microcontroller with the following features:

rs422 6 ports
rs232 2 ports
spi 4 ports
data port 32 bits
address port 12 bits
Do you know any microcontroller with these fatures?

Regards

I have corrected the quote above for what I think you meant to say.

I do not think you will find any microcontroller that outputs RS232, only Asynchronous serial at TTL levels.
Microcontrollers with RS422 may exist, but if they do, I bet they are rare.

The only way I see to reach that is building someone in FPGA technology like for example in NEOS2 from ALTERA

you have a demanding requirement! never seen anything like it!
some of the Microchip PIC32 microcontrollers have 6 UARTs, 4 SPI, parallel port 16-bit data and 16 address lines
32-bit PIC Microcontrollers - 32-bit PIC Microcontrollers

have look at Freescale - I seem to remember some of their microcontrollers have 8 or 10 UARTs
also ARM and Texas microcontrollers

can u describe the application for what u need so much demanding uC

 

[Embedded_Geek]

ARM based controller like lpc2148

Specify your requirements and get the microcontroller of your choice!

describe your application first. I never come across any microcontroller with these features.

The big jump of NIOS2 ALTERA architeture is that you can create any multiprocessor with any features ( according your specifications above ) inside 1 chip sharing ressources :

you could add extra rs422 ports by using a Maxim MAX3140 SPI UART with RS-485/RS-422 transceiver

hi,

Atmel ATXMEGA series controllers have lot of ports (SPI & UARTS) and wide range of configurations. so see if it will be helpful

Atmel Products - Atmel AVR 8- and 32-bit - AVR XMEGA

help, atxmega minimum system schematic?

what type of application that ur going to develop by using these many ports. good engineering should build with less resources.
any way u can find them in advanced AVR microcontroller versions
